Two-Tier Encryption in the UK

Alexander Cohen:

The Post reported that UK security officials had issued such a TCN, in secret, in January 2025, requesting that Apple create a way to access encrypted iCloud data belonging not just to UK users, but to Apple users worldwide. The chutzpah of it all was astonishing.

Apple’s position (privately, since they were prohibited from commenting publicly on the reported TCN) showed fidelity to its previous stance: deliberately weakening end-to-end encryption, for whatever purpose or for whomever the intended beneficiary, would make every user less secure. So the dispute became the UK government saying it needed access, Apple saying it couldn’t decrypt the data, and the UK effectively replying: then change the system so that you can.

[…]

Faced with a legal order that would have required it to change the security architecture on which ADP depended, Apple found a third option: stop offering the feature that made this dilemma exist in the first place. It reverted affected UK iCloud data to Standard Data Protection, where Apple does hold the keys and can respond to lawful legal process (except the baseline categories that stay end-to-end encrypted either way). This satisfied the underlying legal requirement without ever building a ‘backdoor’.

Apple said the decision to withdraw ADP in the UK left them “gravely disappointed”. There was, however, an important disclaimer. Apple only stopped allowing new UK users to turn on Advanced Data Protection.

Apple:

For users in the UK who have already enabled Advanced Data Protection, Apple will soon provide additional guidance. Apple cannot disable ADP automatically for these users. Instead, UK users will be given a period of time to disable the feature themselves to keep using their iCloud account.

I wonder whether Apple will actually lock users out of their accounts if they don’t turn off ADP or whether they’ll quietly not enforce it like with Emergency SOS via satellite.

Cohen:

In July 2026, Apple lodged a fresh complaint at the Investigatory Powers Tribunal, which became public the following month. Then, on the 11th of September 2026, U.S. Senator Ron Wyden (a Democrat) and Republican Congressman Warren Davidson called on the UK’s Investigatory Powers Tribunal to open up its proceedings concerning Apple’s encrypted-data dispute.

[…]

On the 17th of September The Daily Telegraph reported that Apple had asked the Investigatory Powers Tribunal to remove restrictions that gag them from confirming the existence of the reported TCN.

Persistent Ads in iOS Settings

Alex Blake (Hacker News):

The ‘ads’ in question appear in the Settings app in iOS. They can be found near the top of the iPhone’s display and promote several products to the user, including paid-for iCloud+ storage, free trials for services like Apple Music and Apple TV, and the AppleCare+ extended warranty.

Infuriatingly for iOS users, the only way to disable these promos is to either let them expire — which in many cases could take weeks or even months, leaving a persistent notification badge on the Settings app in the meantime — or pay for the service being offered. There is not always a “dismiss” button to shoo them away for good, and when there is, some people have reported that it doesn’t seem to work.

“Prepare to Ship” Battery Drain and Limit

Juli Clover:

The iPhone 18 Pro Max has a battery capacity over 20 watt-hours, which means there are additional shipping requirements. If an iPhone 18 Pro Max needs to be shipped somewhere, its maximum battery capacity has to be limited through firmware.

[…]

Customers who need to ship the iPhone 18 Pro Max for repair, trade-in, or other purposes have to use a new Prepare to Ship feature. Prepare to Ship discharges the battery to below 20Wh and sets a charge limit so the iPhone stays below the threshold during the shipping process.

Laptops, of course, have larger batteries, but they aren’t affected because each cell is below the limit.

Carbon Copy Cloner 7.2

Mike Bombich:

I remember seeing this one way back in Big Sur; you’d create a perfectly functional bootable copy of the system, but it wouldn’t show up in the Startup Disk Preference Pane. Apple ultimately resolved that issue in macOS Monterey, but now we’re seeing it again — unfixed in the Golden Gate release candidate.

The new CCC has a workaround, as does SuperDuper.

CCC 7.2 introduces a hybrid approach for bootable backups: as long as the source and backup OS versions are the same, CCC will update the backup incrementally without requiring any task configuration changes. This new approach will make many of the CCC-specific features available for bootable backup tasks, e.g. backup versioning, Quick Update, insight into what changes were made to the source between events. For the long stretches of time where your Mac’s OS isn’t getting updated every day, now you can enjoy the full benefits of the CCC backup solution.

These are great benefits for anyone that requires a bootable backup, but this isn’t a panacea. If the OS versions don’t match, the destination (and all backup versions) still must be erased and recloned; again, to offer the most reliably-bootable copy of macOS. We made improvements here, too. By default, CCC will ask for your approval before erasing the destination — this allows you to schedule your backup task without the fear of the backup getting automatically erased whenever the source OS is updated. That also allows you to retain the option of downgrading the source volume’s macOS, which you might want a day or so to assess.

Shop Different

HarperCollins (Amazon):

When Steve Jobs hired Ron Johnson to create the Apple Store in 2000, conventional wisdom said that the internet would put stores out of business. By the time he left Apple in 2011, Johnson and his team had created the most respected and profitable retail stores in the world. And even then, skeptics were still predicting the death of physical retail.

In Shop Different, Johnson reveals how it happened: how he earned Jobs’s trust, how they developed a vision for a store that would win not by selling but by serving, and how he convinced Jobs that the store’s service philosophy should be rooted in something as intangible as love. Johnson then gives readers a new look at Apple’s ascent to the most valuable company in the world; offers an inspiring vision for a future in which retailers win on connection, service, and experience; and shares an honest look at what leads to success—and what can follow.

I enjoyed this interview that Jeff Benjamin and Fernando Silva did with Ron Johnson.

Airmail 26.037

Today, Apple sent me an e-mail about the Airmail Mac e-mail client:

Thank you for subscribing to Airmail Pro Yearly. We wanted to let you know about an upcoming change to this subscription.

The developer, Bloop S.R.L, is raising the price of this subscription from $9.99 per year to $49.99 per year.

This is a big increase in percentage terms, but the new price is actually not out of line with subscriptions for other e-mail clients these days. There remains a free version that supports a single mail account.

They recently added an MCP:

Airmail now connects to AI assistants like Claude, Codex, and other compatible chatbots — so you can manage your email just by asking, in plain language.

Ask your assistant to find messages, summarize long threads, draft replies, tidy up your inbox, and organize folders. Airmail stays in control: everything runs on your Mac, and you decide what the assistant is allowed to do.

Most relevant to recent discussions here: does Airmail access Exchange accounts via the moribund EWS or the newer Graph API? They told me that it does not currently support Graph but that they will add that in a future update.

SpamSieve 3.3.2

SpamSieve 3.3.2 is an update of my Mac e-mail spam filter that improves remote training, can export more rule information, and improves uninstallation, help, and more. The most significant news is that Microsoft has changed plans again. They will no longer be preventing users from continuing to use Legacy Outlook and in fact will keep it available for download as part of the combined Outlook app. This gives more time to adapt to their change in plans for AppleScript. Exchange (EWS) support remains an issue. Microsoft is still planning to cut off Legacy Outlook users, and Apple has yet to announce when Mail will support Graph. So far, I’ve not heard that it’s enabled in the macOS 27.2 beta.

We’re participating in a seasonal festival of artisanal software called SummerFest. For a limited time, you can get a 25% discount on new purchases of SpamSieve, EagleFiler, and other top Mac apps from our indie developer friends.

Golden Gate Liquid Glass

Andrew Cunningham:

The Golden Gate update to Liquid Glass solves a fair number of the most common criticisms through both design changes and customizable settings. It doesn’t fix everything, and the changes are primarily iterative—if your quarrel is with the overall design direction, this update won’t help you.

[…]

The net effect of all of Golden Gate’s design changes isn’t huge, and Golden Gate still looks more like Tahoe than like any previous version of macOS. Some controversial decisions remain in effect, like putting any non-squircle icons into “squircle jail” so they can think about what they’ve done.

[…]

But based on reactions I’ve seen during the betas, I expect these tweaks will be just enough to quell the loudest complaints, at least for people who were using Liquid Glass as an excuse not to upgrade.

It’s better than before but doesn’t go anywhere near far enough. Every time I do testing on a pre–Big Sur Mac (or even on Sequoia) I get sad about what we’ve lost.

Howard Oakley:

The most obvious improvement in Liquid Glass from Tahoe is the change from a choice between Clear or Tinted to a replacement slider. This also features one of the new Easter Eggs, a beautifully rendered image of Clarus the Dogcow.

[…]

Quite why Apple has pushed this decision so far forward I don’t understand, though. As with the previous options, for this slider to work, Accessibility settings like Reduce transparency must be turned off, on the basis that you can’t have too much of a good thing.

Basic Apple Guy (Bluesky):

Nature is healing

Jesse Grosjean:

I do appreciate some of the fixes in macOS 27. But this work ain’t done yet. What is even happening in this inspector[…]

TanglyConstant9:

macos 27 system settings graphical bug

Jeff Johnson:

Everyone is going to pretend that Liquid Glass is fine now, “nature is healing”, and such total bullshit.

The Overton NSWindow had shifted so far that nobody even knows what’s good and bad anymore.

macintog:

I skipped macOS 26 entirely out of utter contempt for the criminally bad UI. I’ve lived on macOS 27 since the first Developer Beta. It’s in great shape, the most mature x.0 in many years (unsurprisingly considering they began its development two months earlier than usual).

Jeff Johnson:

The widget only appears only when hovering over a certain area, and the only item in its popup menu is Show App in Finder…

Jim Chaffin:

Opened the new version of Mail in the just ‘upgraded’ Golden Gate and immediately went searching for a fix! Included is what the Mailboxes Sidebar looks like in my few months old iMac.

Benjamin Mayo:

I know they did it purposefully to add more contrast to selected items, but I don’t really like the changing font to bold on Golden Gate sidebars. It changes the text size which looks awkward, particularly when it has to truncate.

Steven Woolgar:

Even with Apple’s OS 27 release, Liquid Glass is the software equivalent of super gluing tacky gold gewgaws all over the place.

Peter Witham:

I don’t think Apple did enough testing on Notes in Golden Gate, those group and sort options are empty?

Dominik Wagner:

Oh, what fresh hell of indistinguishable came this new preview app icon’s choice?

Jeff Johnson:

They totally fixed Liquid Glass on Golden Gate.

Rui Carmo:

And, yes, liquid glass is still there. I don’t care about how many sliders they put in, every time I see that I am reminded that if they needed to add it, they blew it.

Previously:

Update (2026-09-23): Kevin C:

I had the run the betas in a VM, and thought the UI was a great improvement over Tahoe. However, it left me unprepared for the new bright edge highlights around buttons and input fields, etc. on HDR displays when actually updating my MacBook. I was glad I could fiddle around with BetterDisplay and disable XDR settings, which removed them. But I would prefer that an accessibility setting like Reduce Bright Effects considered them to be bright enough to reduce.

Xcode’s New .xcproj Files Are JSON

Apple:

Xcode now supports a JSON-based project format (.xcproj) that’s more readable, merge-friendly, and easier for coding agents to edit. Enable it in the file inspector. Projects using .xcproj also open in earlier versions of Xcode 27. Learn more in Updating your Xcode project configuration file format.

Fatbobman:

[The] new project.xcproj caught my eye. What it replaces is project.pbxproj, the build graph inside the .xcodeproj bundle, not the bundle itself.

[…]

In the age of agents, the drawbacks of pbxproj are amplified further. A great many IDs carry both object identity and cross-references, so an agent modifying a project usually has to locate the right object in a flat table, then update several mutually referencing places in step, all while trying to keep the serialized output faithful to Xcode’s conventions.

[…]

From a flat ID table to a tree that mirrors the UI: instead of dumping everything into objects, it unfolds into structures like files / targets / build-settings, so diffs look closer to the operations you actually performed in the interface;

The direction of relationships is reversed: a file can declare which targets it belongs to via target-membership, so adding a file no longer means editing several mutually referencing places at once;

Simon B. Støvring:

Developers have been screaming for a friendlier Xcode project format for years. I’m one of them.

Tony Arnold:

I’ve been waiting for something like this for most of my career! 🎉

Rob Napier:

It does feel like another case of “we’ve quickly done a thing to help AI that we’ve been unwilling to do for years to help humans.” I’m seeing that happen across the industry.

It is very welcome and appreciated, and lots of thanks to the teams involved. It’s also frustrating that it took “it can help AI” to make it happen.

Apple:

xcode-project-format is a Swift library for reading, writing, and manipulating Xcode’s JSON-based project.xcproj format. It models the format as a rich set of value types nested under a single namespace, XCSchema, so consumers get precise, typed access to a project’s structure instead of hand-parsing JSON.

The goal is to give the ecosystem a shared, accurate model of the Xcode project format — so tools like generators, linters, verifiers, and validators don’t each have to reverse-engineer the format from scratch.

Helge Heß:

Didn’t most people switch to local SPM projects anyways? Those are the new xcproj that have to be replaced with sth sensible 🙃

Fatbobman:

What the community has actually been waiting years for is a project manifest along the lines of Package.swift: something written by people, read by people, and reviewed by people, rather than a more modern encoding of the IDE’s internal database.

Previously:

Update (2026-09-23): John Gruber:

The old .pbxproj project format was not XML; it was an old NeXT-style “ASCII” property list — a file format that is surprisingly JSON-like considering that it predates not only JSON, but JavaScript (JSON = JavaScript Object Notation).

Jumping to 27.2

Joe Rossignol:

Apple just seeded the first beta of iOS 27.2 to developers for testing. Yes, you read that correctly: iOS 27.2, not iOS 27.1.

[…]

Apple previously announced that the iPhone Duo will ship with iOS 27.1, which means that software version will contain all sorts of references to the device hidden within the code. If an iOS 27.1 beta were to have been released today, it could have spoiled some smaller iPhone Duo details that did not make it into Apple’s event.

John Gruber:

So, putting beta releases aside, we’ll see the versions hit the public in numeric order:

  • All OS 27.0 releases: two days ago.
  • iOS 27.1: October 23, exclusively on the iPhone Duo.
  • All OS 27.2.0 releases: probably in late October, after the 23rd, but with the Duo remaining on its own 27.1 branch.

[…]

Maybe Duo convergence will wait for 27.3, but I think it’ll be a 27.2.x update.

[…]

Something similar happened back in 2010 with the original iPad, which launched in April 2010 running what was then still called iPhone OS, version 3.2.

Steve Troughton-Smith:

iPhone Duo being completely disconnected from the iOS update cycle is very likely why its software features didn’t leak — wouldn’t surprise me if iOS 27.1 is unique to that device, and the rest of the lineup skips it (or gets some security updates, iOS 27.1 in name only)

Xcode 27.2 Beta Release Notes:

The iOS SDK and simulator support for iPhone Duo will be available later this month in an upcoming release of Xcode 27.1.

John Gruber:

Developers wanted this SDK a week ago. And when day one preorder buyers start using their Duos on October 23, they’re going to wish Apple had shipped this SDK last week too.

Der Teilweise:

What annoys me about Apple releasing Xcode 27.2 Beta 1 before they release Xcode 27.1 Beta 1 is that there was absolutely no need to release 27.2 Beta 1. They could just have postponed it. Nobody asked for 27.2 Beta 1. What version are we supposed to use? One for releasing, one for Duo, one for fun?

Apple Reference Image

Apple (Hacker News, MacRumors):

Our solution hinges on splitting the Apple Reference Image process into two phases: creating a secure digital negative, and developing that negative into a reference image. Each phase receives our strongest protections.

[…]

Apple Reference Image provides both a lower bound and an upper bound on capture time from Apple’s cryptographic timestamp service, and we guarantee the photo was taken between the two bounds. On a regular heartbeat, the device requests a cryptographic timestamp token, and retains the most recent one it has received. Globally this happens on average every 15 minutes, though the interval depends on local network conditions. This provides a proven lower bound timestamp for the photographic capture. After capture, the device requests a second timestamp to use as an upper bound, and both timestamps are embedded and signed with the sensor data.

[…]

When the user chooses to create a reference image, the device uploads the digital negative to PCC, which runs the processing steps needed to render the image — including demosaicing, tone mapping, and compression — in a highly secure, private, and verifiable environment. Experts can verify that PCC doesn’t alter a digital negative during development: they can examine the software that does the work.

[…]

Finally, as no security system is perfect, we created a revocation system that can revoke individual photos, as well as all photos from a specific sensor.

[…]

We built Apple Reference Image to avoid using an explicit, public credential for photographers, and to avoid even implicit public association between different photos taken by the same sensor. The final reference image is instead signed by Apple’s signing service, after validation by PCC.

CarPlay in GM Trucks

Jonathan M. Gitlin:

GM made the decision to drop Apple CarPlay and Android Auto phone casting from its newer EVs, and it’s one we’ve been pretty critical of. Although the automaker told us it made that decision in order to offer a better, more unified experience to its customers, that may well have changed: here, customers still have the choice to just cast their phone to the center screen.

And it has done a better job of integrating CarPlay and Android Auto into the experience, putting the casting apps in a large window or tile that takes up most but not all of the infotainment screen. To the left is another card that allows you to access other native apps, like towing or music (although you can still have CarPlay as the source for that native music app, should you start feeling a little Inceptionish). Porsche took a similar approach to working with, rather than against, users who enjoy CarPlay, and this looks like a welcome step from GM.

GM’s spokesperson wouldn’t be drawn on whether this means we’re going to see a corporate retreat from the previous stance on EVs, but I will note that the press release it sent Ars does say that the system was built “as a single scalable foundation across electric, gas and diesel-powered vehicles, it transforms time spent behind the wheel into an effortless, personalized journey,”—emphasis mine.

Matthew Haughey (via John Gruber):

The car industry accidentally did something I’ve always wanted to see, which was to release basically the same car under two brands and models, with one major consumer-facing difference. It’s kind of remarkable how good of a experimental design this is, since the performance and driving characteristics of both cars are identical, but drivers in one model get a major phone integration the others do not.

[…]

For the years these cars were sold together, the Honda outsold the Blazer by 43%, 73%, and 166% in each time period. Today in 2026, people are buying a Honda Prologue over one and a half times more often than the Chevy Blazer EV the Prologue is based on.

Marco Arment:

My favorite CarPlay feature is when it’s reading a text message to me and I go to tap the “Done” button and it suddenly turns into a “Call” button underneath my finger and I have to wait for all of the animations to finish before I can actually end the call and then I wonder (a) did the person notice that I called them for a few seconds and (b) do I need to explain that now and (c) are they going to call me back now and (d) HOW DID THIS INTERFACE EVER SHIP oh my god

Previously:

Update (2026-09-22): Joe Rossignol:

All in all, GM really wants you to know that it is committed to ditching the extremely popular feature that you probably want in your next EV.

It will only offer the choice in gas vehicles.

iPhone 17 Model Popularity

David Smith:

Here’s the 17 family data as a percentage of overall usage for Widgetsmith.

Generally they followed the usual adoption pattern, and overall did very well ending at around 20% of total usage.

With the exception of the Air really struggling to find market share. For comparison the 16 Plus ended its first year at around 1.4% (vs the Air’s 0.3%).

Matt Birchler:

This works out to about 6% of my iPhone users using the iPhone Air, or about 20x more proportionally than David's more mainstream app. Honestly, the numbers are pretty striking here, with David showing a pretty even split between the iPhone 17, 17 Pro, and 17 Pro Max, slightly decreasing in that order. Meanwhile, almost half of my users are on the Pro Max, another quarter are on the Pro, and the 17 is neck and neck with the Air. Clearly, my customers lean more enthusiast and are higher end buyers on average.

Nick Heer:

The apparent unpopularity of the iPhone Air is not what caught my eye. Instead, it is the percentage of iPhone 17e users: 0.5% of Widgetsmith users, and something like 1–2% of the total iPhone 17 generation in Birchler’s.

The iPhone 17e hasn’t been on sale for as long, though.

John Gruber:

In the entire year since the iPhone Air was announced, I’ve never seen Apple advertise it. No billboards, no commercials. It raises a chicken/egg question: did no one buy it because Apple didn’t market it, or did Apple not market it because no one wanted it?

[…]

But the shame of these low iPhone Air sales reminds me, very much, of the late great iPhone 12 and 13 Mini — also a truly great design, also terribly disappointing sales numbers.

Opting Into Training Siri AI and Apple Foundation Models

Amber Neely:

A new section in the iOS 27 privacy policy shows that Apple has reversed its stance on using customers’ data to train its AI models. Previously, the company assured customers that it had no need for customer data, and would figure out how to make Siri AI work well without it.

Apple maintains that it “takes steps to ensure that personal data is not stored or used by Apple.” But as Heise points out, and Apple has said in the terms of service for a few years now, the audio material may be listened to by Apple employees after anonymization.

[…]

It also admits that data collected may be reviewed by “review personnel.” It is unclear if “review personnel” are Apple employees or a third-party company contracted to read conversation transcripts, as it has historically been.

Chance Miller:

Starting today, when a user enables Siri AI, they will see a setup screen asking whether they want to opt in to “improve Siri and Apple Intelligence,” with two options: “Share Audio and Text” or “Not Now.”

[…]

What’s important to note here is that nothing is changing about the type of data Apple collects if you opt in to this setting. What’s changing is that Apple will now use the data to train and refine its Foundation Models, as well as Siri and Dictation like before.

nunez:

iOS 26 had a toggle you could select to disable all Apple Intelligence features.

That toggle was removed for iOS 27. Every AI feature has to be turned off individually.

Xcode 27

Apple (xip, downloads):

Xcode 27 includes Swift 6.4 and SDKs for iOS 27, iPadOS 27, tvOS 27, watchOS 27, macOS 27, and visionOS 27. Xcode 27 supports on-device debugging in iOS 17 and later, tvOS 17 and later, watchOS 10 and later, and visionOS. Xcode 27 requires a Mac running macOS Tahoe 26.6 or later.

Peter Witham:

Is this new in Xcode 27? Pretty sure it as and I approve whole heartedly! I really hate setting up Xcode settings more than once.

Christian Beer:

Building with Xcode 27 doesn’t work because of some intransparent XCStrings error… and I even can’t check with Xcode 26 anymore because Apple decided to not let me run it on macOS 27…

Steven Woolgar:

After all these years Apple has finally broken cmd-e in Xcode 27.

Previously:

Update (2026-09-18): Jesse Squires:

Xcode 27 seems to have broken UI appearance vs Editor appearance. They used to be separate settings.

For example, previously, the app could be light mode while the editor theme was dark.

But now, you choose a dark editor theme and the whole app goes to dark mode.

I hate this.

Me, too.

Update (2026-09-22): Wade Tregaskis:

Yesterday I tried doing the 15.8 update (from 15.7.9) inside one of those VMs. It hanged, midway through the post-reboot install process. I had to ‘power-cycle’ the VM. Which booted it back into 15.7.9, except… shockingly slow. Like, I can watch the individual elements of the GUI render like it’s the 1980s again.

I eventually figured out that my 16 GiB VM could only “see” 1.75 GiB of RAM, and was therefore swapping all to hell.

[…]

In hindsight, the simplest solution might be – I have not tested it – to just run:

sudo nvram -d boot-args

That should clear the boot args, eliminating whatever insane stupidity Apple’s updater enacted there.

me22 (via david_blanchard):

Apple’s camera raw support seems to be broken here since updating to macOS 15.8.0.

Update (2026-09-23): Brian Webster:

I can corroborate there being a problem with RAW files on macOS 15.8. I’ve had two customers run into problems trying to copy RAW images with PowerPhotos, it appears that photolibraryd ends up deadlocked somewhere in the RawCamera library, and you have to kill it to get things moving again.

iOS 26.7 and iPadOS 26.7

Juli Clover (iOS/iPadOS release notes, security, no enterprise, no developer):

According to Apple’s release notes, iOS 26.7 includes security fixes, but it does not have any other features.

Apple will eventually show iOS 27 as the main update for the iPhone, but that likely won’t happen for a few weeks. Users who want to stay on iOS 26 for the time being can do so by opting for iOS 26.7 instead of iOS 27 .

macOS 27 Golden Gate

Apple (release notes, security, enterprise, developer, full installer, IPSW):

Andrew Cunningham (Hacker News):

Generative AI is unavoidable if you install macOS 27 Golden Gate. I’m being very literal: There used to be a toggle you could hit if you wanted to turn off Apple Intelligence and delete the gigabytes’ worth of AI models it would download to your disk, and now there isn’t. Apple Intelligence defines the Golden Gate release, in everything from its marketing to its features to the chips it runs on to the amount of space it takes on your disk.

[…]

More impressively, for apps that support it, the iPhone Mirroring window can now be resized dynamically while running apps. Apps will resize themselves to take up all the available space, and once the window is wide enough, you can even take advantage of multi-column iPad-style views for the apps that offer them.

[…]

For most Mac users, though, Golden Gate is a no-brainer update with few major downsides. It won’t hurt anything to wait until the 27.1 or 27.2 release if you’re already on macOS 15 Sequoia or macOS 26 Tahoe and you’re not in a hurry.

Juli Clover:

macOS Golden Gate: 10 Features to Try First

Paul Haddad:

Did Virtualization under 27 get hit with the slow stick? Trying to run a Mac VM on my M1 Ultra and it feels basically unusable. Getting Intel flashbacks.

Jeff Johnson:

In System Settings Privacy & Security, the Accessibility pane has been renamed to Device Control and Data Access.

Avi Drissman:

Have you been noticing that, starting with macOS 27, you have been consistently failing to SSH to a remote machine? Is it the case that the remote machine’s password ends with a shifted character?

There is a new setting: “Shift Return sends Meta Return” under Settings > Profiles > (profile) > Keyboard. This setting (enabled by default!) will cause a shift-return keypress to insert an ESC before the return is sent.

Ever since updating to Golden Gate, my Mac now periodically makes a scratchy paper alert sound. No idea from what.

Chris Pepper:

Hopefully 1Password will upgrade v7 for OS 27 compatibility, but I can’t count on them fixing bugs in v7 — they’re pushing users to v8.

I found a ‘fix’ for this crash, but that command didn’t work (even after enabling Full Disk Access for Terminal so it could actually execute), and isn’t available on iPhone or iPad.

Nicholas Riley:

Golden Gate status: wow, the new menu extra/Control Center area is rough. Not just unpolished UI behaviors but multiple crashes. Hidden Bar is no longer functional and none of the replacements I found actually worked, while having about 100 features I don’t want.

System keyboard shortcuts also seem to be an area that weren’t well tested. My preferred screenshot shortcuts were ignored until I opened that section of System Settings, and some Siri thing created a conflict with Spotlight so I get both of them when I press ⇧⌘Space.

macOS golden gate is still shockingly terrible in unexpected ways.

Steve Troughton-Smith:

I’m no math expert, but I’m pretty sure this doesn’t add up to anywhere near 16GB. I’ve only started seeing this dialog in the release build of macOS 27.0, despite running the betas all summer, so clearly there are some ghosts in this build

Mario Guzmán:

Okay… how do you

  1. make everything super huge like the text and pictures… while
  2. having way more empty space than you need AND STILL have to
  3. truncate your text labels?

8 of the 9 text labels are truncated.

Can we please have designers who know how to design for DESKTOP software and NOT magazines/print?

Jeff Johnson:

There are a surprising number of behavioral bugs in Golden Gate. It's not just a superficial update. Apple is basically breaking AppKit.

Mark Lilback:

I reported a bug to Apple in May, found while building Alcove. Two OS releases later it still isn’t fixed. It has gotten worse with each one.

[…]

On the betas the whole window went blank after the Cmd-Tab: sidebar, content, detail pane, status bar, everything but the toolbar. On the 27.0 release it usually doesn’t wait for the Cmd-Tab. In 5 of 6 clean launches the window came up with only the toolbar drawn. Cmd-Tabbing away and back doesn’t fix it. It moves the sidebar’s first row up under the traffic-light buttons and leaves the rest of the window empty[…]

tvOS 27

Juli Clover (no release notes, security, developer):

tvOS 27 features a redesigned Podcasts app, options for larger text and customizable subtitles, and a more responsive Control Center. AirPlaying to an Apple TV from another Apple device is faster, apps open quicker, and animations are smoother.

tvOS 27 works on the 2nd and 3rd generation Apple TV 4K models, and it drops support for the Apple TV HD and the first-generation Apple TV 4K.

Previously:

Update (2026-09-23): Steven Aquino:

Back in late May, I wrote about tvOS 27’s support for larger text sizes. […] After installing tvOS 27 on my A15 Apple TV, I immediately made a beeline to Settings > Accessibility > Text Size and spent a few minutes playing around with the larger text setting. As you’d expect, the UI for it is exactly what you’d see on iOS or iPadOS: a horizontal slider with notched intervals, with text overhead showing the adjusted size.

[…]

In the TV app, for example, using large text has material effects on, say, show descriptions and metadata. This is helpful because I’ve always struggled to read this information without physically walking up to the TV screen itself. On the other hand, I’m guessing third-party developers need to support the new API; in my testing, apps like Netflix and Pluto TV don’t (yet?) support larger text.

audioOS 27

Juli Clover (no release notes):

HomePod Software 27 adds AirPlay improvements and support for AutoMix when listening to Apple Music.

Ryan Christoffel:

AirPlay improvements may sound like a minor change, but in practice they can make a big difference in connecting quicker than ever to your HomePod. Using the iOS 27 beta, I’ve been pleasantly surprised by how fast and easy it is now to switch playback to and from my iPhone and HomePod.

[…]

There’s no Siri AI available in HomePod 27.

Golden Gate Release Candidate

Juli Clover:

The release candidate is the final version of macOS Golden Gate that developers and beta testers will get before the software sees a public launch.

Joe Rossignol (Reddit):

Apple this week announced that macOS 27, also known as macOS Golden Gate, will be released to all users with a compatible Mac on Monday, September 14.

iOS 27, iPadOS 27, watchOS 27, tvOS 27, and visionOS 27 will be released on the same day.

Jeff Johnson:

I would like to note two bugs that I reported during the beta period that remain unfixed in the release candidates, and barring a last minute miraculous reprieve, will remain unfixed in the public releases on Monday. This is disappointing, because I thought the point of the betas was for Apple to fix the bugs found by beta testers. While these two bugs are not destructive—do not involve data loss or security issues, for example—they nonetheless did not exist in iOS 26 and macOS 26, so in this respect, Apple’s updates are making their software worse for users.

[…]

The AppleScript run by the test app requires Automation permission, so macOS shows a permission prompt. […] It actually doesn’t matter whether you select Allow or Don’t Allow! […] Either way, just selecting something in the automation permission prompt seems to trigger the bug, causing macOS to wrongly consider the app to be running in the background.

Paul Kafasis:

Unfortunately, Apple’s forthcoming tvOS 27 and HomePod OS 27 updates contain a critical bug that prevents Apple TVs and HomePods from playing AirPlay streams sent by Airfoil. If your devices update to the OS 27 versions, Airfoil will no longer be able to stream to them.

Developing for iPhone Duo

Craig Hockenberry:

It looks like Xcode 27.1 is needed to test the iPhone Duo resizability - and that hasn’t been uploaded yet.

Jordan Morgan:

Cupertino and Friends™️ dropped six new videos over developing, designing, and crafting great apps for the nascent device:

  1. Design for iPhone Duo
  2. Prepare your app for iPhone Duo
  3. Raise the bar with iPhone Duo
  4. Strike a pose with adaptive layouts on iPhone Duo
  5. Leverage multiple displays and scenes on iPhone Duo
  6. Build a great camera experience for iPhone Duo

Nathan Manceaux-Panot:

In the Duo dev video, they describe how text buttons can’t be moved to the new vertical sidebar, as opposed to icon buttons.

I wonder if that’s one of the reasons Liquid Glass pushed hard for icon buttons, even though these are harder to understand; they make the vertical layout possible at all.

Nico Reese:

Totally confusing to me how the toolbar is ordered completely different between both modes here.

Dennis Oberhoff:

I think the problem with the iPhone Duo for developers is mostly that it does not create any new opportunities in the form of a new market or a new audience.

Apple writing example code in Objective C, in 2026. They are REALLY desperate for developers to support this device.

Natalia Panferova:

On iPhone Duo, navigation controls, toolbar actions, and tabs can move into a shared vertical bar along the edge of the display, leaving more vertical space for content. Apps built with the iOS 27.1 SDK get this adaptation through standard containers such as NavigationStack, NavigationSplitView, and TabView. We continue to declare toolbar actions in their usual placements, and SwiftUI determines how to present them in the current context.

Imthaz Ahamed:

I was going through the iPhone Duo specs and realised the inner screen has a different pixel density to the outer screen. The inner 7.6-inch folding display runs at 1878×2670 and 430 ppi, while the outer 5.4-inch display runs at 1398×2034 and 460 ppi.

Jesper:

The iPhone Duo remains interesting, and is clearly a technical tour-de-force that is the outcome of deep thinking about what a foldable phone can be. But the things that sparkle in my mind when I consider it is just the details. They are very important details that yield a noticeably different product, but they are sprinkles on top of a downward slope in user interface design at Apple that does not care any longer about what users or developers want. All that's important is for this year's device to uproot fundamentals and demand that everyone conform to an arbitrary new intuition.

iOS 26.6.2 and iPadOS 26.6.2

Audio Intelligence

Apple:

Audio Intelligence is a brand-new class of Apple Intelligence features that use the microphones of Apple Watch, the power of Apple silicon, and on-device and cloud-based AI models to help you detect sounds, identify music, and stay present and engaged — all while protecting your privacy at every step.

Hartley Charlton:

  • Siri Recap: Uses ambient listening to generate high-level notes from conversations, such as takeaways from a team meeting or a parent-teacher conference, producing an Apple Intelligence-generated title, summary, and key points reviewable in the Siri app.
  • Live Rewind: Lets users “go back in time for 15 seconds,” transcribing and displaying what was just said in a conversation with a double press of the Digital Crown.
  • Shazam: Automatically identifies music playing nearby and surfaces the song title and artist on the Music Recognition widget in the Smart Stack.
  • Sound Recognition: Brings sound alerts to Apple Watch for users who are deaf or hard of hearing, listening for sirens, alarms, doorbells, a baby crying, and more, even when their iPhone isn’t nearby.

Lily Hay Newman:

Apple is emphasizing that all of them are built to prioritize privacy and security using the extensive infrastructure the company has developed to protect its other Apple Intelligence and Siri services. As more and more of these types of features debut, though, the audio intelligence announcements are a reminder that AI-powered tools are becoming increasingly universal in all areas of computing and life.

“These features do not create or store audio recordings, and raw audio used for processing is completely inaccessible to the operating systems, apps, the user, or Apple,” the company wrote in a report shared with WIRED.

[…]

Apple emphasizes that its on-device capabilities for Apple watches have expanded thanks to the company’s new S11 chips. The chips include a special memory-protected space that Apple calls the Secure Exclave. Designed specifically for sensor data, the exclave is an isolated buffer that is inaccessible to the rest of the operating system where Apple Watch can hold and process audio data in a protected space.

[…]

To try to mitigate blatant privacy violations, Apple says that the watch produces an audible chime when a watch owner initiates a Live Rewind transcript to alert other people in the area—even if it is on silent mode or paired with headphones. And the features are built to omit or filter out potentially identifying information about speakers. But the sheer scope and breadth of the tools is extremely noteworthy.

Zac Hall:

If you want to really take a deep dive on privacy and the new features, Apple has published an 11-page privacy paper that goes even further.

Previously:

Update (2026-09-11): Dr. Drang:

Ron Huang introduced a couple of features of the Series 12 and Ultra 4 that struck me as both disturbing and possibly illegal. They certainly seem at odds with Apple’s commitment to privacy.

[…]

I’m sure Apple will argue that there’s no privacy issue because the recordings aren’t being saved. But if there’s a transcription, isn’t that a type of saving?

And then there’s the question of legality. A great variety of law, both in the United States and across the world, concerns the recording of electronic and in-person conversations. I’m sure Apple has considered this, but I have to think some jurisdictions will frown on Live Rewind. If Apple has to defend it, that’s fine. What’s one more squadron of lawyers to Apple? But if an Apple Watch owner has to defend a transcription made innocently—made with Apple’s encouragement, in fact—that seems like an unfair burden. Maybe Apple should indemnify all future Watch buyers from privacy-related legal action.

[…]

The hoops Apple jumped through to avoid certain words is pretty funny. […] You think your watch records the audio around you? No no no. The audio flows into the Secure Enclave, and flowing is definitely not recording because it’s a different word.

Juli Clover:

Live Rewind and other Audio Intelligence features do not generate audio recordings. Audio flows into the Secure Exclave, is processed, and then deleted.

According to Apple, Live Rewind text snippets “disappear permanently” from the Apple Watch approximately 30 seconds after the Apple Watch display dims, unless the info is saved to the Siri app.

Nick Heer:

But good luck explaining that to anyone around you after you read back an exact transcript of what they just said. Apple says they should be sufficiently notified Live Rewind is active because “an audible chime plays from the speaker on your Apple Watch, even if your Apple Watch is on silent or you have headphones connected”, plus the watch plays an animation, but it is not clear to me when this happens. It is not shown in Apple’s video. The impression I get is that Live Rewind is always running in the background and these notifications are only played after you double-click the Digital Crown to look at the text.

This feels like a glimpse of how Apple will market its inevitable wear-anywhere glasses product. I do not think it does enough to assuage privacy concerns. I think normal people will continue to react negatively when you tell them you have been passively recording them because, outside Silicon Valley, that is considered gross and invasive.

Saagar Jha:

I have to admit that the Siri Recap stuff all being “documented” using AI slop is really giving me confidence in the level of care that went into designing this feature

Matt Evans (Hacker News):

I’m frankly surprised Apple even went through with this feature at this time, considering the bans and backlash other AI-powered surveillance wearables are getting.

[…]

Apple is keen to evidence its trustworthiness, with on-device AI and Private Cloud Compute and an insistence that it doesn’t record or log audio and transcripts. However, if people think they’re being discreetly recorded without their permission, it’s possible Apple Watch wearers could experience their own slice of the abuse hurled at Meta Glasses wearers.

Dan Sugalski:

I… y’know, Betteridge’s law does, as always, apply.

Glenn Fleishman:

Given that Apple has to warn of this, it’s the surest sign the features shouldn’t be released in this form. Apple repeats the form of the warning I see regularly at my gym… but apparently it isn’t heeding it.

Jack Brewster:

Just called my HSA provider and upfront they say that calls may be recorded and transcribed by AI and then provide no means of opting out. So of course the person who finally answered says I have to give my social to verify my identity.

Update (2026-09-17): See also: Accidental Tech Podcast.

John Gruber:

I was walking home from dinner here in Philadelphia a few weeks ago with a friend visiting from out of town, talking about this, and he stopped midway between the restaurant and my house and asked me to count how many cameras we were on at that spot. I think we counted seven or eight. Who knows how many we missed? I’m not saying that’s good or bad, it’s just the world today. So too it’s soon going to be with personal devices recording audio. This is inevitable. I’m glad to see Apple ship features like this early, with pretty limited scope, to provide good examples before other companies ship devices that record and save audio continuously throughout the day. I think it’s better for Apple to lead with privacy-minded versions of ambient transcripts and AI-generated conversation summaries than to follow after other products have hit the market with all-day recordings and whole-life transcripts.

[…]

I shouldn’t be able to hide my iPhone on or near someone’s desk, or in a conference room, or in a car, or anywhere else, to get Siri Recap summaries of conversations where I’m not present. Making this an Apple Watch exclusive feature avoids that. Thus, I think Apple Watch can be trusted to “listen” ambiently, all the time while it’s unlocked on the wearer’s wrist, in ways that even an iPhone can’t.

Wiley Hodges:

I applaud Apple’s decision to make Siri Recap, Live Rewind, and Shazam features opt-in. In the case of Siri Recap, they’ve taken the extra step of allowing you to schedule when and where the feature is active, allowing you to set parameters such as ‘never at home’ or ‘only between ten and six.’ This is the right way to treat a feature this sensitive.

[…]

So why do they creep me out?

[…]

Audio Intelligence appears to me to be the first case of a always-on feature with some of the qualities of surveillance we’ve seen in other products—an enduring record, an uncertainty on the part of others in the room about what’s happening—that also takes care to minimize the privacy harms that seem to be essentially intrinsic to such products. By doing their homework and showing us the receipts, Apple has taken fears of audio recording or even detailed after-the-fact transcripts off the table. But what they’ve left there is a set of questions about social and even legal norms and expectations. They’ve also created a potential problem for Apple Watch users in the form of a newfound suspicion that every word is being recorded unseen.

Health Sensing and Readyness

Apple (MacRumors):

The new Health Sensing System on Apple Watch Series 12 and Apple Watch Ultra 4 features new optical and electrical heart sensors, enabling higher-frequency heart rate and heart rate variability (HRV) measurements, a new readiness score, a more comprehensive Vitals overview with the addition of HRV, and an updated Heart Rate app.

[…]

Apple Watch Series 12 and Apple Watch Ultra 4 introduce readiness — a new feature that analyzes a user’s recent activity, vitals, and sleep score, and then provides a single 0-10 score each day with a clear, actionable recommendation: Recover, Pace Yourself, Ready, or Go For It. This helps a user decide how to take on their workday or tackle their training plan.

[…]

A new Longevity tab analyzes a user’s longitudinal health data for deeper insights into heart health, sleep, mental wellbeing, movement health, metabolic health, hearing, and nutrition. The tab includes Health Age, a new feature that uses Apple Watch data to show users how their metrics are tracking relative to their chronological age, informed by the best available science.

Kuba Suder:

I wonder how much of this new health stuff will work with older / SE watches… probably not much?

Previously:

Apple Watch Ultra 4

Apple (video, MacRumors, Hacker News):

Engineered with the new Health Sensing System and S11 chip, Apple Watch Ultra 4 delivers the most accurate heart rate sensing in a wearable, higher-frequency heart rate and heart rate variability (HRV) measurements, and a new readiness score to support athletes of all kinds. Apple Watch Ultra 4 also offers extended battery life to track outdoor workouts for up to 45 hours and the most accurate on-device GPS in a sports watch.

[…]

For everyday use, Apple Watch Ultra 4 now offers more than two days of battery life, up to 50 hours. In Low Power Mode, it offers up to 84 hours of battery life. Charging is now faster than ever: Just 15 minutes adds up to 18 hours of additional battery life.

[…]

The pedometer model has been completely redesigned with new machine learning algorithms and the S11 chip to provide more accurate distance measurements during indoor walk or run workouts, and more accurate step counts all day.

[…]

Apple Watch Ultra 4 starts at $799.

pilif:

The Ultra 2 was sold to me as the watch that can do Siri without network connectivity. That was very useful to me to leave reminders for stuff I think about while on a run without the phone.

3 years later, Apple releases the OS 27 versions and Siri got improved to the point where it can’t work on-device any more on said Ultra 2

So to get the feature back which I paid for and which was specifically used to sell me the device and which now has been taken away from me, I just have to… buy the next hardware generation?

And how long will that last before they decide to remove the feature again?

Does it still work offline in the EU?

Previously:

Apple Watch Series 12

Apple (video, MacRumors, Hacker News):

With the new Health Sensing System and S11 chip, Apple Watch Series 12 delivers higher-frequency heart rate and heart rate variability (HRV) measurements, which power an enhanced suite of health and fitness features including a new readiness score.

[…]

Apple Watch Series 12 is designed to be as individual as the person wearing it and is available in an array of beautiful finishes, including dark bronze, black, light gold, and space gray aluminum, and radiant gold and natural titanium. It is also available in a stunning ceramic material, in pearl white and night blue. Aluminum models now feature Ceramic Shield 2, which is tougher than any smartwatch glass and 60 percent tougher than the Ion-X of previous aluminum models.

[…]

Apple Watch Series 12 continues to offer up to 24 hours of everyday battery life and now offers up to 10 hours of battery life during an outdoor workout — 25 percent more than the previous model.

iPhone Duo

Apple (video, MacRumors, Hacker News, Slashdot):

Apple today introduced iPhone Duo, the first foldable iPhone. Opened, it is the thinnest iPhone ever, with a 7.6-inch inner display that provides a large canvas for viewing content, gaming, and multitasking, and a special nano-texture finish that minimizes glare for an unparalleled viewing experience. Closed, the 5.4-inch outer display delivers 90 percent of the screen area of iPhone 18 Pro in a compact, pocketable design. Both displays share the same aspect ratio, so content scales proportionally, ensuring visual continuity. iPhone Duo is built to last with an innovative hardware design and a precision hinge that offers a smooth, satisfying feel with every use.

[…]

The 48MP Fusion Ultra Wide camera — the same as on iPhone 18 Pro models — captures wider fields of view and enables macro photography, while the Center Stage front camera can automatically take photos and videos in any orientation, so users don’t have to rotate iPhone for landscape selfies. Upgraded Photographic Styles with new texture and grain controls let users further dial in their desired appearance and have more creative control over their photos. […] The foldable design with dual displays unlocks camera experiences that are not possible on any other iPhone.

[…]

Lock Screen controls, the Dock on the Home Screen, and app navigation and controls now appear on the side to maximize vertical space for content. When iPhone Duo is open, the display shows two Home Screen pages with Today View — a vertically scrolling list of customizable widgets — on the left. The status bar includes a circular, flexible system that nestles into the corner of the screen, showing relevant information like Wi-Fi, cellular strength, battery, and more.

[…]

The expansive display supercharges productivity, letting users do more at once with new multitasking capabilities. Split View allows users to open two apps side by side on iPhone for the first time.

[…]

iPhone Duo is available in star white and night sky, and starts at $1,999, or $83.29 per month for 24 months, in 256GB, 512GB, 1TB, and 2TB storage capacities.

I love the idea of the larger screen and how it can be balanced half-folded like a laptop, upside-down, or on the short side. The camera is better than I expected. The price is high enough to make me lose interest but perhaps not unreasonable if it can actually replace your iPad. My main concern is that the wide passport-style shape doesn’t look very comfortable to hold or keep in your pocket. It’s great that it can unfold, but the compact form factor is how most people will probably hold it most of the time. How well does the side Touch ID work if you’re left-handed?

In a joint interview with Tom's Guide and TechRadar, new Apple CEO John Ternus and marketing chief Greg Joswiak explained why the company waited until now to release a foldable, its design philosophy, and how it kept the iPhone Duo under wraps.

Kelly Guimont:

So here are my biggest unanswered questions from yesterday:

They said the iPhone Duo will fit in a pocket and is great for one handed operation.

Whose hands?

WHOSE POCKETS!?

Juli Clover:

The iPhone Duo does not include an Action Button, according to the device’s technical specifications page.

Tim Hardwick:

“The iPhone Duo’s under-display camera wasn’t placed in the top-right corner of the inner screen because of engineering difficulties,” said the leaker in a Weibo post this morning.

Dan Moren:

In the end, every Apple product—and probably every product—is a story of trade-offs. So, the thinking went, what will we give up to get the benefit of a small iPhone that unfolds into a larger iPhone?

The answer: some things, but less than I’d feared.

Dan Moren:

The company’s view is clear: the iPhone Duo, even when open in all of its glory, may evoke an iPad, but it is very much not an iPad.

[…]

It’s not an iPad that you fold up to put in your pocket. Or an iPad with a little iPhone glued to the front. It’s not running iPadOS. You won’t be installing or running iPad apps.

Tim Hardwick:

Apple’s iPhone Duo is the first iPhone that can run two apps side by side, but anyone expecting the sort of freedom that Split View offers on iPad might want to temper their expectations.

Matt Birchler:

I’ve been using Samsung’s latest folding phone that has a very similar form factor to what Apple just announced, and it’s gotten me accustomed to what the folding phone experience is. I personally very much like it, and it’s the most joy an Android phone has brought me in close to a decade. That said, I just watched Apple’s iPhone Duo unveiling, and it immediately made my Samsung phone feel behind the curve.

Rui Carmo:

Most of the UX we saw so far was both predictable and familiar to anyone who’s played with a Samsung Z Fold (Apple did not invent screen splits, app swaps or drag and drop), and so was the camera placement.

Ruffin Bailey:

Imagine an iPad mini in your pocket. This is my dream!

Well, you had me in the first half; not going to lie. It’s a dream, but not at $2200.

[…]

Now admittedly part of me doesn’t trust the IP68 rating Apple claims for the Duo.

Juli Clover:

Apple says that you need the Apple Pencil with USB-C for the iPhone Duo, so if you have the Apple Pencil Pro, you may be out of luck.

John Gruber:

Charging is the least of the problems. Because the Duo doesn’t have the magnetic attachment for Pencil Pro, there’s no way to even pair a Pencil Pro.

[…]

Imagine you own an iPad Pro and a Pencil Pro, and you love using the Pencil. You’ve always wanted to be able to use a Pencil with your iPhone. Now you can, if you buy a Duo. But you also have to buy a different Pencil — and then pack two different Pencils whenever you leave the house with both your iPad and iPhone. That’s ridiculous.

Steve Troughton-Smith:

Also let’s not forget that the USB-C Apple Pencil doesn’t have pressure sensitivity, so the artists are already posting their disappointed reactions. I feel like this backs up that @markgurman report that they were planning on creating a bespoke Apple Pencil for the iPhone Duo that later got cancelled, and the USB-C version is the fallback.

Previously:

Update (2026-09-14): Kirk McElhearn:

Folding smartphones are extremely popular in China: there are about as many foldables sold in China as in the rest of the world. Samsung, Google, Huawei, Motorola, Xiaomi, and other brands sell devices like this. Apple will likely sell a lot of devices in China, but given the reactions I’ve seen, they are poised to have a successful product elsewhere, in spite of the high cost.

[…]

For me, a folding phone would mean that for non-work tasks, I would have a larger display, not quite as big as my 11″ iPad Pro. I doubt I would do much work on it, but if I need to check my online accounting app or make a quick edit to an article on my blog, that larger display would be much more practical than my iPhone.

In addition, my eyesight isn’t great. Since the iPhone 8 was released with a larger screen size, I have always bought larger iPhone models. Even with that size, I need to zoom the text on my iPhone a notch above the standard size. A larger display for when I’m reading articles would be a help, not to mention a small, portable device that makes it easier to read PDFs.

Adam Engst:

I may not be the target audience, but I’m sure there are people who aren’t price-sensitive, spend a lot of time watching videos or playing games, and only ever carry their phones in a pocket or bag. But I don’t regularly encounter such people—I hear complaints about phones being too big, but never that they’re not big enough.

David Sparks:

I’ve made my choice. I’m buying the iPhone Duo instead of the iPhone 18 Pro Max.

Steve Troughton-Smith:

I do wonder whether iPhone Duo’s splitscreen multitasking mode will come back to iPad. People have been complaining all year that it went away, but it feels like Duo’s implementation is a simplified, easier-to-understand model. It might make sense to bring back in the future, especially for smaller iPads.

I really like the iPhone Duo. I like the hardware, the form factor, the construction, and how Apple has adapted iOS to work on this specific iPhone.

[…]

But, believe it or not, what makes the iPhone Duo unappealing to me is not the price. It’s not my diminished trust towards Apple as a company. It’s not even the fact that I’m slowly but surely abandoning the Apple ecosystem and don’t want another device that’ll pull me back in.

John Gruber:

The defining aspect of the Duo isn’t that it folds open and closed — we’ve seen almost a decade of Android phones that do that — but its aspect ratio, roughly 1.4 : 1. Because that’s effectively the square root of 2, doubling the outer display’s shorter dimension when you unfold it produces an inner display with roughly the same aspect ratio. That’s elegant and satisfying conceptually. And I think in practice it will feel right, too.

[…]

This aspect ratio is so different that it demands a different UI layout for the Duo to have any chance at being a good experience. That’s exactly what Apple has done, and what Steve Lemay was there in the keynote to unveil. A lot of UI chrome that previously was at the top or bottom of the display is now on the right — the dock on the home screen, the toolbars in apps, etc. And these elements are always on the right. You can’t turn the Duo upside down to move them to the left, nor is there an accessibility setting to move them to the left. This layout puts these controls on the right not because 90 percent of people are right-handed and Apple thinks lefties can get bent, but, I think (and so I’ve been told in conversations with Cupertinoites), because that’s the nature of a book-like shape.

[…]

I’ve only spent a few minutes, in total, playing with the Duo, so I really can’t say whether it succeeds or not. But I will say that it’s weird. Not saying it’s weird good or weird bad — just weird different. In some ways iOS on the Duo feels more different from iOS on all other post-iPhone-X phones than iOS on the original iPad felt from iOS on the iPhones of that time. The original iPad just felt like a much bigger iPhone. The Duo feels like a different layout entirely, in every single app that I had time to poke around with.

[…]

If you only have one display you don’t want it to be the size and shape of the Duo’s outer display. So the questions are: How tolerable has Apple’s UI redesign made it? And how will Duo users split their time between using it closed vs. using it open?

Update (2026-09-18): Hartley Charlton:

Apple’s design team reveals how notebooks helped inspire the iPhone Duo, along with interface principles and expectations for future features, in a new interview with GQ.

Update (2026-09-23): Imthaz Ahamed:

Apple is rightly celebrated for its accessibility work. So I’m left thinking the Duo’s locked layout is a v1 limitation, and that a future software update will offer orientation flexibility. But right now, Apple’s most ambitious new iPhone in years has shipped without it. A book-shaped iPhone should be able to accommodate the people holding it on either side.

Juli Clover:

Apple hardware engineering VP Tom Marieb spoke with TechRadar and shared some candid thoughts about Apple’s upcoming iPhone Duo.

[…]

When asked if the iPhone Duo ‘s crease would be more visible over time, as that’s what tends to happen on other foldables, Marieb said the nano-texture display would help. He asked people to hold the company “accountable” on crease visibility.

Nick Heer:

Perhaps Apple would justify its USB 3.1 selectivity in reverse. The 10 Gbps transfer speeds capable with its recent Pro models are necessary for recording ProRes video to an external hard disk, after all, and professional video codecs are only available on the Pro model iPhones; ergo, those are the only iPhones that need a fast USB controller. But that is no longer an accurate reason, either, because there is now an iPhone which can do 10 Gbps USB transfers but has none of the professional camera technologies. It is the iPhone Duo. And that gives me hope that the rest of the iPhone line will catch up.

Michael Burkhardt:

That said, the company had initially planned to build a new Apple Pencil for the Duo. It would’ve been smaller and attached to the hinge side of the iPhone Duo.

According to Bloomberg, that pencil ran into “technical problems” prior to mass production, so the company scrapped it and went with the traditional USB-C Apple Pencil.

AirPods 5

Apple (video, MacRumors, Hacker News):

Apple today announced AirPods 5, delivering the industry’s best Active Noise Cancellation (ANC) in an open-ear design and even better sound quality, at an outstanding value. AirPods 5 feature an all-new multiport acoustic architecture and next-generation Adaptive EQ for even more immersive sound. Their breakthrough open-ear ANC removes up to 50 percent more external noise compared to AirPods 4 with Active Noise Cancellation, alongside a more natural Transparency mode. Combined with Siri AI and iPhone, AirPods enable users to draw on their personal context and get answers with broad world knowledge, entirely hands-free. Users can also respond to Siri using head gestures, or use Live Translation to help connect across languages.

[…]

For users who want even more, AirPods 5 with Wireless Charging Case deliver great improvements to the AirPods experience. Force sensor with volume swipe arrives on AirPods 5, a first for the open-ear form factor, adding the ability to quickly adjust volume by swiping up or down on the stem.

Battery life is also improved, with up to five hours of playback with ANC on a single charge — one hour longer than AirPods 4 with ANC, thanks to a redesigned battery.

ANC is now available in the base model with the same $129 price, and the higher model is now $149 instead of $179.

Joe Rossignol:

Apple unveiled the first AirPods on September 7, 2016, meaning the iconic wireless headphones are now 10 years old. However, the AirPods did not launch until December that year.

Previously:

Update (2026-09-10): Ivan Pavlov:

AirPods 5 case not getting UWB for “Find My” precise location is a huge 👎️

Update (2026-09-17): John Gruber:

Just like with AirPods 4, Apple continues to make two different products under the same name.

[…]

I found the new AirPods 5 with full noise cancellation to be roughly equivalent to the AirPods Pro 3 in Adaptive mode. That’s pretty good, and makes the ambient noise level in an airplane much more pleasant. But the full noise cancellation mode of the AirPods Pro 3 delivers an entire step change in noise reduction that the open-ear AirPods 5 cannot match.

John Gruber:

The AirPods 5 case doesn’t have MagSafe magnets (the case is seemingly too small), only magnets for the Apple Watch puck. AirPods Pro cases have magnets to attach to both pucks.

iPhone 18 Pro and iPhone 18 Pro Max

Apple (video, MacRumors, Hacker News, Slashdot):

Apple today announced iPhone 18 Pro and iPhone 18 Pro Max, delivering the most advanced pro camera system in an iPhone, and huge leaps in battery life and performance. The new 48MP Fusion Main camera, now with variable aperture, brings creative control that wasn’t possible before, and new Pro controls let users customize their experience in the Camera app. Both models feature a smaller and even more useful Dynamic Island, as well as A20 Pro and a next-generation vapor chamber that together deliver the highest sustained performance in iPhone history.

[…]

Pro controls is a new customizable experience in the Camera app for iPhone 18 Pro and iPhone 18 Pro Max that makes it easier than ever for users to access their most used settings and introduces new options for manual control.

[…]

When a photo is taken in the new Reference mode, the camera captures signed sensor data that Private Cloud Compute develops into an unalterable reference image.

[…]

The upgraded Dynamic Island can now show three Live Activities at once[…]

[…]

eSIM-only models deliver up to 36 hours of video playback on iPhone 18 Pro and up to 45 hours of video playback on iPhone 18 Pro Max.

[…]

iPhone 18 Pro and iPhone 18 Pro Max will be available in 256GB, 512GB, 1TB, and 2TB storage capacities. Available in burgundy, glacier, silver, and black, iPhone 18 Pro starts at $1,199 or $49.95 per month, and iPhone 18 Pro Max starts at $1,299 or $54.12 per month for 24 months.

What I’m most happy to see is the ability to increase the depth of field. I don’t understand what Apple Reference Image is doing that it needs to be uploaded/offloaded to Private Cloud Compute.

Previously:

Update (2026-09-11): Hartley Charlton:

Pro Controls is built around the variable aperture on the new Main camera. Six laser-cut blades move smoothly between four aperture settings, and the Camera app can adjust aperture automatically based on depth of field and lighting, or users can take manual control themselves for what Apple calls “truly unique shots that weren’t possible before” on an iPhone.

Pro Controls works across both photo and video capture. It also introduces Smart Focus Tracking, which uses on-device AI models to lock onto a subject and maintain focus even if that subject briefly leaves the frame and comes back into view.

Update (2026-09-17): Joe Rossignol:

Apple now says the iPhone 18 Pro has a C2 modem worldwide, while the iPhone 18 Pro Max uses the chip in every country except for the U.S.

John Gruber:

To the layman’s eye, though, the 18 Pro just looks like it comes in new colors. That’s not a complaint, just a fact. Oh, but the Face ID infrared camera is now underneath pixels on the display, so the Dynamic Island cutout is now smaller. So the part of the Dynamic Island that is always black is smaller, but because there are now more display pixels next to it, the 18 Pro Dynamic Island can now show three active Live Activities, up from two. Apple is getting closer and closer each year to achieving a no-notch / no-cutout display.

Joe Rossignol:

The first iPhone 18 Pro and iPhone 18 Pro Max reviews have been published today by selected tech websites and YouTube channels, ahead of the devices beginning to arrive to customers and launching in stores this Friday, September 18.

Previously:

Update (2026-09-18): Austin Mann:

I'm here at the beautiful Dunton River Camp in southwest Colorado, where I've spent the last week testing the new camera and features on the iPhone 18 Pro.

John Gruber:

I’m not saying iPhone camera hardware won’t continue to improve after that — I’m sure it will — but I suspect variable aperture is the last remaining “easy win”. I think every camera gain after this will be more incremental.

[…]

I suspect that for sustained use cases, it would be more performant to have the 18 Pro’s new thermal system running the 17 Pro’s A19 Pro chip than to have the new A20 Pro chip running with the 17 Pro’s first-generation vapor chamber. But with the iPhone 18 Pro, you get both: you get the faster and more efficient A20 Pro chip and the second-generation vapor chamber thermal system.

[…]

The 18 Pro is the third generation with the Camera Control button. But that button hasn’t changed at all since the 16 Pro, the phone on which it debuted. At some point in the last year, I gave up on using the Camera Control button as anything other than a simple button. I went into Settings and turned off all the features where you can soft-press it and slide your finger back and forth to adjust camera features while using Apple’s Camera app. What I found is that I kept changing things inadvertently and undesirably. It’s too prone to accidental half-presses that put it into slide-to-adjust for some setting, and because it’s an accident, my finger would start changing things. I turned that all off and I’m much happier for it.

[…]

There’s a minor tradeoff with this design. Even my middle-aged eyes can see that the pixels on top of the Face ID sensor aren’t quite as sharp as those on the rest of the screen. The time of day in the status bar looks like it’s just a tad fuzzy, like the text isn’t anti-aliased correctly.

Update (2026-09-23): DXOMARK (Hacker News):

The Apple iPhone 18 Pro camera performance is evaluated across photo, zoom, and video use cases using DXOMARK’s objective measurements and perceptual analyses to assess imaging performance across common shooting conditions. This article provides a structured summary of DXOMARK’s lab measurements and perceptual analyses to describe the device’s imaging performance.

Tim Hardwick:

Apple’s new Texture and Grain controls for Photographic Styles are not available on iPhones other than the latest iPhone 18 Pro models and upcoming iPhone Duo, despite the company’s original wording suggesting otherwise.

TestFlight Sort Order

Zac Hall (July):

Apple just updated TestFlight for iPhone, iPad, Mac, and more. The new version, 4.3, introduces “a search field to quickly find apps.”

John Gruber:

But when Apple implemented this change, they also changed the sort order of the list of apps you’re registered to test. Starting with this update, the list is sorted in alphabetical order. For as long as I can remember — perhaps dating back to when TestFlight was a third-party utility — the list was ordered by recency. The most recently updated app was at the top; the oldest at the bottom. Sorting by recency is really the only sort order that makes sense when you’re registered for dozens (or more) of apps. For me, trying to see if there is an update to a new app whose name starts with U now requires scrolling through over 100 items.

[…]

Also, if I consider the broader view, this really speaks to how much we’ve lost in terms of UI vocabulary. For decades, any list of items with names and dates could be sorted by name or date, ascending or descending, through the standard use of clickable headers at the top of every list. This was true for almost any such list in any app, on any platform — Mac, Windows, Unix, Amiga, whatever. This was just basic GUI stuff.

[…]

iOS in 2007 introduced a simplified UI vocabulary that omitted many of these baseline GUI features. That seemed like a reasonable trade-off for a device with a 3.5-inch display and fat fingers as the only input device. But then iOS became popular and Apple stopped bringing the richer UI vocabulary of the Mac to iOS[…]

And it starting bringing iOS limitations to the Mac.

It certainly shouldn’t have taken until July 2026 to be able to search in TestFlight, either. And being able to search, and see the results sorted alphabetically, shouldn’t mean you can no longer view the full list sorted by recency.

John Gruber:

Whatever is going on with this sort order, it isn’t affecting everyone. John Siracusa, amongst many others, has the same problem I do — his list is now alphabetical, and it’s driving him nuts too. Ryan Booker, amongst many others, still has his list sorted by recency.

John Gruber (September):

For both of us, yesterday’s v4.3.1 update fixes the bug.

But there should still be more sort options.

Previously:

Update (2026-09-16): John Voorhees:

Returning to reverse chronological order may seem like a small thing, but it’s made a world of difference in keeping up with the apps I test.

Search was near the top of my list of TestFlight wishes for years, and its addition made a meaningful difference to the app’s usability. But I’ve had a lot of TestFlight wishes over the years that are scattered across multiple articles, so I thought I’d share what else I’d like Apple to tackle with TestFlight[…]

Asahi Linux Supports M3 Macs

James Calligeros (Hacker News, Phoronix):

Asahi Linux now officially supports Macs with an M3 series SoC!

Linux support for M3 series SoCs and the machines powered by them is now in a state where almost everything supported on the M1 and M2 series machines just works. This includes the webcam, internal microphones, USB (up to the hardware limit of USB 3 10 Gb/s), hardware accelerated video decoding including support for AV1, WiFi, Bluetooth, and much more! The only major exceptions remain full DCP support and the GPU, which we will have more news on in the coming months.

[…]

Sleep currently does not work due to limitations with the firmware-provided framebuffer. This will be addressed once full DCP support is wired up for M3.

[…]

Although MacBooks and iMacs are supported (M3, M3 Pro and M3 Max), the Mac Studio (M3 Ultra) is not yet supported.

NSToolbar in Golden Gate

John Brayton:

NSTrackingSeparatorToolbarItem adds a white band over the top of the leading split view panes when in full screen mode on macOS 27 [beta 3]. That white band appears to have the height of the toolbar.

He says this was fixed in Beta 4.

John Brayton:

macOS 27 developer beta 5 (26A5406e) introduces a bug that causes a white bar to appear over window content if the window’s toolbar has an NSTrackingSeparatorToolbarItem. I filed FB24266969 with Apple describing this.

Steve Troughton-Smith:

NSSearchToolbarItem has been screwed last minute in Catalyst with less than a month to go? Cool, cool…

That’s the kind of thing that can halt my release plans entirely 🫠

Ron Elemans:

Also screwed up in AppKit, with the macOS 27 beta 5 release.

Also, the titlebarSeparatorStyle setting seems to be ignored. Toolbars in beta 5 always have a separator line and a blurred slightly lighter background.

Weirdly enough Apple’s own apps don’t have these issues.

John Brayton:

In macOS 27 developer beta 5, search fields in toolbars (NSSearchToolbarItem instances) have their placeholder text, search strings, and magnifying glass icons vertically off-center. I reported this as FB24286690.

Mario Guzmán:

Beta 6 also fixes the UI issues with NSSearchToolbarItem. Elements are now re-aligned again, the recents menu is in a good position, and the focus ring is perfectly outlining the entire bounds. :D

SwiftUI Toolbars

Natalia Panferova:

I thought it would be useful to have a single reference for the different ways we can style the toolbar in SwiftUI on macOS 26.

Phil Zakharchenko:

The toolbar id creates a stable customization domain, and each item id gives the framework something stable to persist when the user adds, removes, or reorders controls. This identifiability of toolbar items is a requirement for customization. Under the hood, when SwiftUI inevitably bridges your toolbar contents to NSToolbar, these identifiers will be directly translated to the NSToolbarItem’s itemIdentifiers.

As we continue the migration to a customizable toolbar, we are likely to encounter a few surprises related to this model.

[…]

After a closer inspection, and perhaps a few minutes of digging through the documentation, we come to the bleak realization: there is no customizable ToolbarItemGroup API.

[…]

The regular toolbar model and the customizable toolbar model overlap, but they are not interchangeable. You cannot give a ToolbarItemGroup an id, and you cannot place one directly inside toolbar(id:content:).

Majid Jabrayilov:

Let’s take a look at another example. This one is a bit tricky, because on macOS, you will get Action 1 in the top trailing position and the whole group of actions centered in the navigation bar. On iOS, you will get Action 1 pinned to trailing and all other items collapsed.

[…]

The final addition to the Toolbar API is the toolbarMinimizeBehavior view modifier allowing us to minimize toolbars while scrolling up or down. You can minimize tab, bottom, window and navigation bars with it.

With new modifiers SwiftUI gives us a much better balance between system-driven adaptation and explicit control. We can now decide which actions are more important, which items should always stay visible, which groups should intentionally live in the overflow menu, and how toolbars should react to scrolling.

Natalia Panferova:

iOS 27 includes a few smaller additions that make toolbar content easier to configure.

We can remove the default padding around an item whose content should extend to its edges with contentMarginsRemoved(_:)[…]

[…]

The status bar is now represented by ToolbarPlacement.statusBar, so its visibility can be controlled through the same toolbar API as other bars[…]

[…]

ForEach now conforms to ToolbarContent, which means we can generate toolbar items directly from a collection[…]

Natascha Fadeeva:

Together, the toolbar APIs let us express the importance of each action while SwiftUI continues to handle the toolbar’s layout across different sizes.

McKinley 1.0

Amy Worrall (Mastodon):

McKinley is an all-in-one studio for drawing and annotating SF Symbols. It bundles vector tools with knowledge of the SF Symbols structure, so you can edit one set of objects across multiple weights, sizes and colours. Import SVG or start from scratch, live preview your work using Apple’s own renderer, and export directly to Xcode, so you never need touch the SF Symbols app again!

[…]

Gone are the days of converting your strokes and shapes to outlined paths before export. Keep everything how you drew it, and let McKinley handle the output.

[…]

Link your project’s asset catalog to your McKinley document. Then when you make a change, hit the Sync keyboard shortcut and it’s immediately populated with your latest version.

[…]

McKinley is a Mac-assed Mac app: a native AppKit UI, Quick Look previews and thumbnails for your documents, a full AppleScript dictionary for batch work, and the whole user guide offline in Help.

$60, no subscription. It’s been a while since I had to deal with custom SF Symbols, but I remember it being a major pain. I haven’t had the chance to try McKinley with a real project yet, but it looks very well done. I love seeing a new app ship with documentation and extensive AppleScript support, including sample scripts that you can install right from its script menu.

Mario Guzmán:

The icon isn’t just a symbol but a whole artistic creation on a canvas.

Look at how your tools are on panels that could be individually opened on their own auxiliary window. I can’t stand the single-window, everything buried into a single-sidebar design we get these days.

Amy Worrall:

SF Symbols rendering does a surprising amount behind your back: it interpolates nine weights from three masters, applies optical size adjustments, resolves hierarchical opacity ladders, and changes some of this between OS releases. Any preview I rendered myself might diverge from the real thing in ways nobody would notice until the symbol was in an app looking subtly wrong. (Obviously I aim to get my canvas rendering with the exact same nuance as Apple’s renderer, but programmers are fallible and the fewer ways things can diverge, the better.)

Apple provides no API for “here’s my SVG, render it as a symbol”. For a normal app using a custom SF Symbol, the symbol is compiled from an Asset Catalog in Xcode into a .car file (a compiled asset catalog) at build time. But there’s no ‘build time’ when I want to update a preview in McKinley.

My workaround involves compiling your symbol into a .car file at runtime, on every edit, by patching bytes into a template, then loading that temporary .car file into McKinley via NSBundle.

Previously:

Update (2026-09-08): John Gruber:

I mean just look at McKinley. It’s both beautiful and quite obviously a serious professional tool.

Update (2026-09-11): Amy Worrall:

Anyone used any great implementations of dockable palettes? (Adobe’s don’t count, I don’t think they’re great!)

I’m not going to go back to sidebars, but some kind of options/flexibility might work, if it doesn’t get in the way!

Ternus and the App Store

Mark Gurman (tweet, John Gruber, Mastodon, 9To5Mac):

The Schiller exit is a bit more notable. Unlike Maestri, he still had a real job: The veteran executive ran the App Store and Apple Events. The App Store portion alone is no joke. It generates an estimated $30 billion a year and can be very challenging to manage. Apple’s app marketplace is loved by many consumers, but often criticized by developers and subjected to increasingly onerous regulations. It was a busy, all-encompassing gig and nowhere near a semiretirement.

[…]

But there’s a bit more to the story, I’m told. Ternus and services chief Eddy Cue want to make even more money from the App Store and figure out ways to raise margins and squeeze additional recurring revenue from the platform. Schiller, on the other hand, seems to believe that such moves will only further irk developers and governments. While there was no internal blowup or anything like that, it’s something he wanted no part of.

“Product guy” dreams about margins, forgets that people buy Apple hardware because of the software.

Tim Hardwick:

Apple admitted during its July earnings call that regulatory changes have started to weigh on its Services growth. Apple reported services revenue of $30.7 billion for the June quarter, a record for the period but short of the $31.4 billion that analysts expected.

Patrick Smith:

The hardware guys treating third-party developers like they do their suppliers has stifled Apple’s software platforms

M.G. Siegler:

I thought that perhaps with the move to John Ternus as CEO, it could also be an obvious time to revisit such policies. But I hadn’t considered that Apple could actually be in favor of making them more onerous.

Banktivity Document Model and Rewrite

Ian Gillespie (2025):

Banktivity has traditionally been what’s known as a document-based app. It lets you create and open independent files (or documents), each with its own data. In contrast, many modern apps—Music, Calendar, Photos—are library-based. These apps typically have a single window and a unified data set.

We’ve long appreciated the flexibility our document model provides. But in practice, most of our customers use only a single file. And more critically, this architecture makes it much harder to integrate Banktivity with the broader Apple ecosystem.

[…]

The shift from a document-based model to the new Organizer framework marks a major step forward for Banktivity. It simplifies how users interact with their data while laying the foundation for deeper system integration, background syncing, and a more seamless multi-device experience.

This follows MoneyWell also getting rid of the document model. From my perspective, it’s a shame. I prefer the flexibility of being able to have different accounts in different documents, choosing where to store the documents, and even splitting the same account across multiple documents for performance reasons.

Ian Gillespie (2025):

Ledgers contain an entire, independent set of accounts, categories, investments, goals, budget and so on. Many customers will only have one Ledger for the finances they manage. But we also know there is a good number of customers out there that manage finances across family members, non-profits and small businesses – for these customers, support for multiple Ledgers is crucial.

[…]

While UI is what you see, most of the hard work has been in the architecture. The Library framework — the backbone that replaces our old document system — is in place. That means we can now reliably connect your Banktivity User Account with all of your Ledgers, whether local or synced to the cloud.

Ian Gillespie:

Refactoring Banktivity from a document-based app into a library-style app was a significant undertaking. It changed some very fundamental assumptions in the code. Ledgers can now be opened and closed in the background, multiple windows and scenes can be active at once, and the Organizer has to coordinate local files, cloud sync, user accounts and application state in ways the old document architecture never had to.

Banktivity 10.0 laid the foundation for that transition. With Banktivity 10.1, a major focus has been strengthening that foundation. We’ve spent a lot of time simplifying the underlying architecture, eliminating race conditions and threading issues, and improving how ledgers are opened, closed and managed.

.name Termination

Neil Fraser (via Hacker News):

Nearly twenty-five years ago I registered neil.fraser.name to provide a stable presence on the Internet. It has been the home of this website, my email address, and a server for APIs.

[…]

On 15 April 2026 Verisign proposed the destruction of the entire 3rd level of the ‘.name’ hierarchy in order to simplify their administration. Astonishingly, on 28 July 2026 ICANN approved this action.

[…]

One of my original reasons for choosing ‘.name’ was that it was run by Global Name Registry -- more specifically, it was not run by Verisign. I had history with Verisign and did not trust them. Unfortunately, Verisign acquired Global Name Registry a few years later.

He’s going to lose his site and e-mail address, and someone else could potentially register the domain and hijack his accounts.

SoundSource Support Follow-Up

Chris Barajas:

To spread the word, we announced SoundSource 6 on our blog and sent a mass mailing to our customer list. We also took a more targeted approach, contacting both existing and potential customers who’d previously reached out to us with specific requests. We went back to those folks to let them know about the changes that would interest them most.

[…]

A real live person writes every email response our support team sends, and that human touch takes time. The process is helped along by text snippets, replies that we write once and then reuse and adapt to answer common questions.

[…]

To decide if an email should be sent to a customer, we checked Help Scout’s conversation history, as well as our own custom app for their order history. For example, if someone requested several features across different emails, we’d pick the one that was most impactful, then delete other drafts to avoid inundating them with multiple messages.

UK App Tracking Transparency Lawsuit

Reuters:

Apple is facing a £2 billion ($2.7 billion) London lawsuit brought on behalf of app developers over its app ​tracking rules, with the iPhone maker accused of abusing its power to unfairly impose greater restrictions on third parties.

[…]

Lawyers bringing the new lawsuit ​against Apple, though, say the feature imposed stricter requirements on third-party app developers ​than on Apple’s own services, giving its advertising ecosystem a competitive advantage.

Via Ben Lovejoy:

The latest lawsuit has an interesting twist: it’s being brought by Ann Pope, who was previously a senior official with the regulator behind today’s case.

Kris Holt (Slashdot):

The company told Reuters it was “bound by the exact same requirements as all developers.”

However, regulators across Europe including in France, Italy and Poland have investigated ATT. Germany’s competition regulator, the Federal Cartel Office, last month determined that Apple was favoring its own apps over those from external developers.

Amy Worrall:

The EU is saying “you’re big enough that you have to treat your other business models like third parties” and Apple replies with “but we know we’re solid, so that makes no sense!”

App Tracking Transparency Changes in Germany

Joe Rossignol (Hacker News):

Apple has agreed to make changes to its App Tracking Transparency feature in Germany, according to the country’s competition regulator.

[…]

In Germany, Apple has agreed to remove “possibly discouraging symbols and wording” from the App Tracking Transparency prompt, the regulator said. Apps will also be “given more scope to explain to users what significance personalized advertising has for their offering and their business model,” and the “freedom to combine the consent request required by Apple with the consent requests required under data protection law.”

Ben Lovejoy:

The FCO’s objection appears to be that Apple’s existing prompt is making app tracking sound scarier than it really is. The iPhone maker will make eight changes in order to address this – including removal of the word “track.”

Nick Heer:

The regulator helpfully offers an illustration of the differences between these prompts on the fourth page of its FAQs (PDF) about the case. There are many things they say could be deterrents in the App Tracking Transparency dialog, and I do not think Apple would deny that they are suggesting that users opt out of tracking. The definition of “tracking” Apple uses is self-serving, which would not matter so much if it did not also have a parallel desire to grow its advertising business.

[…]

A particularly damning finding in that comparison, to my eyes, is the way Apple puts “Ask App Not to Track” as the topmost button in the App Tracking Transparency dialog, but puts the option to “Turn Off Personalised Ads” at the bottom of it its own advertising prompt.

Previously:

Update (2026-09-18): Nick Heer:

Apple did not even bother to link to the specific section in its documentation. It is a shame because these changes are, for the most part, very good. There is a new prompt screen that addresses a complaint I have with App Tracking Transparency. Instead of being a small dialog box with almost no information, it is now a whole-screen sheet that describes the mechanism of tracking, and permits developers an option to link out to a page with a developer-provided explanation.

Developers are also now allowed to ask again for permission on an annual basis. Apple says this is “regardless of whether that choice was to accept or reject”, but I doubt many developers who got a green light the first time will ask again. This could be irritating, but Apple itself provides precedent for reminding users of their privacy preferences: iOS occasionally — perhaps every few months — reminds me that an app has access to my location or my photo library and asks me to confirm my choice.

And, of course, iOS and macOS themselves repeatedly prompt you to share information with Apple.

Preparing to Update to Golden Gate

Howard Oakley:

As those new models start shipping on 22 September, the window for the first public release of Golden Gate has narrowed to 15-22 September, with greatest likelihood on the same day as the arrival of those new Macs.

[…]

At the same time as the release of Golden Gate, we should get Tahoe 26.7 and Sequoia 15.8, but it looks increasingly likely that the final version of Sonoma has been 14.8.9, released on 6 August.

Howard Oakley:

As we prepare to flee from the visual horrors of macOS Tahoe at last, this article is a reminder that it wasn’t the first major release of macOS that has had blatant bugs in its interface, although I suspect it may be unique in that those were intentional. While progress in Golden Gate has been limited, I hope you’ll find it rectifies some of the worst errors of Liquid Glass.

Many Macs will be left behind, as Golden Gate drops support for Intel.

Normally, I update around January. With Tahoe I waited until July. This time, I’m considering updating to Golden Gate soon after its release. The downside is that Xcode 26 doesn’t run on Golden Gate, so I would have to drop support for many older macOS versions (about 3% of my customers’ Macs). But it seems like Apple’s going to force that soon, anyway, as one of the next Xcode 27 updates will likely drop support for Tahoe. I want to get off Xcode 26, both to use the newer SDK and because there are various debugging/testing things that don’t work properly.

Mario Guzmán:

I am working on a new app. Right now, I am targeting back to macOS Sequoia. I think that would be a good OS to target but becoming quite old with Golden Gate just around the corner. […] I wonder if I should just target macOS Golden Gate and focus testing on that.

Update (2026-09-04): Isaiah Carew:

i’m in the exact same boat. i’d really like to stay on macOS 15 and whatever Xcode works there. it means i can still build things in the old UI and mostly Tahoe and GG respect it.

but recent bug reports from beta testers and the inability to see these bugs on my VM has made me feel very stuck here — like apple has purposefully made it difficult to move forward and support older versions too.

Update (2026-09-11): Howard Oakley:

What if any preparations do you need to make before upgrading or updating then, or in the coming weeks?

Update (2026-09-16): Adam C. Engst:

So who should upgrade immediately, and who should wait? Let’s consider a few broad categories of users.

Google Ads Remedies

Ryan Whitwam:

A US federal judge has sided with Google, ruling that the company will not have to sell its online advertising exchange (previously known as AdX). The US Department of Justice (DOJ) sought this remedy in the long-running ad tech antitrust trial, which Google lost in 2025. However, the remedies imposed upon Google for that loss are shaping up to be minimal.

[…]

While divesting the ad exchange would have been the most serious penalty, the government also asked for fines and court-ordered changes to Google’s business practices. It’s likely that the DOJ will get a lot of that, but we don’t know the specifics yet. Judge Leonie Brinkema has sealed the order for 14 days, giving the parties a chance to request redactions.

[…]

After all these years of hearings, appeals, and decisions, Google’s market power will remain largely unchanged going forward.

Google and Epic Cancel Settlement, Third-Party App Stores

Ryan Whitwam (Slashdot):

The settlement between Google and Epic that aimed to put to rest the companies’ long-running antitrust battle is being withdrawn, and that means third-party app stores are coming to the Play Store.

[…]

While Apple suffered little penalty in its Epic case, Google was tripped up by its anti-competitive management of the supposedly open Android ecosystem. Google used its market position to discourage device makers from promoting or pre-loading non-Google app stores and attempted to hide that conduct. The remedies set by Judge James Donato included lower fees, mirroring Google Play apps in other stores, and most vitally, placement of alternative app stores in Google Play.

[…]

Google and Epic were set to return to court on July 16 to argue in favor of the settlement. However, the writing may have been on the wall. In a recent expert analysis provided to the court, MIT economics professor Nancy Rose noted that the settlement was “unlikely to enable Google Play’s potential competitors to overcome their long-standing network-effect disadvantage in a timely manner.”

[…]

Under the terms of Judge Donato’s original injunction, these stores will have access to the full catalog of Google Play apps by default. […] Google will also require approved stores to block malware, respect intellectual property, and include mechanisms to update and uninstall apps.

John Gruber:

My guess is that all the big app developers will opt out of this. Games, though, maybe not?

Apple’s New Evidence in OpenAI Lawsuit

Juli Clover (Hacker News):

Liu downloaded the circuit schematic from Apple in March, two months after he left the company. Liu used the schematic to run a simulation using electrical engineering tool LTspice, and then messaged people telling them he ran the simulation for power conversion development work.

[…]

Liu used the Apple schematic on a Mac mini that later synced to the MacBook he took from Apple, which is why Apple knows about it. Apple now wants to investigate the Mac mini and other devices Liu still has in his possession.

Apple says the “shocking evidence” is proof that its trade secrets are in active use and evidence is being destroyed, which is why expedited discovery is needed.

John Gruber:

The first point seems really bad for OpenAI. On the fourth point, I’m not sure what Apple is alleging here — I think they’re alleging that Liu took an Apple internal engineering app with him over to OpenAI?

William Gallagher and Mike Wuerthele (MacRumors):

OpenAI has responded to Apple’s latest filing about the theft of confidential information, by filing its own rebuttal which again accuses the company of trying to stop employees leaving. According to Reuters, OpenAI is now also calling out Apple for being behind on AI.

[…]

“[Employees] can leave a company like Apple that has struggled to adopt AI and move to an exciting startup that builds innovative products,” says OpenAI in its new filing. “Apple may not like those choices. But it cannot claim those choices are unlawful, and it cannot use its own sloppy procedures to blame others for its own mess.”

Ben Lovejoy:

On the face of it, the evidence Apple provided yesterday does appear damning. OpenAI doesn’t seem to be denying that confidential Apple information was used by the company, but rather claiming that the iPhone maker failed to properly protect it.

It sounds like there’s a lot of evidence against Chang Liu, but Apple is suing OpenAI.

Pitching Apps in the AI Era

Adam Engst:

So I was quite surprised earlier this year when I started to receive personalized pitches from indie developers, a few at first, and now several per week. Many seem to be building apps with AI assistance, but more to the point, they seem to be getting AI help with promoting the apps as well. They often reference our still-current prohibition on press releases with a nominally personal email, but for someone as steeped in words as I am, it’s obvious that an AI is doing the writing.

[…]

At first, this reliance on AI rubbed me the wrong way. But then I realized that it wasn’t really any different than a software company outsourcing its media relations to a PR firm. Those communications had a certain form and set of expectations, and while these new AI-generated messages have a different form, the expectations (coverage) are pretty much the same. AI is simply the new PR agency. Which undoubtedly dismays PR professionals, but there’s still room for those doing PR right.

The problem I have with these new pitches isn’t that the developers used AI to generate them; it’s that they often don’t do it very well.

I’ve noticed a huge increase this year in people pitching me their apps. Many of them seem to have been coded with the assistance of AI. For some app categories, this worries me, and there also seems to be less care taken in following Mac platform conventions. But it’s also exciting to see such a flurry of development, both totally new ideas and fresh takes on old niches. I have a large backlog that I’d like to write about. (There are also many almost indistinguishable variations in certain categories.)

Separately, as Engst says, many of the pitches (and sometimes even the sites) are obviously written by AI. This rubs me the wrong way. I don’t mind at all receiving a generic press release or even a one-liner with a link. But these lengthy e-mails, customized for me, purport to be personal communications when they really aren’t. Sometimes I’ll reply with questions or feedback, and it feels like the entire conversation is with an AI.

When people put in some effort to pitch me their product or article, I’ve always tried to give them a decent reply. Often, I end up learning something or wanting to follow their other work even if I don’t end up writing about what was pitched. This is unfortunately no longer sustainable. There are too many pitches, and it’s demotivating talking to bots. I have to be much more selective about interactions. I appreciate hearing about all the apps, but I’m focusing on the ones that particularly interest me, and I’m less likely to even click the link if it seems like an AI pitch.

TipKit for the Real World

Craig Hockenberry:

Then, when you look at the sample code, it’s all SwiftUI. At least the sample compiles and runs because it uses a completely different syntax than what was shown at WWDC.

[…]

Eventually I stumbled upon TipUIPopoverViewController which inherits from UIViewController. That should work! […] But it didn’t: the close button on the popover didn’t work.

[…]

Until you realize that any changes you make are stored in a SQLite database, debugging is very confusing. It’s also easy for your own state to get out-of-sync with the Tip state: there is not a single source of truth.

[…]

Unfortunately, that sample code doesn’t scale well. If you have a view with multiple tips, you’re going to be littering your code with tip instances, observation tasks, and popover controllers. It’s a mess and a clear sign that the TipKit developers didn’t think much about UIKit.

Fatbobman:

In the previous article, we introduced the basic usage of TipKit. In this article, we will discuss some advanced topics related to TipKit, such as how to fully customize Tip views (not using TipView and popoverTip), how to use TipKit with UIKit, and how TipKit can share data across different applications, as well as how to reuse Tip declaration code. Additionally, we will attempt to address some common questions and concerns about TipKit.

John Ternus Is CEO

Joe Rossignol:

Apple’s former hardware engineering chief John Ternus officially became CEO of the company today, with the change now reflected on Apple’s leadership page.

[…]

Tim Cook is now executive chairman of Apple’s board of directors, after a 15-year run as CEO.

Apple:

John joined Apple’s product design team in 2001 and became a vice president of Hardware Engineering in 2013. He joined the executive team in 2021 as senior vice president of Hardware Engineering. Throughout his tenure at Apple, John has overseen hardware engineering work on a variety of groundbreaking products and was instrumental in the introduction of multiple new product lines, including iPad and AirPods, as well as many generations of products across iPhone, Mac, and Apple Watch.

John has led much of the company’s focus in areas like reliability and durability, introducing new techniques that have made Apple products remarkably resilient. He has also driven much of Apple’s innovation in materials and hardware design that have reduced the carbon footprint of its products, including the creation of a new recycled aluminum compound that has been introduced across multiple product lines, the use of 3D-printed titanium in Apple Watch Ultra, and advancements in reparability that have increased the life spans of several Apple products.

Prior to Apple, John worked as a mechanical engineer at Virtual Research Systems. He holds a bachelor’s degree in Mechanical Engineering from the University of Pennsylvania.

Myke Hurley (9To5Mac):

This feels like Apple really trying to remind us of a previous product-focused CEO.

[…]

I would not have predicted this [reliability and durability] angle being so prominent, so I can only assume it’s something that’s important to Ternus.

[…]

One of the key tenets of the Cook era was Apple making a series of environmental pledges. I am very happy to see this called out as something Ternus is interested in.

There’s no mention of software.

Juli Clover:

Ternus sent his first memo as CEO to employees this morning, praising Cook and sharing his excitement for Apple’s future.

Benjamin Mayo:

The 5 GB free iCloud tier lasted Tim Cook’s entire career as CEO, how will Ternus stack up?

Previously:

Update (2026-09-02): Juli Clover:

Apple has set new CEO John Ternus’ target compensation at $58 million, according to an updated SEC filing [PDF]. Tim Cook’s target compensation is $47 million in his new role as executive chairman.

Update (2026-09-07): Ryan Christoffel:

But a new profile published today at the Financial Times adds fresh details and insights to the story.

Regarding Ternus’s reputation inside Apple, it says he “is known within the company for being both highly competent and unshowy.”

It doesn’t seem like there was actually much insight, but I’m linking to this for completeness.

Swift 6.4: Warning for Weak Captures Within Nested Closures

John Sundell:

New in Swift 6.4 […] is a warning which is emitted when a nested closure performs a weak capture while the parent closure implicitly captures that object as a strong reference.

At first glance, that new diagnostic could be a bit puzzling, since it might seem unnecessary to have to specify such a weak capture twice (or, alternatively, move it to the parent closure’s capture list), but it turns out that it’s an incredibly useful new warning that can help us avoid a quite common kind of memory management bug.

[…]

Finally, in situations where capturing self strongly doesn’t actually lead to a retain cycle, we can silence the new warning for nested weak captures by explicitly adding self to the outer closure’s capture list, such as when creating a Task within the following example[…]

Ending the Golden Era for Backward-Compatible Apps

Matthias Gansrigler-Hrad:

I don’t appreciate being forced by Xcode 27 to drop support for macOS 10.13-11.0. It’s my decision which OSes I want to support, not Apple’s. Yes, I can keep Xcode 26 around until submissions require Xcode 27, but what then?

Originally, Xcode 27 was documented as supporting Big Sur on Intel Macs, but now the earliest is Monterey.

I’m frustrated, too, but it’s more honest than the recent releases that claimed to support deployment on older macOS versions when Apple clearly hadn’t tested that it actually worked. I filed bugs, and Apple kept responding that they’d fixed it, when they hadn’t.

Using old versions of Xcode isn’t a great solution because they aren’t supported on Golden Gate. Swift also makes it more difficult to call newer APIs when using an older SDK. You can’t just copy/paste a method prototype or constant value and conditionally use it when running on a newer OS.

Ighor July:

I eventually found a hidden workaround that changes the errors back into warnings. That is good news, but it does not make the concern disappear. The setting is undocumented, absent from the normal Xcode interface, and currently being tested only in a beta toolchain. The larger question is what Apple intends to enforce when Xcode 27 is final and, later, when App Store submission requirements move to its SDKs.

[…]

Apple’s current Xcode system requirements list Xcode 26 with deployment targets beginning at iOS 15 and macOS 11. Yet developers have been able to enter older targets manually. In an Apple Developer Forums discussion about Xcode 26, an Apple product manager explained that the published deployment target range is aligned with simulator support and on-device debugging. The accepted answer confirms that an iOS 13 target can still build even though it falls below the range in Apple’s table.

My own tests went further. Xcode 26.5 compiled a project targeting iOS 9.0. It warned that the target was older than the supported range, but the build succeeded. On macOS, I have compiled current apps with deployment targets as old as macOS 10.9. Xcode warned me, but it still produced working applications.

[…]

For iOS and iPadOS, staying on Xcode 26 is not a lasting option. Apple has repeatedly made a current Xcode and SDK mandatory for new App Store submissions. […] If any one of those conditions fails, iOS and iPadOS developers will have no normal App Store path for publishing new updates that still support versions older than 15.

Previously:

Update (2026-09-07): Léo Natan:

Just want to remind you guys that if you move to Xcode 27, the only “officially” supported and sanction Xcode for GG, UIDesignRequiresCompatibility is no longer respected across the 27 OSes (apps built with older Xcodes still are). So you might suddenly find out you have a lot of work ahead of you, adding support for the dreaded Glass. And 27 Glass is not the same as 26 Glass. That can be an issue if you skipped 26 altogether but still want to support it.

Previously:

Update (2026-09-11): Nick Lockwood:

I mostly ignored the Xcode 27 betas (mainly due to the barely-usable Device Hub) so I didn’t realize the passive-aggressive prompts to drop support for iOS < 15 that you get when submitting apps is being backed up by Xcode 27 refusing to compile apps at all unless you bump the deployment target 😧

App Store Moves From Phil Schiller to Eddy Cue

Juli Clover:

As Apple Fellow, Schiller continued to oversee the App Store and Apple events, but the role may not have left him with sufficient time for his own endeavors. In 2024, The Wall Street Journal said Schiller was working close to 80 hours a week.

[…]

Schiller is stepping down from overseeing the App Store and Apple product launches just as John Ternus is set to take over as Apple CEO.

[…]

Apple is moving the App Store to Eddy Cue, who oversaw it until 2015. Cue is Apple’s services chief and will reportedly be taking a more influential role under Ternus’ leadership. Carson Oliver, who has long been on the App Store team, will oversee its day-to-day operations.

Mr. Macintosh:

Phil Schiller was right there with Steve Jobs and Tim Cook at the start of Apple’s comeback in 1997-1998.

He is officially stepping back to only his Apple Fellow role.

Phil has a combined 35 years of service to Apple 1987 - 1993 & 1997 - today

SuperDuper’s “Follow-Up”

Dave Nanian:

Recent versions of xOS (that is, macOS, iOS, iPadOS, etc) have Data Protection Classes from A to D that get assigned to files and folders.

[…]

The thing is, though, is that these files and folders are inaccessible unless the user is logged in, and the screen is unlocked. A few seconds after the screen locks (or you log out), the keys are purged, and they cannot be read.

[…]

That means the files any application considers to be worth protection cannot be accessed when a backup usually happens.

[…]

You may have noticed that if you had an overnight backup, when you unlock your screen, a copy starts to run. It’s typically quite brief, thanks to ⚡️Turbo Smart Update, but it might surprise you anyway. […] During your overnight copy, SuperDuper kept track of the files that it couldn’t access due to their protection class. And now that it can access them, it’s making sure they get backed up.

This seems like the right thing to do. Time Machine also does it. A backup app should try to make as faithful a backup as possible. I kind of find it annoying, though. Sometimes it can’t do a Turbo Smart Update, and so the backup that should already be done may end up taking another 30 minutes or more. The best thing to do is schedule backups while you’re using your Mac to avoid SuperDuper needing to do such “follow-ups.”

I wrote some code to try to figure out which files I have that are using data protection. Interestingly, the URLFileProtection API seems to not work on macOS. I used the lower level getattrlist() instead. Nanian recommends fcntl(). I didn’t find any protected files that I actually care about, just caches and derived data from Apple’s own apps. But, in theory, Apple or a third-party app could be saving actual user data using data protection.

Indie Podcast Apps Not Growing

Dustin Bluck:

Independent podcast apps are not growing as a category. This is not a particular secret, but perhaps you haven’t seen it stated explicitly. It’s the sort of thing that has to be inferred, but there’s plenty of available data if you look for it. While the podcasting sector has seen growth, this has occurred almost entirely on platforms like YouTube, and the independent podcast app userbase has mostly just stood still.

[…]

I’m sure somewhere out there a 21-year-old just downloaded Castro or Pocket Casts for the first time and thinks RSS feeds are awesome (if you are this person, please email me). But every number I can see indicates the userbase is both static and aging. Every new customer I talk to has used some combination of Apple Podcasts, Overcast, Pocket Casts, or Castro for at least the last 5 years if not the last 10.

[…]

Perhaps there are healthy businesses that get very few new users but instead gracefully age with the ones they have. Ferrari maybe? Buddy, smartphone apps are not one of those businesses.

[…]

I would rather work on flashy features to capture new users, but, reality being what it is, I have to think about things in terms of both the health of the ecosystem and what will actually help retain existing podcast app users.

Nick Heer:

Anil Dash wrote, in 2014, that the simple phrase wherever you get your podcasts is a “radical statement”:

[…] Because what it represents is the triumph of exactly the kind of technology that’s supposed to be impossible: open, empowering tech that’s not owned by any one company, that can’t be controlled by any one company, and that allows people to have ownership over their work and their relationship with their audience.

Video podcasting changes that. In its simplest form, it is just a YouTube channel, which means it is siloed and controlled by Google. Spotify also supports video but only in its app.

Ilya Birman:

So Marco described a problem. What if someone manually asks to download an episode when they already have three downloaded? You can’t just immediately delete it to keep things tidy. So what do you do? Marco added a special hidden “episode downloaded manually” flag to the database, so those episodes would not count towards the limit.

This is one more example of how even the most seemingly trivial features require thinking through and accounting for different cases that may not be obvious at first glance. Every user interface designer and product designer should collect and absorb examples like this.

[…]

Finally, Marco’s wife Tiff suggests a solution to all the problems: just don’t let users download more episodes, she said, and show them a message, roughly: “Your episode limit is three, but this would be the fourth, denied”.

Marco liked the solution. I didn’t. Sure, it solves Marco’s problems, but not the user’s.

Marcin Wichary:

Birman presents this as “Let me click,” but I wanted to offer two alternative/​complementary principles that helped me before:

  • Let me do things in any order. Here’s Google Home app, where I can change the temperature and the time for holding – but if I change the time first, it frustratingly resets when I subsequently change the temperature. It forces one specific order in an interface that suggests any order is okay[…]
  • The current action has the most momentum. The user is right there, active, tapping on things, wanting to get stuff done. If Overcast indeed throws a “your episode limit is three” message, then it forces the user to remember how to get to the settings and change it. The momentum is lost. The decisions of past me should not be as important as the decisions of present me.

Marco Arment:

FWIW, the entire strict-limit feature is gone in the pending update (awaiting App Store review). EVERYONE hated it.

Now I’m just displaying the added-manually status in the UI and allowing it to be toggled manually in the “…” menu.

Marco Arment:

I’ve needed to evolve my expectations for what my role in Overcast is.

After building up a large, passionate userbase over a very long time, it’s not really entirely mine anymore. I can’t just do whatever I want with it.

And the growth era of open/RSS/indie/whatever podcast apps is over. The business is now about serving and retaining my existing customers for as long as possible.

So I can add things here and there, very carefully, but I can’t really change anything significant.

Aren’t Snapshots Purgeable?

Howard Oakley:

Since High Sierra and APFS snapshots, accounting for purgeable space has been inconsistent and often misleading. I first reported this over eight years ago in Sierra 10.12.6 and High Sierra 10.13.3, and most recently three years ago in Ventura 13.3.1. This article looks at how this is handled now in Tahoe 26.6.2.

[…]

There is disappointingly little documentation on space management in macOS, and the closest Apple comes to defining purgeable space is in Disk Utility’s Help pages, where it’s stated to be “space that macOS can free up when needed by removing files from your computer (you can’t manually remove the files that are designated purgeable, but macOS removes them as space is required)”.

On the face of it, that includes cache files but not snapshots, as they can be manually removed in Disk Utility, as I’ve discussed in detail here. This is contradicted when using tmutil localsnapshot to make Time Machine snapshots, which reports that “local snapshots are considered purgeable and may be removed at any time by deleted(8)”, as deleted is the purgeable space and cache management service in macOS.

APFS snapshots can also be created by third-party apps that have the appropriate restricted entitlement. Apple doesn’t explain whether those too can be purged by macOS when additional free space is required.

Howard Oakley:

Before macOS will start copying a file to a volume, it checks whether there’s sufficient free space available. I believe this is normally performed by the FileCoordinator API in Foundation, and appears in the log with the subsystem com.apple.foundation.filecoordination.

If there isn’t sufficient free space to accommodate the file to be copied, deleted in the subsystem com.apple.cache_delete checks whether enough space can be freed by purging items known to be purgeable in the destination volume. deleted has a fixed set of services that can be called on to purge items, listed in /System/Library/CacheDelete.

[…]

Space-based purging of Time Machine local snapshots is unreliable. The reason for this is that Time Machine CacheDelete fails to report purgeable space when it’s available. Even when it does work, it can take nearly half an hour for Time Machine CacheDelete to recognise the appearance of purgeable space.

Sometimes you need to do it yourself with Disk Utility.

Previously:

Update (2026-09-03): Howard Oakley:

  • When purgeable space is required, deleted (subsystem com.apple.cache_delete) first discovers purgeable space for each caching service, to determine whether it’s sufficient.
  • If it is, and the decision is taken to purge caches, caching services are called on to free up space by purging their caches as required.
  • Purging may then take place in phases until sufficient space has been freed.
  • Purging is frequent during installation of macOS updates, even when there’s ample free space available.

Update (2026-09-08): Howard Oakley:

In the event that you’re caught out by circumstances, such as the combination of recent large snapshots and exceptionally large caches, macOS does try to manage as well as possible even when there’s just a few GB free. But once free space falls to around 1 GB you should see a warning notification.

[…]

From then on, most file operations, even creating a new folder, will fail. That applies to all apps, regardless of whether they handle those failures gracefully and warn you of the error. Actions like taking a screenshot start normally, but after their image has floated across the display, they just vanish and can’t be saved.

[…]

The worst combination of problems occurs when a Mac runs out of free disk space and physical memory at the same time. macOS memory management then wants to allocate space in the VM volume as its backing store for virtual memory, but in the absence of free space to do so, that fails and should propagate as a memory allocation error.

Update (2026-09-09): See also: Accidental Tech Podcast.

GitHub Outage

Vlad Fedorov (Hacker News):

On August 17, GitHub experienced an outage that lasted 7 hours and 47 minutes. It disrupted github.com, authentication, GitHub Actions, APIs, pull requests, issues, and Copilot, affecting developers and organizations around the world.

[…]

Neither outage was caused by a code or configuration change. Both incidents were capacity failures at their core. We failed to scale critical components before demand exceeded their capacity. Since April, monthly commits have grown from 1.4 billion to 2.9 billion. That growth explains the pressure on our systems, but it does not excuse these outages.

[…]

As part of the reliability commitments we made earlier this year, we have focused on three priorities: adding capacity, improving efficiency, and removing architectural bottlenecks. We have since added more than 3 million CPU cores, 120 petabytes of high-speed storage, and significant network capacity. We installed as much hardware as available power allowed in our existing data centers while accelerating our migration to Azure.

Alejandro Forero Cuervo:

This is the wrong way to think about this because there’s no such thing as infinite capacity. A large distributed system will be simultaneously mostly idle and (in some subcomponents) overloaded. The root cause is not “a component didn’t have enough capacity (because of auto scaling failures)”, but rather “this complex system collapses (rather than degrade gracefully) when demand exceeds capacity”.

When components reach capacity limits, the excess traffic of the lowest priority should be rejected. Rejected traffic should not be retried — in fact, not only should clients not retry these errors, these errors should cause client-side throttling. Traffic isolation should be applied — if the cause of the overload is a single client/customer system, no other system should be affected.

Nearly a decade ago I wrote about some of the techniques we applied at Google to implement these protections. Most other large internet services have since copied them, afaik.

Testing Tip: Make Your Keyboard Fast

Marcin Wichary:

By default, on a Mac, the initial delay is 500ms, and the key repeat rate 1000ms.

[…]

My suggestion is to make them both as short as possible for testing.

[…]

First, it’s good to test whether your keystrokes behave well when repeated. Occasionally you might want your interface to suppress repeating, or do something special if the key is held longer.

Second, it’s a good test not just of repeating, but just the user pressing keys really fast.
