Tahoe Display Flicker

Juli Clover:

Mac users with the Studio Display have been complaining about intermittent flickering since the update launched in September. There are also complaints from users who have other kinds of displays, so it might be a bug that is affecting more than one type of external monitor.

We have experienced this issue with a MacBook Pro running macOS Tahoe connected to a Studio Display, and the macOS Tahoe 26.1 and macOS Tahoe 26.2 updates haven't improved the situation at all. In fact, the flickering seems to be getting worse in recent days.

Dan Moren:

I’m glad this is finally gaining some attention because I have been seeing this since the earliest betas of Tahoe back in June (I complained about it again more recently). And that’s been on multiple Macs, including my Mac mini attached to a Studio Display, my old M1 MacBook Air, and my current M4 MacBook Air.

Oliver Haslam:

It’s thought that this dithering causes a flickering effect which, in some cases, can even cause headaches. Thankfully, a third-party utility called Stillcolor can override the display controller’s behavior.

Disabling dithering via Stillcolor is reported to have fixed the issue for some. Unfortunately, others say it hasn’t worked for them, so your mileage may vary.

Passwords.app and Magic Links

John Gruber:

There are many sites — and the trend seems to be accelerating — that do not use passwords (or passkeys) for signing in. Instead, they only support signing in via expiring “magic links” sent by email (or, sometimes, via text messages). To sign in with such a site, you enter your email address, hit a button, and the site emails you a fresh link that you need to follow to sign in. I despise this design pattern, because it’s inherently slower than signing in using an email/password combination that was saved to my passwords app and autofilled by my web browser.

[…]

To make matters worse, when you create a new account using a “magic link”, nothing gets saved to Apple Passwords. I don’t have many email addresses in active use, but I do have several. Sometimes I don’t remember which one I used for my account on a certain site.

[…]

One workaround I’ve used for a few sites with which I keep running into this situation (Status, I’m looking in your direction) is to manually create an entry in Apple Passwords for the site with the email address I used to subscribe, and a made-up single-character password. Apple Passwords won’t let you save an entry without something in the password field, and a single-character password is a visual clue to my future self why I did this.

I have also run into this friction where the Passwords app insists I not leave the field blank but there’s nothing that really makes sense to put there.

I’d always assumed that sites used magic links because people don’t remember their passwords, and it’s easier to click a link than to go through the password reset process each time. But Gruber notes that magic links are also an effective way to combat account sharing.

Hudlum 1.0

Peter Maurer:

The volume indicator, on the other hand, is most important to me when there’s currently no sound playing, e.g., because I want to confirm my system is muted (or at least not in “yell loud enough to wake everyone in the house” mode) before I start playing a video. And I’d rather do that without having to squint at a tiny slider on a fuzzy-glassy background in an inconvenient spot way outside of my center of attention. A tiny slider on a fuzzy-glassy background in an inconvenient spot way outside of my center of attention, I might add, that doesn’t always update properly when I hit the mute/unmute key.

[…]

Enter Hudlum, the nostalgic retro HUD-style system volume indicator for dinosaurs[…] As silly as it may seem, this helped me make peace with macOS 26.

Backblaze No Longer Backs Up Dropbox

Rob Halliday:

It appeared that Backblaze was now just not backing up Dropbox AT ALL, and was discarding (without warning) existing backups of Dropbox folders.

I contacted Backlbaze tech support. Janet their ‘AI Agent’ who is “well-trained to answer your questions” (!!), responded an hour or so later saying that Backblaze now basically do not back up Dropbox as of a recent update to the Mac Backup software.

[…]

Working back through the Backblaze release notes, this change happened in 9.2.2.878. The release notes page does not include release dates for software versions, so there is no way of telling when this change happened.

[…]

If I hadn’t discovered this by accident today, I might not have found out until too late. I suspect this is why I haven’t managed to find more outcry about it on the web today - I suspect this applies to a lot of people, who know this has been working fine and haven’t yet noticed that it’s now broken. Yes, it’s in the release notes, but a change like this should, I feel, be displayed VERY PROMINENTLY as part of an update, or an update causing a change this dramatic should not be forced on users automatically.

I’ve had concerns about Backblaze for a long time, but this is a new low.
