macOS Tahoe 26 RC
Apple today provided developers and public beta testers with the release candidate of macOS Tahoe 26 for testing purposes, with the RC coming after nine rounds of betas.
Who can tell from the release notes what’s changed in the last few builds?
I don’t honestly know why Apple provides OS release notes to developers, because it doesn’t remotely reflect either the known issues or the fixes/changes build to build. It’s like some tiny subset of the issues known internally before WWDC, and whether they fixed them or not since (spoiler: most of the bugs that were mentioned in the release notes doc in June are apparently still present)
iOS 26, iPadOS 26, macOS Tahoe 26, tvOS 26, watchOS 26, and visionOS 26 will be released to the public on Monday, September 15, Apple announced during today’s “Awe Dropping” Apple event.
Time to start taking screenshots for my app releases.
I was not prepared for macOS 26 on Sep 15.
it is not ready. it is definitely not ready. please don’t ship it like that.
just yesterday, I had a laugh at how SwiftUI layout is broken on macOS 26, in entirely new ways. But I assumed they still have few months to fix it.
The OSes included in the Xcode 26 release candidate are ‘basically’ the same as the beta 9 seeds. I think a huge pile of bugs are about to ship; macOS and visionOS especially are in a really bad state right now.
yep found some last minute bugs… the textbox is literally hidden on Mac Image Playground and look at how the sidebar behaves when running an iOS app on macOS lol (in my next reply), sadly couldn’t test those on a VM
So yeah, #macOSTahoe killed all my apps.
PDX Transit for macOS, in the 7 years as an #AppKit app, the toolbar & sidebars worked perfectly. Now the toolbar just gets fucked up when you switch tabs AND the inspector sidebar now fails to remember its position between launches.
As for all my Music-related apps. They no longer work because Apple Music sends far less info in the NSDistributedNotificationCenter dictionary.
So yeah, I’m done. I am taking these down. I’m not having fun anymore.
And also this. All of my #AppKit bugs I’ve been reporting since Beta 1 were mostly not addressed and around Beta 6 or 7[…] No way will I take the hit for Apple’s bugs. They worked fine for the better part of 7/8 years and broke as of #macOSTahoe beta 6 or 7. I logged bugs in Feedback app.
Even after using Tahoe for months, I’m still regularly struck by something on my screen that I instinctively interpret as some kind of graphical glitch only to realize that it’s “working as intended” and that someone thought this design was a good idea.
For example, check out the weird smudges at the top of this Finder window. Surely some kind of error, right? But then you notice the text competing with the window title. And then you connect the text to the smudges and realize what’s going on.
This is not a “staged” screenshot, BTW. This is something that organically appeared on my screen while using my Mac with Tahoe RC, and my legitimate reaction was to do a double-take because it looked like an error to me.
macOS Tahoe will be the first release to support Repair Assistant, adding the ability to install calibration data to complete repairs.
[…]
For Mac repairs through the self service repair program, this will allow used parts and previously replaced parts that were not calibrated to be calibrated to ensure the best reliability and security standards are met.

Guzmán’s approach is correct: stop developing for Apple’s platforms. Develop for the open web or linux/bsd.
Unpopular opinion. I gotta say, despite my reluctance I took the plunge and I don’t hate it.
Thing is, the bar was already pretty low. I’ve gotten used to weird behavior and inconsistency and bugs just like on Windows, so it’s not like what I had was perfect.
None of my apps broke, in fact a lot of the most important ones RC day one updates specifically to support it, even some that hadn’t been updated in a while.
It probably was not fun for developers but they seem to have managed to ship something that works at least as well as macOS does.
It’s about as buggy as any RC/.0 release, actually made some improvements, didn’t break anything. It’s a lot more annoying on the phone actually.
