macOS Tahoe 26.3 Release Candidate Now Available

by

Apple today provided the release candidate (RC) version of an upcoming macOS Tahoe 26.3 update to developers for testing purposes, with the update coming a week after the launch of the third beta. The RC is the version of ‌macOS Tahoe‌ 26.3 that will be provided to the public as long as the final testing phase uncovers no major bugs.

macOS Tahoe 26 Thumb 2
Developers can download the ‌macOS Tahoe‌ 26.3 update by opening up the System Settings app, selecting the General category, and then choosing Software Update. Beta Updates will need to be enabled, and a free developer account is required.

There's no word yet on what's included in ‌macOS Tahoe‌ 26.3, and no new features have been found during beta testing so far.

We'll likely see Apple release ‌macOS Tahoe‌ 26.3 next week.

Tahoe? From the perspective of design, Apple seemingly has entered an era of overfixing and misimproving of what's already proven to be well working. Sometimes you have to leave things as they are, because they are good enough.

Hmm. 26.3 RC seems broken. NSWindow objects with with certain styleMask configurations cannot be interacted with or resized etc. What is happening? How can such major changes in how stuff work (since ages...) happen in a .3 update's RC (even compared to beta3)? Or are these bugs? Either way, this is weird.

Update: I think it's not just me - tried some other apps I know to use some creative UI, they seem to be broken as well + tried an installation on a separate Mac with same results. I hope this is a bug and not a feature, Apple will issue a quick follow-up version with a fix, otherwise some app developers will face a crowd of angry users when ppl start upgrading to 26.3. :)

Update 2: Apple confirmed the issue ('https://developer.apple.com/forums//thread/814798?answerId=875066022#875066022'). Hopefully there will be a fix. It's a very specific problem, most other apps are fine of course but many are affected.

Surprised they released it before announcing the M5 Pro/Max MacBooks. I thought they were holding it back as to not leak info before they’re announced.

I think this might mean we’re going to be waiting a while for the new MacBooks.

overfixing and misimproving
misimproving ftw! How have I never considered, used, or heard of this word before?! I just looked up misimprove ('https://onelook.com/?loc=thes3&w=misimprove') and while some say it goes back to 1913 it also appears in an 1828 dictionary ('https://webstersdictionary1828.com/Dictionary/misimprove') too! Wow, it's a timeless concept I guess! In this age of misinformation and disinformation, where mis- is unintentional and and dis- is purposeful and malicious, this seems relevant.

With that logic: Does disimprovement = enshi✝ification? 🤑 15 years ago I was pretty annoyed (and still am) when Apple stripped the color from Finder's sidebar. I still wonder if it was mis or dis-improvement? Over-zealous Apple UI designer or something more nefarious to drive iCloud services? See Lion’s grey sidebar is a Jedi mind trick ('https://www.brunerd.com/blog/2011/09/27/lions-grey-sidebar-is-a-jedi-mind-trick/')

Anyway "overfixing" is pretty good too but misimproving is gold! 🏅
