No new features were found in the first three ‌macOS Tahoe‌ 26.5 betas, and it's likely the update primarily focuses on bug fixes and performance improvements.

Went back to Sequoia from 26.4 today. 🤮 Please wake me up when 27.8 will come out.

I hope somebody is working on Finder

I swear there are memory leaks in Tahoe Finder.
Unfortunately, I think Apple's dedicating too much time to pushing out new shiny features in general, and not enough time in fixing bugs. macOS 15.7.5 is having so many issues with Bluetooth, audio, Safari, and overall performance, that I'm going to have to wipe and downgrade to 15.4 if they don't have it resolved in the next month.

Why, when Apple releases a new OS, do they need to fix things that were already working fine?

For example, if Bluetooth issues were fixed in macOS Sequoia, why are they broken again in macOS Tahoe?

You get my point? it feels like releasing a new OS is like breaking everything that was already fixed. I don’t get it.

I'm contemplating this exact thing.
I just snagged an M4 Mini again this morning.

I've been having so many strange issues with Finder in Tahoe that I'm not sure I can do it anymore.
