Looking forward to installing 15.4 or 15.5 around WWDC time, after all these bugs are somewhat worked out... and early adopters have found workarounds for those still lingering. Anyone missing "just works" Apple? I recall the "good old days" where one could wait for .2-.3 and have a pretty stable macOS.

I’m still experiencing the “good old days” of it just works. I roundly reject the idea that Apple’s QA isn’t what it used to be. If anything it’s much better. That argument is pure FUD and I’ve been using Apple gear exclusively since 1982. I've been through it all in the last 40 years. It’s better today, no question.

Sequoia broke screen sharing. If Apple cannot make work what has worked for 15 years then I do not have a lot of hope for Apple Intelligence. macOS 15 struck me as a beta, really awful.

The download last Monday that updated Sonoma to Sequoia seems more like beta software that non-beta. Apple rushed it out the door.
Not at all. Apple explained precisely the roadmap for upcoming features. The negativity is misplaced entirely.
