Apple Seeds Fifth Developer Beta of macOS Sequoia 15.1

by

Apple today provided developers with the fifth beta of an upcoming macOS Sequoia 15.1 beta, with the new update coming a week after Apple released the fourth beta.

macOS Sequoia Feature
Registered developers can opt-in to the macOS Sequoia beta through the Software Update section of the System Settings app. An Apple ID associated with an Apple Developer account is required to get the beta.

macOS Sequoia 15.1 introduces the first Apple Intelligence features, adding support for Writing Tools, new Siri features, Smart Replies in Mail and Messages, Priority messages in the Mail app, Memory Movie and Clean Up in Photos, and more.

The update does not include Image Playground, Genmoji, or more advanced ‌Siri‌ functionality.

Using Apple Intelligence features requires a Mac that has an Apple silicon chip.

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.
