Apple Seeds Second macOS Sequoia 15.1 Release Candidate

Apple today provided developers and public beta testers with the second release candidate version of an upcoming macOS Sequoia 15.1 update, with the new software coming one week after Apple released the seventh beta. Apple introduced the first RC on Monday, and there's likely a new version to address an underlying bug.

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. Public beta testers can sign up on Apple's website.

‌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.

Might just be something for the new hardware announcements next week.

Unless they communicate something critical, I'll wait until the official drop. The current public beta RC build is running fine on two of my Macs.

Has anyone else held off updating to Sequoia? I don't want any trouble.
For about a week or two I've been running Sequoia 15.0.1 on a 2020 M1 MacBook Air, a 2023 M2 Max MacBook Pro, and a 2022 M1 Ultra Mac Studio.

So far I haven't run into any issues.

I hope it fixes the iPhone notifications because the first RC broke the feature

I have 15 GB as a download, too. 15 GB????
It will be interesting to see what happens to the downloaded update size when Intel is no longer included.
