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.

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

Comparison of MacOS 15.1 RC to previous MacOS 15.1 Beta 7

macOS 15.1 RC (24B82)

* Safari Version 18.1 (20619.2.8.11.9)
* System Firmware Version: 11881.41.5 (M1 based Macs)
* Darwin Kernel Version 24.1.0: Thu Oct 10 21:05:14 PDT 2024; root:xnu-11215.41.3~2/RELEASE_ARM64_T8103 arm64

macOS 15.1 Beta 7 (24B5077a)

* Safari Version 18.1 (20619.2.8.11.9)

Apple Music/TV is still 1.5.1.24 , no change.

Notice how we won't have any chance of a RC2 because nothing really changed with the RC and beta 7.

Looks like installing this over the previous beta erased all my Safari cookies lol
That's why Apple Intelligence is two years behind the competition.
