Here is everything you need to know:​

- You get to choose if you still want to get macOS 15.0 or macOS 15.1 in Settings > Software Update > Beta Updates

- It is currently Apple Silicon only
- I do not know when it will be available on Intel quite yet, but my guess is once macOS 15.0 releases to everyone.
- Apple Intelligence is for the United States only.
- Apple recommends that if you are not using Apple Intelligence to say on 15.0 as that will still be getting beta updates.

Anyone noticing any differences between this and the latest 15.0 beta? (Besides Apple Intelligence of course)
