I’m sorry but some of the comments are out of touch. Apple devices do not have any intent of supporting separate OSes . Asahi supports M1 to M2. I can see this as a PSA to not install a beta but I am confused who would install both Akashi and macOS 27 beta at the same time when you could run the beta in a VM for development ? Others have said that this has been a fix that will happen soon.

There is clear intent, albeit not as good as the Boot Camp days. One doesn't just accidentally the Boot Policy subsystem to enable doing so every step of the way as it is. It has even been remarked as much by an Apple dev:

> I purposely designed a mechanism so that M1 Macs would retain the capability to boot completely arbitrary code instead of XNU if users wanted. But you have to 1) reboot to recoveryOS with a physical power button press and 2) put in your SEP-backed credentials.

> The challenge to running arbitrary code of course, as @marcan42 noted in his crowdfunding effort to getting linux on the M1, is that the SOC is undocumented, so you still have to reuse bits of XNU and/or reverse engineer a bunch of stuff.

> As one senior architect said "the contract is that there is no contract". So that Apple can change things to suit its own needs, not others', to build the best macOS experience, which is what most customers (besides y'all who follow me) are there for.

12.1 also added support for raw image boot, which was seemingly for, and has only been relevant to, making booting Asahi Linux easier. Discussion at the time https://news.ycombinator.com/item?id=29591578 and an archive of the tweet's content below:

> Looks like Apple changed the requirements for Mach-O kernel files in 12.1, breaking our existing installation process... and they also added a raw image mode that will never break again and doesn't require Mach-Os. And people said they wouldn't help. This is intended for us.
