> Supported processors - M1 and M2, not M3 or M4

The M2 models came out in 2022. You can't buy them new anymore.

Asahi linux doesn't support any of the currently sold macbooks, so I think it's fair to say modern macbooks don't run linux.

This is also at Apple's mercy, if enough people do it there's a non-zero chance they lock things down further. They've done even more consumer-unfriendly things before.

Looking at the support page, that comes with a lot of asterisks still.

Not really, it's a nice tech demo at best.
