Asahi linux effectively only supports the M1 and M2 chips, so even a modern macbook air won't work, and even on "supported devices" you can't use thunderbolt or a usb-c display yet.

These use the A series chip, and even supporting new M chip revisions has been enough of an undertaking that I wouldn't really expect this to get Asahi linux anytime soon....

And apple can lock down the bootloader to be closer to the iPad/iPhone at any time with no notice, and based on their past actions, it would be quite in-line with their character to do so.

The Asahi folks have also demonstrated M3 support, though without GPU-accelerated graphics (the M3 GPU is very different from the M1 or M2). Much of the effort is currently on getting the existing components upstream.

By “past actions”, do you mean doing extra work to make the bootloader support other operating systems? https://asahilinux.org/docs/platform/introduction/
