Asahi Linux is a project and community with the goal of porting Linux to Apple Silicon Macs, starting with the 2020 M1 Mac Mini, MacBook Air, and MacBook Pro. More details here https://asahilinux.org/about/.
Asahi Linux is still in very early alpha stages. Lots of hardware components are not functional yet! Check out the Feature Support page first, and if you still want to give it a go, see the blog post for the alpha installer:
The alpha release https://asahilinux.org/2022/03/asahi-linux-alpha-release/.
All the code is on GitHub https://github.com/AsahiLinux.
Comparing the M2 MacBook Air
I've updated the pages comparing the new Apple Silicon machines with those with the older Intel chips https://www.macinchem.org/reviews/MacBooks/m1macbookpromax.php. In addition to the MacBook Pro M1 Max I've now added the M2 MacBook Air.
