Even though the M1 and M2 chips in modern Macs are based on ARM processor designs, they aren’t like any other ARM designs. That has made porting Linux to new Macs a difficult challenge, but there has been some impressive progress recently.
Much of the work around porting desktop Linux to Apple Silicon (M1 & M2) Mac computers has been under the Asahi Linux project, which already offers a desktop distribution that can boot natively on many models. Even though Linux has supported ARM chips for years, largely due to Google’s use of Linux for the Android kernel and devices like the Raspberry Pi, making everything work on Apple Silicon has been a challenge.
The core operating system and desktop experience has been working on Asahi Linux for a while now, so some developers have moved onto proper graphics support. Alyssa Rosenzweig helped reverse engineer the GPU in the M1 chip to create a user space driver, based on documentation work by Dougall Johnson. However, a kernel-level driver was still missing — a task taken up by VTuber Asahi Linya.
