Asahi is pretty cool, any chance you've tried it on m2? I checked out the feature matrix. As I understand the CPU is doing the work currently and the GPU is unsupported, which leads to quite a bit of battery consumption. Very excited to try it nonetheless.

The m2 is a great piece of kit, I never realized how disruptive heat, vibration, and fan noise was until they were gone. I'm actively trying to put together a fanless desktop similar to the openbsd fanless desktop that is posted here from time to time. https://jcs.org/2021/07/19/desktop
