That's a big if. Mac OS X only supports AMD cards and AMD didn't provide a Radeon driver yet for the M1. It's not clear what is going on, we know the amdgpu driver works an arm64 just fine https://news.ycombinator.com/item?id=20404547 and that contains the most hairy bits namely starting the bastard so I can't see what the hold up can be.
