While it's awesome that it runs there doesn't seem to be GPU support yet as the screenshot reports the llvmpipe software renderer. From what I understand there are significant difference between the M2 and M3 GPUs so this unlikely to be implemented soon. Unless it turns out this original analysis turns out to be wrong.

Personally I don't consider it "working" as a laptop on an Apple M3 unless you actually have GPU support. Software rending just sucks, even with a SoC as powerful as the Apple M3.
