This is interesting, there was a speech at CCC a week ago or so, that one of the main devs of asahi linux is about to add USB4/thunderbolt support, for M1/M2 series, and soon also M3/M4. Then it’s almost feature complete support (maybe except some coprocessors like AIAIAIAI or video encoding). It’s a real OS alternative then, if macOS will be soon completely messed up by Apple, adding nonsense AI bloatware, killing RAM, SSD and CPU for this bs. And it already performs better in some tests. Might be great for development. I will consider switching.
Just very sad again how Apple does not provide any hardware information or base drivers at all. Typical Apple stupidity, since you can’t make a lot of profit in a short time with a free OS. What a shortsighted perspective. But this seems to be a general problem these days, big corp decisions are made by not very smart and very greedy people.
