I do all my gaming and LLM inference on devuan. (That laptop should chew through 30-120B parameter LLMs, depending on how much RAM it has.)

I don't have any of the problems mentioned by you or sibling comments, full stop.

Up until about a year ago, audio was janky as hell, but then as part of the great de-Poettering, they switched from PulseAudio to PipeWire. I've had zero issues since then.

Copy paste works. Login works. X11 runs at native panel speed (144Hz) with bug-for-bug parity with windows 3d acceleration, but open source (AMD drivers). XScreenSaver works (and can lock the screen). I can't comment on any of the stuff you mention in the second paragraph. I assume it's a bunch of broken Wayland workarounds?

Anyway, instead of switching to Mac, just switch to a stable distribution. Devuan is Debian minus systemd, so essentially everything works out of the box. Even crap that requires systemd usually works, since they install stubs. LLMs like Claude will happily admin it once you tell it that which init system to target.
