I also have a Thinkpad, but an X1. I'd trade it and my first-born child to get to run Linux on a modern MacBook.
No offense to Lenovo, it's a great laptop. But Apples build quality is on another level, plus if I want to run local LLMs, AFAIK there is no better option.
There's no way I'm going back to macOS though, that shit was bad 5 years ago when I switched and it sounds like it's gotten way worse.
