maybe missing out on a few games but that is probably a tie with Linux

As some one who runs both: no, not even close. Mac has more direct ports than Linux true, but proton vastly outweighs that. I have dozens of games that show up on steam on my mac as unplayable where as I dont have any that wont run under proton.

Five years ago you’d probably have been right, but Linux is far superior to OSX for gaming now.

(E: assuming you’re talking about an apple silicon macbook, IDK the status of proton on x86 macs maybe it works there?)
