Because over time I realized Linux wastes a lot of my time on unimportant shit. Then I was given a Mac and eventually I realized that macOS has most of the upsides of Linux while being much more stable, less buggy and more pleasant to use. It just works®™
I don't regret ever using Linux tho, it's a great for learning new stuff and acquiring different kind of thinking. Everyone who's a programmer or in some adjacent field should use Linux at least for a while. It's easy to notice when someone never used it.
Linux is far better for gaming than Mac these days. Proton is amazing, and I have yet to find a game (that my laptop meets the minimum requirements for) that hasn't worked. The most I've had to do is switch from regular Proton to GE-Proton.
Yeah, Mac is pretty meh for gaming, but when I want to game I just use GeForce NOW. It makes gaming on Mac a non-problem and actually turns out much cheaper for me than buying a gaming rig.
