BSD might be an option. But this post is basically meant to ask the following question:
Windows or Mac, which OS do you dislike less?
For me, it’s Windows. Microsoft is shit, but at least there’s some flexibility in terms of how I can use my system and what hardware I can use it on.
Another poster mentioned yabai, but I’d bring up Amethyst as well. The install process is virtually nonexistent, just use homebrew, or drag and drop like any other mac app. It has a whole bunch of tiling modes, but I always just leave put it on Tall (DWM-like) and leave it there.
