Didn't the Best Koreans rip off the Mac GUI in their home-grown spyware-laden Linux distro? Red Star Linux or whatever it's called.

I wonder if they have a GitHub...

I haven't downloaded or played with it because I'd rather not toy with software so obviously full of landmines, but from what I've seen it also falls into the "surface level" bucket. It goes a little further than one might get by e.g. enabling KDE's global menubar and installing one of the Mac-themed Breeze forks, but not much.
