That's hilarious. Remind me, which colour represent “maximize” again? And why are half of the apps I constantly use stuck in a group together such that I have to use a different key to switch between them? And where is the handle to resize a window, anyway?

You only think osx is better designed because you're used to and therefore blind to the various papercuts that osx inflicts upon its users.

- macOS (Quartz): No, you'll need a third-party app.

- Windows (dwm): No, you'll need PowerToys.

This statement of yours is also a bit silly considering Linux desktops have way more in common with macOS than with Windows. They share a whole bunch of concepts like POSIX compliance, use the same shells, and they even share a package manager (Homebrew, which seems to be gaining a bit of Linux popularity lately). Even CUPS comes to mind.
