Windows can be controlled entirely by the keyboard, out of the box (Start+ArrowKey).

MacOS always required extra setup with Karabiner and other tools to mostly accomplish the same thing.

The BSD derived base in MacOS made a great developer OS but the windowing system often felt lacking.

macOS has full keyboard access and you don’t need Karabiner to enable it.

It's my understanding that MacOS requires extra setup for those shortcuts regardless of Karabiner.

If you feel that extra setup is acceptable then any almost modern OS will fit your needs. There's something to be said for standardized shortcuts that work on every MS Windows instance.

All you need to do is enable full keyboard access in System Preferences -> Accessibility and it'll work.

Which keyboard combination moves windows around, the same as WIN+ArrowKey, after enabling "keyboard access" in MacOS?
