> In 2011, Apple released Mac OS X Lion which introduced an enhanced scrollbar behavior that made scrollbars hidden by default.
I don't think hiding scrollbars can really be termed an enhancement; 'mistake' at best or 'user-hostile behavior' at worst seem more appropriate.
The original Macintosh GUI succeeded so well because it made it so easy to see what was possible. It laid an awful lot of stuff out right there on the screen in front of the user, and what was hidden was easy to get at. They spent a ton of time testing an improving usability. Modern macOS, OTOH, just doesn't feel right anymore; I suspect it is designed to look good, not to be usable.
