Operating systems are different though, since their whole purpose is to host _other_ applications.

FWIW, MacOS isn't any better or worse for security than any other desktop OS tbh....

I mean, MacOS just had it's "UAC" rollout not that long ago... and not sure about you, but I've encountered many times where someone had to hang up a Zoom or browser call because they updated the app or OS, and had to re-grant screenshare permissions or something. So, not that different. (Pre-"UAC" versions of MacOS didn't do any sandboxing when it came to user files / device access)
