macOS has its own share of UI quirks too. The volume slider is fine, but app management is surprisingly bad for a platform that prides itself on UX. There's still no native way to quit all apps at once, and Activity Monitor feels stuck in 2005. Small UI tools that just get one thing right tend to stick around.

MacOS requires there to be an App as First Responder - what app should be that if you quit all apps?

The nearest that makes sense is Log Out.
