Open Finder. cmd+Q. Does it quit anything? Nope nothing happens.
Open apple TV. cmd+w -> minimizes window. Open Safari. same keys - cmd+w. Closes current window? Nope. Closes tab. Open Apps. Cmd+w. Does it close window? Close Tab? Nope...third option...does fucking nothing.
That's 3 different apps made by apple and preinstalled by apple...three different behaviours
Cmd-W closes the current *document*. In tabbed apps, the document is the tab.
It is true that Finder is always running, you can’t quit it or kill it.
