First time Mac user. I am confused by the fact that the finder application is always open. For example, when switching apps with Cmd+Tab, it is always there, even when there are no windows opened for the app. Cmd-tabbing to Finder with no windows/tabs opened for it has no effect (it seems to me it would more intuitive to open a new tab when this action is chosen).
Furthermore, there is no 'Close app' option when I right click the Finder icon in the dock. Am I misunderstanding something about the Finder app? Is it required for proper functioning of macOS? From what I see, Finder is just a file browser, which by no means should be forced to be open 100% of the time.
explorer.exe
which is also always open on Windowsexplorer.exe
in Windows unless you open the task manager. It is there, but behind the scenes, you don't see it when alt-tabbing.
