Why is the Finder app always open?

Question

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 Mac OS? From what I see, Finder is just a file browser, which by no means should be forced to be open 100% of the time.

Answer 1

The main reason it's always open is that it displays the icons on the desktop. You can check what the finder does by enabling the "Quit" menu feature. To do this, launch the Terminal application and enter the following commands:

defaults write com.apple.finder QuitMenuItem -bool YES

Hit return. Then restart the Finder by running

killall Finder

Close the Terminal. Click on the Desktop, choose "Finder" in the top bar, and "Quit Finder". Now you're running without Finder. First thing you'll notice is that all Desktop icons will be gone.

To get your desktop icons back, just click on Finder in the Dock.

If you want to remove the "Quit Finder" menu item, you can do that with:

defaults write com.apple.finder QuitMenuItem -bool NO

Answer 2

It's not only a "file browser", but it's responsible for quite a bit of GUI functionality such as the Desktop, following paths and connecting to servers. Finder is always running, and a launch service will relaunch it if it is quit unnaturally. Much like File Explorer (explorer.exe) on Windows, you shouldn't quit it. Quit functionality can be added back to Finder, but you really shouldn't unless you have a very good reason for it.

Answer 3

Think of the background process for Finder akin to that of the 'Windows Explorer' background process on Windows. As mentioned above, it is essential for the MacOS UI & GUI elements on the desktop. If you are new to Mac, take a look at the Activity Monitor App in your Utilities folder. This is essentially the Mac equivalent to Task Manager on Windows and can help organize/debug processes in the background.

Answer 4

For myself, I found a good way to use the CommandQ shortcut in Finder.

You can configure CommandQ to close all Finder windows, as it does for other apps (except quitting Finder) as follows:

1. Open System Preferences > Keyboard > Shortcuts > App Shortcuts
2. Create a new shortcut as follows:
   Application: "Finder"
   Menu title: "Close All"
   Keyboard Shortcut: "Command Q"

Note that the original shortcut, CommandOptionW, will stop working.
