Short answer

On Mac, the red button closes the window but the app keeps running in the Dock. With Tuno, closing an app’s last window with the red button quits the app completely.

In macOS

macOS keeps apps open after their last window closes so they can reopen quickly. To quit, you press ⌘Q or choose Quit from the menu.

With Tuno

  1. 1

    Open Tuno and allow Accessibility.

  2. 2

    Turn on “Quit the app when its last window closes” in Tuno › Windows.

  3. 3

    Click the red button on an app’s last window: the app quits.

macOS 15 or later, Mac with Apple silicon.

Frequently asked questions

What about unsaved documents?

If an app asks to save, the window stays open and the app doesn’t quit until you answer.

Does ⌘W also quit?

No. Only the red button quits the app; ⌘W keeps working as usual. Finder is never quit.
