Why the red X doesn’t quit apps on a Mac
The red button in the top-left corner of a Mac window closes that window. It has never quit the app, even though it looks like it should.
What the three buttons do
Every Mac window has three coloured buttons in its top-left corner. Hold the pointer over them and you’ll see their symbols.
- Red (×): close. Closes this window. The app keeps running.
- Yellow (−): minimise. Sends the window to the right end of the Dock.
- Green: full screen. Fills the screen. Hold the pointer over it for options to tile the window.
None of them quits the app. Quitting is ⌘Q, or the app’s name in the menu bar → Quit.
Why it was designed this way
On a Mac, the app and its windows are separate. The red button belongs to the window, so it closes the window. The app’s menus are in the menu bar at the top of the screen, and they stay there after the last window closes, ready for a new document. See why Mac apps keep running for more.
How to tell the app is still running
After you click the red button, look at the Dock. If the app’s icon has a dot under it, the app is still open. Its name also stays in the menu bar while it’s the app in front.
Make it automatic with Exeunt
Exeunt is a small menu bar app that does one thing: when you close an app’s last window, it quits the app. You keep closing windows the way you already do, with the red button or ⌘W.
- Your work is safe. Exeunt never closes a window and never force-quits. It asks the app to quit the same way ⌘Q does, so an app with unsaved changes shows its usual save dialog.
- You choose the exceptions. Mail, Messages and music apps are useful with no window open. Add them to the never-quit list with one click from the menu bar.
- System apps are protected. Finder, the Dock, System Settings, Control Centre and Notification Centre are never quit.
It runs on macOS 13 or later, on Apple Silicon and Intel Macs. Free for 14 days with no account, then a one-time $5.
If it’s specifically the red button you want to quit apps, Exeunt has a setting for exactly that: clicking the red button quits the app, even if it has other windows open, while ⌘W still just closes a window. Exeunt tells the two apart after the window has gone, so if you click the red button and then cancel a “Save changes?” dialog, nothing quits.

Questions
Why doesn't the red X close the app on a Mac?
The red button closes the window it belongs to. On a Mac, the app keeps running after its windows close, until you quit it with Command-Q.
What do the red, yellow and green buttons do on a Mac?
Red closes the window, yellow minimises it to the Dock, and green makes it full screen. None of them quits the app.
Can I make the red button quit the app?
Not with a macOS setting. Exeunt can: in its red-button setting, clicking the red button quits the app, while Command-W only closes the window.
