Mac Multiple Desktops Not Working? Five Fixes, Fastest First

12 November 2026

The short answer

Nearly every "my desktops stopped working" has one of five causes: the keyboard shortcut is unticked, the trackpad gesture is off, each display has its own desktops, Stage Manager is hiding them, or the Dock process needs a restart. Work down the list below; most people are done at step one or two. Once they work again, give them names with DeskStag, so the next time something is off you can see it at a glance.

If you are setting desktops up for the first time, start with How to use multiple desktops on Mac.

Fix 1: the shortcut is unticked

Control and the arrows do nothing? Open System Settings, Keyboard, Keyboard Shortcuts, Mission Control. Make sure "Move left a space" and "Move right a space" are ticked. If you use Control and a number, those tick boxes are here too and only exist for desktops that exist. A keyboard shortcut set by another app can also claim the same keys; the list shows a yellow warning when two clash.

Fix 2: the gesture is off

The swipe between desktops is a setting, not a given. System Settings, Trackpad, More Gestures: "Swipe between full-screen applications" needs to be on, set to three or four fingers. Check "Mission Control" on the same page. If you use a Magic Mouse, it is System Settings, Mouse, More Gestures, and the swipe is two fingers. A third-party mouse driver can take the gesture over.

Fix 3: each display has its own desktops

With two screens, desktops you made on one display do not show on the other. That is "Displays have separate Spaces" in Desktop & Dock, under Mission Control, and it is on by default. Swiping on the second screen moves only that screen's desktops. If you want one row of desktops across both displays, turn it off; macOS asks you to log out and in.

Fix 4: Stage Manager is in the way

Stage Manager groups windows on one desktop and tucks the rest to the side. People turn it on from Control Center, forget, and then think their desktops have gone. They have not. Click Stage Manager in Control Center to turn it off, or in Desktop & Dock. Desktops and Stage Manager can run together, but the view is confusing until you know which one you are looking at.

Fix 5: restart the Dock

Mission Control and the desktops belong to the Dock process. When switching stalls, the animation sticks, or Mission Control shows a blank bar, restarting the Dock usually clears it without a reboot. Open Terminal and run:

killall Dock

The Dock disappears for a second and comes back. Your desktops and windows stay where they were.

When it is not broken, just unreadable

Many "not working" reports are really "I cannot tell which desktop I am on". Mission Control labels them Desktop 1, Desktop 2, and the wallpaper thumbnails look the same. DeskStag puts a name and a colour on each thumbnail, keeps them through reboots and reorders, and flashes the current desktop's name on screen with Control Option Command N. If the desktop you expect is missing, the names show you at once. It runs on macOS 13 and later and asks for one permission, Accessibility.

FAQ

My desktops vanished after I unplugged a monitor. They folded into the remaining display. Plug the monitor back in and they return. With "Displays have separate Spaces" off they would have stayed in one row.

Switching works but a window will not move. Drag it in Mission Control onto the target thumbnail, or use DeskStag's Control Shift and the right arrow to carry the front window to the next desktop.

Do I need to reinstall macOS? Almost never. The five fixes above cover the cases we hear about.
