Reset Mission Control on Mac
An effective way to fix Mission Control not working on Mac is by resetting it. To do it, you need to kill the Dock, as it's the parent process of Mission Control. You can either use Activity Monitor to quit the Dock process or execute a command in Terminal. We'll show you how to reset Mission Control on Mac via Terminal as it's much faster:
- Launch Terminal from Finder > Applications > Utilities.
- Copy and paste the following command and hit Enter.killall Dock
The Dock and its subprocesses like Mission Control will restart automatically. This should solve all kinds of Mission Control issues, including windows disappearing in Mission Control. You can try activating Mission Control again to see if the issue is resolved.
Enable Mission Control and kill Dock
If killing the Dock doesn't work, you can add an extra command to enable Mission Control first. The command will activate Mission Control by modifying the preference file of Dock (com.apple.dock.plist) located in ~/Library/Preferences.
How to fix Mac Mission Control not working:
- Open Terminal.
- Input the command below and press Enter to enable Mission Control.defaults write com.apple.dock mcx-expose-disabled -bool FALSE
- Execute the following command to restart Dock.killall Dock
Hopefully, you no longer face macOS Mission Control not working after applying this fix. If not, move on to the next solution.
Restart your Mac
If you can access Mission Control with the function key F3 or other keyboard shortcuts but find the Mission Control gesture not working, your Mac likely has a small glitch that a reboot should fix. Restarting your Mac also helps clear your Mac's memory and start it fresh.
Reactivate Mission Control Hot Corners
If the Mission Control Hot Corners is not working, you can disable the Mission Control action in Hot Corners and then enable it. To do it, you need to open System Preferences > Mission Control and select Hot Corners. Then change the corner assigned to Mission Control to ( - ), click OK, and reenable it.
Check if the key is working as expected
A malfunctioning key is also a possible reason for the Mission Control keyboard shortcut not working on Mac. To check whether the key functions, you can utilize the keyboard viewer, which you can access by right-clicking the input menu icon at the top-right side of the menubar.
Once the keyboard viewer shows up, you can click the function key or keyboard shortcut to see whether it opens Mission Control. If it does, or the keys in Keyboard viewers are surrounded with orange outlines, the physical keys are likely dead. If it doesn't, you can change the shortcut with another combination in Mission Control settings or try other ways to access it.
Change Mission control keyboard shortcut
If you find the keys for the configured Mission Control keyboard shortcut not working, try changing the combination to another one by navigating to System Preferences > Mission Control. Then click the box next to Mission Control to choose another shortcut.
Use another way to activate Mission Control
Here are all the ways to trigger Mission Control on Mac. If you haven't used all of them, try if you can access Mission Control using one of them.
- Press the F3 key.
- Press Control + Up or your customized keyboard shortcut. (Check in System Preferences > Mission Control)
- Swipe up using three or four fingers, depending on your customization. (Check in System Preferences > Gesture)
- Launch the Mission Control app in the Applications folder.
- Move your cursor to a set corner if you have configured a hot corner for Mission Control. (Check in System Preferences > Mission Control > Hot Corners)
Fix Mission Control issues with Logitech keyboard and mouse
Many users have found Mission Control not working on Monterey with Logitech keyboard and MX Master 3 mouse(or other versions). If that also happens to you, try these fixes:
- Assign a "Keystroke Assignment" to your desired button through the customization feature on Logi Options. You can do it by opening the Mouse section, choosing "Gesture button" and "Custom," then clicking Customize again. After that, click "Keystroke Assignment" twice and enter Ctrl + Up arrow as the keystroke as it's the default keyboard shortcut on Mac.
- Disable "Logic Options Daemon" and "Logi Options+" if the mouse button isn't working. To do it, navigate to System Preferences > Security & Privacy > Input Monitoring, and uncheck these apps.
- Change the Mission Control shortcut from F3 to Fn + F3 if the Mission Control button works inconsistently. To modify the shortcut, you need to open System Preferences > Keyboard > Shortcuts and select Mission Control.
- Turn off Universal Control by opening System Preferences > Displays, clicking Universal Control, then unchecking all the settings.
- Close VirtualBox if you have it running.
- Uninstalling Logitech Options or Logi Options and restart your Mac.
Unfreeze Mission Control
If you are experiencing Mission Control not working on an external monitor, try disconnecting the monitor, closing the lid, and letting it sleep, then waking your Mac from sleep. Test if Mission Control works now. If it functions correctly, you can reconnect the monitor.
