Mission control consistently, but randomly stops working

I experience the same issue randomly with my M1 MBA and the only solution I found was to kill Dock from Activity Monitor.

To do so, simply:

1. Press Command + Space to open Spotlight, then search for Activity Monitor and press return to launch it.
2. Use the Search bar in Activity Monitor to look for Dock.
3. Select Dock and then click the 'x' icon in the title bar and select Force Quit.
4. The Dock process should re-launch automatically and Mission Control is its child process and should now function as expected.

Hey there, jag4jag.

It appears that Mission Control becomes unresponsive on your MacBook Pro and restarting only temporarily helps. To begin, you can see if there are any macOS updates for your MacBook Pro: How to update the software on your Mac

To isolate this issue further you can also start up your MacBook Pro in a test user: Set up users, guests, and groups on Mac This step can show if an issue is happening in a specific user only or multiple users.

Another step you can take is to start up in safe mode and test to see if the issue happens there too. Safe mode only allows certain software to load, which can help us isolate this further. You can read more about that here: How to use safe mode on your Mac

Take care.

Had the same issue today on my new M1 iMac. Between that and System Preferences being a hot mess (UI glitches, not applying setting changes, forgetting which downloaded desktop background is set), I gotta say, I’m not exactly thrilled with the MacOS team’s QA.

There is probably a software conflict of some sort.
