Mission Control not working (Mac OS Catalina 10.15)

catalinamission-control

I'm running Mac OS Catalina 10.15 and all of a sudden my favourite feature, Mission Control, has stopped working. It does not work with the touchpad gesture, touchbar, Apple Keybpoard or even my Apple Mouse. I've seen other articles for earlier issues where you update hot corners and/or use "Killall Dock" but none of these made a difference.

Any ideas?

Try to restart the Mac's Dock, follow this link fix the problem for me:

https://www.defaults-write.com/fix-for-not-working-exposemission-control/

To solve this problem apply the following defaults write command:
defaults write com.apple.dock mcx-expose-disabled -bool FALSE
Restart the OSX Dock:
killall Dock

MacOS – Hot Corners for Mission Control stop working

Had this issue November 2016 running OS 10.12.1 "Sierra" an additional symptom is that Mission Control was not launching. I fixed it by opening Activity Monitor, Quit the dock (force quit was not necessary). Went back to normal

MacOS – OSX Yosemite – Mission Control stopped working

(This irritating bug seems to be biting me more often after updating to 10.10.4)

When this happens and I don't want to have to reboot, I only restart the "Dock" process and the problem is gone. There's probably some GUI way to do it, but I just drop into Terminal and do:

killall Dock

But before that, run killall -s Dock to see what would be killed, to make sure it's only going to directly kill the one "Dock" process.

Once you run killall Dock, Dock will restart in a few seconds and then Mission Control is working again. You can verify that the restart happened by checking the Process ID of "Dock" after the restart.
