If it did not work for you, try pasting "defaults write com.apple.dock mcx-expose-disabled -bool FALSE && killall Dock" into terminal and hitting enter. It was not included in the video because I found this very recently. Hope it works.
Hello Guys, in this video I will show you how to fix your mission control if it is not working. Once I used a lockdown browser for a test and it just stopped working. (Click read more for Instructions) I couldn't find a fix on YouTube so I ended up going to the apple store. They didn't fix it too. I searched it up on google and quite a long time later I found a way to get rid of the lag on the dock, which includes the process of resetting it. I tried the resetting process and it did indeed fix my mission control.
=============
Steps:
Method 1:
1. Open terminal
2. Copy this command and paste it into your terminal: "KillAll Dock"
3. The spacing and capitalization has to be exactly the same as this or else it will not work.
4. Click enter. You will see your desktop flash black and back. After it flashes back, the process is done.
5. Now try mission control
-------------------
Method 2:
1. Open Activity Monitor
2. In the search bar, enter "Dock"
3. Click dock and then click the cross on the left top corner of the app
4. Click "Quit"
5. You will see your desktop flash black and back. After it flashes back, the process is done.
6. Now try mission control
