Over the last few weeks, I’ve had a few instances of weird behavior my Mac:
- Gestures to move between Spaces are ignored
- The Command+Tab interface won’t show when invoked
- Mission Control gestures are ignored
Thankfully, the fix is easy enough. There’s no need to restart to bring these features back. In Terminal, the killall Dock command will restart the Dock process, which is apparently in charge of all of these features.
I thought this was a weird bug in macOS Monterey, perhaps as a side effect of my recent migration from a 2019 Mac Pro to my new Mac Studio. Then on yesterday’s episode of Upgrade, I heard Myke come across the same bug. He was able to invoke it by making changes in the General preference pane in System Preferences:
Myke found it on an M1 iMac that has been set up for months, so I bet this is just a bug in the current version of Monterey. I’m not convinced that going into this preference pane is the only way to trigger the bug, but it’s a sure-fire way to produce the problem. Hopefully macOS 12.4 resolves it.
