Do you use a MacBook with an external monitor and have the issue that the dock keeps moving to the other screen?
Apparently, this is not a bug but a feature.
Apple designed the Dock to move where you “need” it.
If you want to force it back to the MacBook main screen, all you have to do is to go back the the screen without the dock, and move your mouse to the bottom of the scree trying to drive it outside the screen.
The dock will magically appear on that screen.
