I recently updated my computer from Mavericks to El Capitan, and I'm unable to add or remove items from the dock. If I attempt to change the dock, the computer freezes and I am unable to interact with the computer through the GUI.
The machine has multiple users, and I am the only user on this system that has this problem. I suspect that it's an issue with the way my dock is configured. Is there any way to "factory-reset" the dock? Failing that, is there any way to fix a dock that can't be modified?
