I cannot add or remove apps from the Dock - how do I enable this?
I cannot remove apps or add them to my Dock. When I click on the app, they're in the options menu: Open at Login and Show in Finder. There is no remove from Dock. I cannot drag the apps out of the Dock (even if they are not active - don't have the dot underneath). Please help.
