Dock.prefPane error loading in Snow Leopard

Apr 1, 2010 - 2 Comments



“The document ‘Dock.prefPane’ could not be opened. System Preferences cannot open files in the ‘Mac OS X Preference Pane’ format.”

Oh that makes perfect sense, a default preference pane can’t be opened by the System Preferences? What??

Maybe this is an April Fools joke from System Preferences… but a reboot fixed it.
