I recently downgraded from Mountain Lion to Lion. I erased my internal hard drive, installed Lion, updated to 10.7.4, and then migrated my user account data using the Migration Assistant.

 

I am unable to open the Energy Saver or Desktop & Screen Saver Preference Panes. I get an error message that says "Could not load Energy Saver preference pane."

 

I opened Console.app and this is the error message:

 

9/16/12 2:49:55.975 PM System Preferences: [NSPrefPaneBundle instantiatePrefPaneObject] (/System/Library/PreferencePanes/EnergySaver.prefPane): principalClass is nil.

 

And for Desktop Pane:

 

9/16/12 2:52:58.706 PM System Preferences: [NSPrefPaneBundle instantiatePrefPaneObject] (/System/Library/PreferencePanes/DesktopScreenEffectsPref.prefPane): principalClass is nil.

9/16/12 2:53:05.221 PM talagent: PersistentUI: CSBackupSetItemExcluded() failed with OSStatus -61

 

I have no idea what to make of this! Can anyone help?

 

I have already reinstalled the 10.7.4 Combo Update and deleted the System Preferences preferences in my user account.

MacBook Pro, OS X Mountain Lion (10.8.1)
