When I open System Preferences and click on an item it says 'Loading Users & Groups' at the top of the window, but will not load the pane.

I've tried deleting the property list file:


I also tried clearing the PR and booting in Safe Mode. Anyone have any other ideas before I wipe and re-install?

thanks mcgrailm

Have you looked in the console? Maybe you'll find some error messages there which can narrow the problem down. You can view log files in Console, located in /Applications/Utilities.

Have you tried to check (and maybe repair) the file rights. You can do this with disk utility.

logs says "PreferencePanes folder is missing" I guess that can't be fixed without re install ? – mcgrailm May 23 '12 at 20:46
To be honest i am not sure. Haven't tried to delete my prefs folder :). Maybe you can use Time Machine to restore the folder? – Pfitz May 23 '12 at 20:50
ha good point , doubt they had time machine running but thats a good thing to try thanks for your help – mcgrailm May 23 '12 at 20:52
just checked: directory for system PrefPanes is : /System/Library/PreferencePanes – Pfitz May 23 '12 at 20:54

Boot in single user mode (Hold down SHIFT key right after hitting the power button until the Apple Logo appears), Login, Launch System Preferences, Load the Preferences Pane that is not working, Restart Mac OS X. That worked for me when nothing else did.

Shift is actually Safe Mode, but the rest is certainly worth a try. – Tetsujin Apr 15 '15 at 6:40
