Leopard: Unable to Open Keyboard & Mouse Preferences
Posted on Mar 05, 2008 under Mac Tips |You have a problem opening the Keyboard & Mouse Preferences. It just stays at Loading Keyboard & Mouse.
To fix this problem, try the following:
1. Navigate to User/Library/Preferences.
2. Delete the com.apple.systempreferences.plist file.
Now you should be able to access the Keyboard & Mouse Preferences. This will also fix any problems you may experience with function keys on your keyboard such as F1 through F12 not working.

Well, that didn’t work. I deleted the file and tried to access my Keyboard & Mouse configuration. Not only does this not work but the file keeps coming back everytime I try.

Hi there,
I had the same problem. When you delete the com.apple.systempreferences.plist file it didnt work. Instead, rename the file to com.apple.systempreferences2.plist and open system preferences and you should be fine. hope that helps you out.
Good Things,
J
