Unable to change mouse settings in System Preferences
Hello.
I have a managed user account where I want to change the mouse settings (for a standard USB Apple mouse) in System Prefs. I want to change the right click from "primary button" to "secondary button".
However, after making the adjustment and exiting System Prefs the setting reverts back to the default (primary button). So when I reopen System Preferences, the "secondary button" is reset to "primary button".
The managed settings for this account do not restrict System Preferences. It is only setup to stop the dock being modified.
I've tried deleting the com.apple.systempreferences.plist and com.apple.systempreferences.plist.lockfile in users/*account*/LIbrary/Preferences without luck. I've also reset the ACLs for the user also with no luck. If I create a fresh account then the problem goes away. Unfortunately I can't just create a new account in this instance.
Has anyone else has this issue and found a resolution?
Many thanks in advance,
