The Mac's System Preferences panels have a universal "lock" icon which, when locked, will apply to all panes, therefore preventing the user from changing any settings until they unlock the System Preferences by typing in their admin password.

I like to keep it locked at all times. However, whenever I restart my computer, System Preferences unlocks itself.

How do I keep the lock setting locked even after a restart?


Go to Security & Privacy, then Advanced.

check the box for Require an administrator password to access locked preferences

That should ensure all the lockable prefs default to locked.

  • Thanks I'll try that. If it survives a restart, then I'll mark this as Answered. – Gary Mar 12 '13 at 17:58
  • Thanks that worked. I had to do a restart to check first because I've had other System Preferences problems before and thought that this problem might be related to those problems rather than this checkbox. But in this case, the checkbox did the trick. – Gary Mar 12 '13 at 20:55
