I mistakenly locked my sys. preferences and now it asks for password to unlock, and of course I don't remember it. I have tried my main password without success and any other password I can think of. I have used the question mark for hint, but no hint appears. My system is a late 2012 mac mini entry-level os 10.8.5. I sure could use some help getting the lock open.
