Is there a way to have System Preferences asking the password only once to unlock certain settings ? This is an old issue I had. I just recently upgraded to a MBP and after the initial installation I am quite sure it was working as I wished: unlock System Preferences from anywhere and stay unlocked.
Then I did the assisted migration from my old MacBook disk, and now it is back again to always asking the damn password. It seems like there is a quite short time. Yes, i did try checking and unchecking the option in Security & Privacy/Advanced settings. I suppose it could be easily fixed deleting a plist file. The problem is that I can't figure it out which one. Unless I dreamed it could stay unlocked..
