I am using OS X El Capitan. For some reason, I can no longer unlock the preferences in System Preferences panes although I still appear as an admin. When I enter my password for authentication it simply goes back to the locked mode again. How can I fix this?

  • How long does it take to lock again? Does it not open in the first place, or does it stay, and then after a short while locks again? Also, I don't know if Repair Disk Permissions In Disk Utility could work... – TheBro21 Oct 16 '15 at 18:30
  • it doesn't unlock at all. And I don't remember having changed the system preferences lately – José Quenum Oct 16 '15 at 18:36

    @TheBro21 Repair Disk Permissions is no longer available in Disk Utility. – grg Oct 16 '15 at 18:36
