Hi everyone, If I click on the clock and go to Open Date & Time Preferences, I can't do anything until I click the lock icon and enter my password. This wasn't always the case; I think one of the updates did it. Does anyone know how to stop this from happening? Thanks PS. Does anyone else find that there is now a delay of about a second when you untick "Set date and time automatically"? In previous versions (I think it was 10.8 and earlier) it'd happen instantly.
