Hi, I recently took over a network with Mac laptops running Mac OS Yosemite, the laptops were part of a Windows Domain had have some administrative lock down settings. We were provided admin privileges so we removed them from the Domain, although we are the computer admins many settings in system preferences are locked out. It seems to me the previous tech support company used some type of lock down policy to prevent even local administrators to make any changes. Unfortunately the previous company won't cooperate passing down info other than providing the admin password.
Does anyone know of a way to "unlock" the settings in system preferences?
