What kind of sorcery is this? I know how to add password to log in screen, My macbook ask me before installing anything but how does my school password lock me from downloading chrome and also logging into my calendar through ical? I ask this not to bypass my schools computer but rather I want to be able to add this kind of security to my own mbp. Anyone know how I can add these security features on my macbook pro?
