Hey guys i have a small problem. There is a time limit on my computer but i can't change it since i don't have admin privileges. I'm on a macbook air running snowleopard 10.6.8. Here are methods i have tried but have been denied by admin: Change password admin with headpassword. Start up in terminal mode. Root. I have seen forums but i just can't find an answer on those so i'm simply asking it again. please help?
