So my father got a new Macbook and I was trying to transfer over some of my files. I turned on file sharing (on my own computer, MBP) and accidentally removed myself from the permissions list for the Applications folder. Stupid, I know. Now I can't access anything: Any application, System Pref., Time Machine, etc....... Applecare's solution is to reinstall Leopard, not sure where the hell the disk is now. But I know I still have it. Is this the only course of action? Would repairing my permissions solve it? (using the install disk to access it) Thanks!!!!
