I purched a used macbook from a yard sale. this was suppossed to be an exwifes computer that he didnt know the passwords to. So i figured that I would just buy the restore disc and reset every thing including passwords. well when I put the disc in instead of any thing prompting me to reload. A lock with a place for a password pops up. can I get around this. I think this might be an old school computer with the extra protection so you cant reboot the computer. Is there any way I can reboot this?
