Help! This month I purchased a Oct. 2011 MacBook Pro OS 10.7.4 from a guy on eBay. Seems to work just fine but cannot get all his stuff off the machine. I contacted him and got his password. Then I changed the computer name (under Sharing), and removed him as a user and made myself administrator (Users & Groups). I deleted all his old files that I could find (dragged to trash and did Secure Empty Trash) . However he keeps showing up ...... Today I tried to update Apps at the App Store and his account shows up. When I log him off/out and put in my info I get an error message! ("You have updates available for other accounts. Sign in (to other guys account" to update.") AND it won't let me update my apps from my account. I have no idea where he will pop up again.....
Is there any hope other than doing a COMPLETE scrub of the machine and starting over? There were no discs included.... assume I would have to get OS as download? Also, I have already installed my Microsoft Office suite and to reinstall would lose one activaiton.
