I'm helping a friend with an estate sale. The computer is a Mac Mini G4 that's still running OSX 10.4.11. My question pertains to the security of the account registered on the device. The original owner of the computer is now deceased but their account is still active on the machine. I would love to just erase his account but I'm not sure how or if that would render the machine unusable. I don't have the original Tiger install disc either. If I sell the machine with his account active (it goes right to his desktop with no password, which I don't have anyway), am I taking any security risk? I have already erased any private information from the hard drive but coming from an iPhone/iCloud background, I am unsure if anything could be restored from the cloud or not. Thanks for any help.
