I need to reset the admin account and password on a used 27" imac I purchased running OS 10.7  Can anyone help?

    If it's running Lion, it'll have a Recovery Partition. Reboot the Mac while holding down cmd-R - keep both keys held until it boots. Ignore the on-screen options, go to the Utilities menu, then Terminal. Type:




    and change the admin password. I'd also advise you, once you have the password correct, to create a brand new admin account, log in as that account and delete the old one.

    Did the iMac have Lion preinstalled originally or did it originally come with a different OS and install disks?
