I reformated my Powerbook to factory using the Installation disks that came with my computer.


Accidently I needed to create a users to log in and get the necessary serial number, cpu, ram etc to list for resale.


I then reformed the computer again and the user I created remains the admin of the computer. ( I have tried re-installing twice)


I need to get this back to factory settings and welcome a new users to sign in and take ownership of the computer.


How can I restore back to the factory settings for the new owner to create their profile?



PowerBook G4 (15-inch 1.67/1.5 GHz), Mac OS X (10.4)

    Erase it again & reinstall, shut it down when complete, or when the Welcome screen appears after it restarts, the new owner will be greeted by the Welcome to OSX on startup.

    Thank you for your response. I am reinstalling using the instal disks and after it is completed it simply logs in as the user I created before.


    Will not prompt a new welcome/startup.


    I dont understand how it is maintaing the profile. How can I more thouroughly erase for the remfort?

    Hmmm, did you use Disk Utility to reformat the drive before the reinstall?

    Is it possible to reformat the drive while using the computer? I tried and couldnt find a way to reformat while in use. It only has a single HD.


    Thanks for the help!

    Not while booted from the Hard Drive, only the Install Disc...


      1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.

       2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu at the top of the screen. (In Mac OS X 10.4 or later, you must select your language first.)

         *Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*

       3. Click the Erase tab.

       4. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.

       5. Select your Mac OS X volume.

       6. Highlight the drive, select Partition Tab, then Format type... MacOS Extended Journalled, select the Security Options button, choose Zero Out Data, Erase, one pass... after completion hopefully you'll be able to get a good install.
