I want to give my emac to a friend for helping me. I need to wipe the hard drive first of all personal information. I do not know how to do that, any help would be appreciated. Thanks.

iMac, Mac OS X (10.5.8)

    Prepare Your Mac for Sale

     

    Boot from the OS X Installer Disc One that came with the computer.  After the installer loads select your language and click on the Continue button.  When the menu bar appears select Disk Utility from the Utilities menu.  After DU loads select the startup volume from the left side list then click on the Erase tab.  Set the format type to Mac OS Extended (Journaled) then click on the Options button.  Select the one pass Zero Data option and click on the OK button.  Then click on the Erase button.

     

    Note: You can skip the Zero Data option if you are not concerned about removing sensitive personal data from the hard drive.  If you choose to skip this part of the process then it is possible for others to recover data from the hard drive.  The Zero Data procedure will prevent others from getting access to your personal information.

     

    This process will take 30 minutes to several hours depending upon the size of the hard drive.  After formatting has completed quit DU and return to the installer.  Now complete the OS X installation.  At the completion of the installation do not restart the computer.  Instead just shut it off.  The next user will be presented with the Setup Assistant when they turn on the computer just as it would if new out of the box.

    Could a person simply just create a new admin user account and delete the previous admin account from the new one? That would be much simpler... especially for an emac.

    Yes, you can do that as long as you have no need to preserve anything in the other account. However, if you are concerned about sensitive information on the computer then be sure when you erase the old account that you use Secure Erase of the account or use Secure Erase Free Space afterwards.

     

    Of course this is not a recommended method. And, you need system install discs to go with the computer when it's disposed.
