Hi! How can I restore a iMac 10.6.5 Snow leopard to factory settings?


iMac, Mac OS X (10.6.5), MB-952XX/A

    If your goal is to stay on 10.6.x, then you will need the original installation media.  Back in the 10.6 days, machines still shipped with installation DVDs (gasp).  You can boot from the original install DVD, erase or repartition the drive, and then reinstall the OS.

     

    If you are looking to upgrade (and this unit is Mavericks compatible), you can upgrade to Mavericks.  Assuming the drive is not partitioned, this will create a Recovery Partition.  If you truly want to nuke and pave, boot from the Recovery Partition, erase the boot partition, and then reinstall Mavericks.

     

    Either will get you a clean system.

    Thanks for responding to my question.

     

    I failed to mention that this was my sister's iMac.

    She does not remember the Password or Apple ID #,

    and there aren't any disks that came with it.

     

    Thanks,

    Steve

    You will absolutely require a disc, preferably its original OS X Install DVD, but you should also be able to use the retail Snow Leopard DVD since yours is a late 2009 iMac. Purchase it here: http://store.apple.com/us/product/MC573/mac-os-x-106-snow-leopard

     

    You can obtain a replacement OS X Install DVD from Apple at a reasonable cost, about the same as the Snow Leopard DVD. Contact them using the phone number that appears in the Apple Online Store. You will need the iMac's serial number: iMac: How to find the serial number

     

    Once you have it follow the instructions in CMCSK's link.

    You can reset the password via Single User Mode or you can completely remove the dslocal database and start over.

     

    If you want to delete the DB and start over (no user data will be deleted), follow these steps:

     

    1:  Boot the machine into Single User Mode (Hold down Command and S keys on boot up)

    2:  When you get to the command prompt, mount the file system as writable with this command:

     

         mount -uw /

     

    3:  Deleting the old Default node...

     

         rm -R /var/db/dslocal/nodes/Default

     

    4:   Copying Default node template...

     

         cp -R /System/Library/DirectoryServices/DefaultLocalDB/Default /var/db/dslocal/nodes/

     

    5:  Removing Shadow Hash files... (depends on history of machine)

     

         rm -R /var/db/shadow/hash/

     

    6:  Removing .AppleSetupDone...


         rm /var/db/.AppleSetupDone


    7:  Reboot the machine with the reboot command


    That will present you with the setup assistance and no users on the machine.  Create a new account on the machine.
