The machine came with 10.5, those disks are not available anymore from Apple.
You use the $29 10.6.3 white retail disks you get from Apple store online or already have in your possession.
Yes you upgraded OS X 10.5 to 10.6.3 with them, it also contains the entire 10.6.3.
When you "upgraded" your Applications and User accounts folders remained while only OS X 10.5 folders was replaced with 10.6.3 folders.
So if you hold the c or option key down while booting from the 10.6.3 disks, you can use Disk Utility to erase the entire drive and reinstall 10.6.3 only, like a brand new machine.

  • HT204406 How can I reset iTunes Match to my original version, before it was corrupted by iMatch?

    How can I reset iTunes Match to my original version, before it was corrupted by iTunes Match? I have a extensive library I developed over years and it has been totally destroyed by iTunes Match and I have not been able to rectify it, no matter what.

    Hallo Jim, thanks for the response.
    I have a library of around 9000 songs, about 40 playlists and all albums sorted etc. It was originally kept on a Windows 7 based system. After linking the entire library on iTunes Matc (which took forever), all was fine for a while, then suddenly double playlists start apearing, songs disapeard form playlists and I started to loose all my settings!
    In a last attempt to solve my problems, I purchased a Mac to use at home with all the other Apple devices. (Appletv, iPads etc) Unfortunatelly despite numerous attempts I have not been able to copy the library over to the MAC, as I keep on loosing half of the data. I tried iTunes Match, but this made things even worse.
    Reading several forums and tutorials and trying everything, simply helped me to recover an older version of the Library by copieng a pervious version and replacing the current .itl file. (on the Windows based system)
    So, I now have a fairly updated and complete iTunes Library on my Windows based computer at work, but all my other devices and MAC at home have skeleton versions of the original Library.
    I have disabled iTune Match on all sytems as well as Genius , as this seams to be escalating the problems by creating multiple versions of my existing playlists, but none that are complete.
    If you have advice for me, or can refer me to a detailed and accurate tutorial, I will be very grateful.
    Thank you,
    Hennie

  • HT4623 iPhone 4s will not boot after trying to install ios7 beta 4. Stops at apple logo with progress line under it. how can I reset it or get it back up to do a restore then try the iOS 7 beta 4 install again. Issue was probably caused by disconnection

    iPhone 4s will not boot after trying to install ios7 beta 4. Stops at apple logo with progress line under it. how can I reset it or get it back up to do a restore then try the iOS 7 beta 4 install again. Issue was probably caused by disconnection

    Obviously since you have iOS 7 you're a developer.  As a developer, you signed a NDA with Apple not to discuss the iOS on a public forum.  Please log in to the Developer Forum using your credentials and ask for help there, lest you risk having your credentials terminated.
    Thanks, and best of luck to you.

  • Grandaughter has locked i pad 2 with passcode and then forgotten number how do you reset i pad to get it to work again

    grandaughter has locked i pad 2 with passcode and then forgotten number how do you reset i pad to get it to work again

    If You Are Locked Out Or Have Forgotten Your Passcode or Just Need to Restore Your Device
      1. iTunes 10 for Mac- Update and restore software on iPod, iPhone, or iPad
      2. iPhone, iPad, iPod touch: Wrong passcode results in red disabled screen
      3. iOS- Understanding passcodes
         If you have forgotten your Restrictions code, then follow the instructions
         below but DO NOT restore any previous backup. If you do then you will
         simply be restoring the old Restrictions code you have forgotten. This
         same warning applies if you need to restore a clean system.
    A Complete Guide to Restore or Recover Your iDevice (if You Forget Your Passcode)
    If you need to restore your device or ff you cannot remember the passcode, then you will need to restore your device using the computer with which you last synced it. This allows you to reset your passcode and re-sync the data from the device (or restore from a backup). If you restore on a different computer that was never synced with the device, you will be able to unlock the device for use and remove the passcode, but your data will not be present. Refer to Updating and restoring iPhone, iPad and iPod touch software.
    Try restoring the iOS device if backing up and erasing all content and settings doesn't resolve the issue. Using iTunes to restore iOS devices is part of standard isolation troubleshooting. Restoring your device will delete all data and content, including songs, videos, contacts, photos, and calendar information, and will restore all settings to their factory condition.
    Before restoring your iOS device, Apple recommends that you either sync with iTunes to transfer any purchases you have made, or back up new data (data acquired after your last sync). If you have movie rentals on the device, see iTunes Store movie rental usage rights in the United States before restoring.
    Follow these steps to restore your device:
         1. Verify that you are using the latest version of iTunes before attempting to update.
         2. Connect your device to your computer.
         3. Select your iPhone, iPad, or iPod touch when it appears in iTunes under Devices.
         4. Select the Summary tab.
         5. Select the Restore option.
         6. When prompted to back up your settings before restoring, select the Back Up
             option (see in the image below). If you have just backed up the device, it is not
             necessary to create another.
         7. Select the Restore option when iTunes prompts you (as long as you've backed up,
             you should not have to worry about restoring your iOS device).
         8. When the restore process has completed, the device restarts and displays the Apple
             logo while starting up:
               After a restore, the iOS device displays the "Connect to iTunes" screen. For updating
              to iOS 5 or later, follow the steps in the iOS Setup Assistant. For earlier versions of
              iOS, keep your device connected until the "Connect to iTunes" screen goes away or
              you see "iPhone is activated."
         9. The final step is to restore your device from a previous backup. If you do not have a
              backup to restore, then restore as New.
    If you are restoring to fix a forgotten Restrictions Code or as a New device, then skip Step 9 and restore as New.

    You don't. If you cannot locate the original owner, then the device is useless to you. If you purchased it from someone, try returning it for a refund, otherwise it is an expensive paperweight.  Find My iPhone Activation Lock - Apple Support

  • HT201304 how do you reset the restriction password on an ipod touch

    How do you reset a forgotten restriction password on an ipod touch

    They will be erased from the iPod along with everything else, but since those songs must have originated from a source other than the iPod, they must still exist on the computer you used to sync it.
    After you restore the iPod, you just have to sync it with that same computer again.
