How to easily use your Leopard Upgrade DVD as a Full-Install Disk

If you have purchased your Mac after 1st October 2007 and before the official release of Leopard on 29th October 2007, you are eligible to receive a Leopard upgrade DVD. You would have received an upgrade DVD as a drop-in disk in your package if you have been given a Tiger-equipped machine from their inventory. If you have an upgrade DVD, you will not be able do a clean install of Leopard. This means that if your disk or installation gets corrupted, you will have to install Tiger first before upgrading to Leopard using the DVD. You can save the trouble by converting your DVD to a full-install disk with the following steps:

  1. Start your Mac with the Leopard Upgrade DVD in the optical drive and hold the ‘C’ key to boot from the DVD.
  2. After the installer initialises, it will perform a check to confirm that you already have an existing install of Tiger or Leopard.
  3. At this point, if you do not have a functional version of Leopard or Tiger, the installer will not let you proceed.
  4. Here are the workaround steps: Click on “Utilities” then on “Restore Time Machine Backups”.
  5. Click “Next” and the installer will start searching for Time Machine backups.
  6. Wait for about 5 Seconds then go all the way back to the Mac OS X Installer.
  7. Now the continue button should be clickable and you can proceed to do a clean install of Leopard.
  • This method will work even if you do not have a Time Machine backup. You just have to click “Next” then go back to the “Restore from Time Machine” option.
  • This workaround has been tested on both 10.5.0 and 10.5.1 DVDs.
