After it restarts, your Mac will guide you through the installation process. Although the guided instructions are usually all you’ll need for a successful installation, we’re going to take a little detour and use Apple’s Disk Utility to make sure that your hard drive is up to snuff before you install your new Leopard OS.
Verify and Repair Your Hard Drive
- Select the main language OS X Leopard should use, and click the right-facing arrow.
- The Welcome window will display, offering to guide you through the installation.
- Select ‘Disk Utility’ from the Utilities menu located at the top of the display.
- When Disk Utility opens, select the hard drive volume you wish to use for the Leopard installation.
- Select the ‘First Aid’ tab.
- Click the ‘Repair Disk’ button. This will start the process of verifying and repairing, if necessary, the selected hard drive volume. If any errors are noted, you should repeat the Repair Disk process until Disk Utility reports ‘The volume (volume name) appears to be OK.’
- Once the verification and repair are complete, select ‘Quit Disk Utility’ from the Disk Utility menu.
- You will be returned to the Welcome window of the Leopard installer.
- Click the ‘Continue’ button to proceed with the installation.
