When you’re ready to upgrade to Leopard (OS X 10.5), you will need to decide what type of installation to perform. OS X 10.5 offers three types of installation: Upgrade, Archive and Install, and Erase and Install. The last option, Erase and Install, is also known as a clean install because it fully erases the selected hard drive volume before installing OS X 10.5.

The advantage of Erase and Install is that you end up with a completely new operating system, without any debris from previous versions. The Erase and Install option should therefore offer the cleanest, smallest, and best performing version of OS X 10.5. It can also be the quickest install, when you are purposely creating a fresh install with no user data to restore. For example, if you’re handing down your computer to other family members, you might not want them to have access to your old information.

Of course, there are downsides to using Erase and Install, particularly if you do intend to restore your user data. Unless you make advance preparations, the erase process will wipe out all of your data. If you want to restore your user data, you’ll need to first create a backup of your existing startup drive, so you can selective reinstall the data you need after you install OS X 10.5.

If you’re ready to perform an Erase and Install of OS X 10.5, then gather up the necessary items and we’ll get started.

What You Need

  • A Mac with a G4, G5, or Intel processor, 512 MB of RAM, a DVD drive, and at least 9 GB of free space.

  • A Mac OS X 10.5 Leopard Install DVD.

  • A half hour to two hours of time. The amount of time the installation will take depends on the type of Mac you’re installing OS X 10.5 on.
