You will see three options: erase free space, security options, and erase. Next, click the “Erase” tab located in the center of the disk utility window.

You will see your hard drive listed along the left side of the disk utility window. Disk utility should now be opened and visible on your screen. Click “Utilities” and select “Disk Utility”. You should see a drop down list for “Utilities”. Now, move your mouse cursor towards the top of the screen and the OS X menu bar will appear. Click continue to proceed to the next screen. The first screen you get will say “Welcome to OS X Snow Leopard”. You may have to wait a couple of minutes for OS X to load the disc. As soon as you see the Apple logo with the spinning wheel, you can release the “c” button. This will force the Mac to boot from the disc. As soon as you hear the chime of the computer restarting, immediately hold down the “c” button on your keyboard.

To start the clean install, insert your OS X Snow Leopard disc into your Mac and restart the computer. Some reviewers say that the option was removed to prevent some Mac users from deleting all of their information by accident. This option was available on previous OS X releases such as Tiger and Leopard, but not available on Snow Leopard. You will have noticed that when you insert your Snow Leopard 10.6 disc into your Mac, it does not give you an “erase and install” option. And it turns out that you can clean install Snow Leopard the old fashion way. But, I wanted to do a completely clean install, as I always do with a new operating system.

They told me no you cannot, and I purchased it anyways. I asked an Apple representative if you could clean install Snow Leopard before I even decided to purchase it. However, Snow Leopard can be clean installed. Apple officially released Snow Leopard to be an upgrade only. This would be a great option for OS X Tiger users who are unable to upgrade directly to Snow Leopard.

You can clean install the entire operating system. Many Mac users are not aware that you do not have to upgrade Leopard to Snow Leopard.
