How to Turn Your Computer Into a Leopard OS X
- 1). Back up all of your current data and your operating system on an external hard drive. Turning your computer into a Leopard machine requires that you reformat the drive, so all of your data will be lost in the process. The backup also ensures that you'll be able to reset your machine if you're not happy with OS X.
- 2). Buy a copy of the Leopard OS X install DVD. If you have a copy of the operating system for one of your other computers, you can use that disc again as long as you purchased multiple licenses for the software.
- 3). Find and download the appropriate OS X patch for your computer's processor. For example, if you have an AMD processor, you need the AMD OS X Leopard patch. Insert a USB drive, right-click on it, format it to FAT32 or FAT16 and rename it "Patcher." Copy the uncompressed OS X Leopard patch onto the USB drive.
- 4). Insert the Mac OS X install disc and shut down your computer. Connect the USB drive that contains your OS X Leopard patch. Turn on the computer and press "F12" while it's launching. Choose the "Boot from Disc" option to launch from the install DVD.
- 5). Wait for the OS X install window to appear and choose your language. Select "Custom Install" and deselect all of the extensions and applications. This installs only the essential elements of Leopard OS X to minimize any software or hardware conflicts.
- 6). Restart your computer after the installation finishes and press "F12" to boot from the install DVD again. Ignore the error message that says you have already installed Leopard, close the installer and select "Terminal" from the "File" menu. Enter the following commands: "cd ..", "cd ..", "cd Volumes", "cd Patcher" and "cd files". Type "./9a581PostPatch.sh" into the terminal to run the OS X patch from your USB memory stick. Restart your computer.
