INSTALL MAC OS LEOPARD ON ORDINARY PC

Make sure you backup all important data before you proceed. Here are the things that you will need before Install Leopard on your PC.

*The Patched DVD Image
*The zip file containing the patch
*One pen drive or USB Flash Drive formatted as FAT32

Well once you have all these you can go ahead and Install Leopard.


Step 1. Getting things ready
Burn the DVD Image onto a Single Layer DVD-R using a software like Nero.
Format the USB Flash Drive and the drive label should be “Patcher” without the quotes. Please note it has to be “Patcher” only and nothing else for the patch to work when we apply it later.
Extract the Zip file and put its contents into the USB Flash Drive.
Now your USB Drive should contain a folder called “files”, if it doesn’t then check to see where you have gone wrong.


Step 2. Installing Leopard
Now that you have the Patched DVD with you, you can now install Leopard. Pop in the DVD into the drive and boot into it by pressing F12 at the BIOS Prompt.
Boot into the DVD and the installer should now load. It take a while though, so be patient.
Select your Language and make sure you select Customize and you need to deselect all the packages that are displayed.
Leopard will now install. This can take a while, so go grab yourself a coffee.
It will ask you to Reboot, so go ahead and Reboot. Before rebooting make sure that USB Flash Drive is connected to the PC.


Step 3. Patching Leopard
Now that you have got Leopard installed, you need to patch it. Before we do that Boot into the Leopard DVD like the way you did before.
Wait for the Darwin Bootloader to load. Once it loads up press F8. You should now see a prompt. Type -s and hit enter. The DVD will now load in Verbose mode. Watch for any errors. It should load without a problem because you have already installed Leopard.
Once the setup is loaded select your Language. Once done you should now be seeing the Welcome Screen. Once there navigate to Utilities-Terminal.
Once the terminal loads up, you now need to browse to your USB Drive, so follow the steps below, typing it exactly as it appears below in the Terminal.


In the command line type the following as they appear here:

cd ..
cd ..
cd Volumes
cd Patcher
cd files

Notice the space between cd and the 2 dots.
Now its the time to run the patcher to make sure Leopard will work on your PC. Type the following into the Terminal.


./9a581PostPatch.sh
The Patch should now run. You can answer Yes while removing the ACPUPowerManagement.kext
After the Script is done, you should now be able to Boot into Leopard after you restart.


Step 4.
Well that was it. Please note this has not been extensively tested, so most of your Hardware like Sound, Network may not work. If something goes wrong for you or you want to help us, then please join the discussion over at OSX86Scene. If you noticed I haven’t posted the links to the Torrent that contains the DVD image and the zip. Well I haven’t posted them because I am sure the lawyers over at Apple are going to sue the hell out of me. If you wondering where you can find them, then head over to Demonoid and search for it.

Well here are few screenshots by Mac.nub over at the forums who could get Leopard working on his system.
