Installing Tiger involved quite a bit of work, and may have taken someone with advanced knowledge of computer software an entire weekend to perfect. Drivers were hard to come by, and it was largely luck of the draw if you were able to get your particular hardware to work with Tiger. Leopard was an evolutionary step forward, automating much of the process and having great compatibility with PC architecture. More modern devices are supported automatically, both through default Leopard software, and from the lovely folks who compiled these hacks in order to liberate OSX for the masses.

This was mostly accomplished because Leopard was meant from the beginning to be used on computers with the x86 Intel architecture. The roadblock keeping OS X from naturally running on any pc is something called EFI, or Extensible Firmware Interface. The EFI that Leopard uses is only tooled to work with Apple hardware, which means that it needs to be patched. The original method of patching was to use a thumbdrive attached to the computer and utilize the terminal to transfer files from the thumbdrive to the operating system files of Leopard. Compared to installing Tiger onto a PC, this method was ridiculously easy and was all that was required to have a successful boot of Leopard. But a better solution is now available, one where no thumbdrive is required and installation is streamlined and so easy that nearly anyone can do it.

This is a set of guidelines for installing OS X Leopard onto a PC. What you choose to do with this information is up to you, and I am in no way responsible for whatever happens to your machine.

The things you need for this project are as follows:
• High Speed Internet Connection (Useful if you want the disk image before the end of time)
• Blank DVD-R (or two, I'll get to that later)
• Nero, or some other program that allows the burning of disk images to blank media
• A BitTorrent program such as BitComet or Transmission
• A computer with the following attributes:
o Processor with either SSE2, SSE3, or SSE2/3 capabilities.
o at least 512 MB RAM
o at least 9 GB of free disk space
o A DVD drive for installation

Preparations:

In order to install Leopard, you first need to get the Leopard OSX86 installation disk. Now, the legality of this is somewhat questionable. The general consensus is that there are three ways to go about this, and I will order them in the most painful to least painful:
• Become an Apple developer. After several years or decades of convincing Apple Corp. that it would be a great idea to open up their kick ass operating system to the public for use on PC's, you can probably install the now defunct and outdated leopard onto your PC free of legal worries.
• Buy a Leopard License, and then go and download Leopard from Apple site etc. So that way at least your giving your money for a Leopard license and choosing to use it on a computer. Even though the license agreement specifically states that you cannot use OS X on anything but apple hardware. Oh well, it happens.
• Who cares, just download it. This is the most common method, and also the least legal.

Then you need to burn the .iso file to the blank DVD. I prefer using Nero to do the burning, but you may have another program that does a similar job.

If you’ve never booted from a CD or DVD on your system, then follow the outlined steps. If you already know how then just skip the next paragraph.

Insert the dvd into your dvd drive and shutdown the computer. Then whenever the computer boots up, pay attention to if it says anything about boot sequence or BIOS setup in the first few seconds of booting. For most Dell systems that I’ve come across the Boot Sequence option can be reached by hitting F12/F2 at startup(intel/other). For HP it is usually F2. Other BIOS’s might be Del or any of the F keys. Then select your CD/DVD drive, and the computer will boot from it after hitting enter.

Here is what a Dell Dimension 3000 BIOS boot selection screen looks like:
(The CD/DVD drive is highlighted)

let the DVD boot up, it will eventually say something like "Press any key to begin or F8 for options . . ." (I know it isn't exactly that, but it is similar), if you press any key the next screen pops up:
