As one last option, y ou could install Snow Leopard on a virtual machine, and run Unibeast on there instead. Alternatively, you could install Mac OS X Snow Leopard on your PC, and then follow this guide to update your PC to Lion (if your computer uses an Ivy Bridge processor, be sure to use iBoot for Ivy Bridge). You could use a real Mac, if you own one.

A Hackintosh with Snow Leopard already installed, a real Mac, or a Mac OS X virtual machine: Unibeast is a Mac app, so you need a computer with Mac OS X to run it.

You can then use this Unibeast USB drive to run the Mac OS X Lion installer on a PC. Unibeast works with Mac OS X Snow Leopard and newer registration on is required to download Unibeast. Unibeast (Free): Unibeast is a Mac program that modifies the official Mac OS X Lion installer, and writes it onto a USB drive.Additionally, AMD processors do not work with Lion because there is no legacy kernel. Lion is a 64-bit operating system, meaning that old 32-bit processors like Intel Pentium no longer work. Mac OS X Lion has several new hardware requirements, compared to Snow Leopard. Be sure to read the Hackintosh compatibility guide very carefully, to check whether or not your computer qualifies. A compatible computer: Not every computer will work with Mac OS X, even with the help of tools like Unibeast and Multibeast.This guide follows tonymacx86's method, but it also attempts to explain every part of the process in detail, from start to finish (with pictures, thanks to Virtualbox). While tonymacx86's guide on installing Lion is very good, it's also very basic, just like his Snow Leopard guide. We've already covered installing Mac OS X 10.6 (Snow Leopard), but unlike Snow Leopard, Lion doesn't include an installation DVD, which complicates matters. If you're interested in running Mac OS X, but you don't want to pay ridiculous prices for a normal Mac, then a Hackintosh just might be for you.
