Alternatively, you could install Mountain Lion on a virtual machine (which I will post soon), and run Unibeast on there instead. You could use a real Mac, if you own one. A Hackintosh with Snow Leopard/Lion/Mountain Lion 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.

Unibeast works with Mac OS X Snow Leopard and newer registration on is required to download Unibeast. You can then use this Unibeast USB drive to run the Mavericks installer on a PC. Unibeast (Free): Unibeast is a Mac program that modifies the official OS X Mavericks installer, and writes it onto a USB drive. You can bypass this requirement by applying the MBR patch to Unibeast (which I will post soon) (the process for Mavericks is the exact same as for Mountain Lion). Unibeast will not work on a hard drive where Windows was installed first. A separate hard drive: Mac OS X needs its own hard drive (a minimum of 10 GB of space is required, but at least 50 GB of space is recommended).

If your computer already has OS X Mountain Lion installed, Unibeast will just update Mountain Lion to Mavericks normally, without deleting any of your apps or files.

The hardware requirements for OS X Mavericks are identical to those for OS X Mountain Lion AMD processors and older 32-bit Intel processors (such as Pentium M) are not supported. Be sure to read the Hackintosh compatibility guide (which I will post soon) 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.
