You can reuse this USB drive for normal stuff after you finish installing Mavericks. Since Unibeast will erase all of the files on your USB drive, make sure to back up its contents first. An empty USB drive (8 GB or larger): The USB drive used for Unibeast must be at least 8 GB in size.

(you might be able to circumvent this requirement by spoofing your system version) (a guide about spoofing the system version will be posted soon). Though the Mac App Store is included in Mac OS X 10.6.6 and newer, you have to be running 10.6.8 to download Mavericks. OS X Mavericks (Free): The method used by this guide requires that you download a free copy of the Mavericks installer app from the Mac App Store. Be sure to install the Virtualbox Extension Pack to view USB drives from your virtual machine. 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.
