UniBeast is described as 'tool for Hackintoshes that creates a bootable USB drive from your copy of the Install Mac OS X Lion app, Install OS X Mountain Lion app, or OS X Lion USB Thumb Drive. This all-in-one bootable USB drive can also be used as a rescue boot drive for system recovery' and is an app in the OS & Utilities category. There are four alternatives to UniBeast for Mac. The best alternative is xMove, which is free. Other great apps like UniBeast are Kakewalk (Free), myHack (Free) and rBoot (Free).
xMove allows you to install OS X 10.7 Lion on any supported Intel Core 2 or Core i based PC. It moves the required installation files for Lion to a separate partition on your hard drive so that you can install Lion manually.
The sole purpose of Kakewalk is to make it as easy as possible to install OS X Lion or Mountain Lion on your PC. Kakewalk tries to remove all of the painful fiddling and tinkering so that you can be up and running within a few hours.
myHack aids in the installation of a retail copy of OS X 10.6 “Snow Leopard”, OS X 10.7 “Lion”, and OS X 10.8 “Mountain Lion” on a PC. This is commonly referred to as “Building a Hackintosh” or “Hackintoshing”.
rBoot is a boot CD that allows Hackintoshes to boot Mac OS X Lion and Snow Leopard! It will even boot installer partitions created by xMove. Features: - No kernel included - boots both 10.6.x Snow Leopard and 10.7.x Lion installations.
