Sudo dd if="location of Niresh disk image" of=/dev/r"identifier" bs=1m Be sure to download the newest version 6 of Multibeast, not the older versions 3, 4, or 5 (which are for Snow Leopard, Lion, or Mountain Lion respectively).
Also, 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. Be sure to read the Hackintosh compatibility guide very carefully, to check whether or not your computer qualifies. However, not every computer will work with Mac OS X.
If your computer already has Mac OS X installed, Niresh will just update OS X normally, without deleting any of your apps or files. It can be the same computer as the one mentioned in the previous point.
Normally, you can bypass this limitation on Unibeast by applying the MBR patch however, Niresh does this for you automatically, saving you one extra step. Therefore, if your computer's hard drive already has Windows installed on it, you won't be able to install Mac OS X on there.
By default, the Mac OS X installer will not work with hard drives that were originally formatted in Windows.
By default, Niresh will automatically install necessary Hackintosh-specific kexts and drivers for your computer when you boot your Mac OS X installation for the first time. However, with Niresh, you can just set up everything from a Windows computer. This usually means that you either have to find a real Mac, or set up a Mac virtual machine. Unibeast is a Mac app, so you need to have an existing Mac OS X installation for it to work.
However, using a distro to install Mac OS X still offers a far share of advantages: Unlike previous versions of Mac OS X, Apple released OS X Mavericks onto the Mac App Store for free, meaning that the Unibeast method is now 100% free to use.
