Preparing the Installer

A Catch-22 of sorts, the simplest way to prepare the OS X Mountain Lion installer for your Hackintosh is by using another Mac. The only way to legally pay for and download Mountain Lion is through the Mac App store, but if you can get the installer files, an installer drive can be created under Windows.

Since we have a Mac on hand, we will be using it to create the bootable install drive for our Hackintosh. The process is relatively easy, so borrowing a friend’s Mac for a few hours (including the download time for Mountain Lion) may worth the effort if you have that option.

After purchasing Mountain Lion from the Mac App Store, a program called Unibeast, available from the tonymacx86 site (registration required) can be used to create an installer drive which we can use to install OS X on our Hackintosh.

First, however, we will have to format our USB drive with the Mac OS Extended (HFS+) file system and make sure it has a Master Boot Record partition table. To do this, we will perform the following steps:

First, open Disk Utility, select your USB Drive, and go to the Partition Tab.

Next, select “1 Partition” from the drop down, and make sure the Format on the right hand side is set to “Mac OS Extended (Journaled).” Under the name field, name this partition “USB” so we can reference it in the future.

Finally, hit the options button, make sure Master Boot Record box is ticked hit OK, and then hit the Apply button in the main window.

Now it's time to open the UniBeast installer that we downloaded and create the boot drive.

Continue the installer until you get to the drive select screen.  Be sure to select the “USB” drive that we just created.

With our hardware setup (or any Socket 1155/2011 desktop) we will leave the additional options provided unchecked, and continue through the installer.

The progress bar may say that this will take several hours but don’t panic, it should only take about 10-20 minutes. Just be sure not to stop or interrupt the installer at this time!
