Install MAC OS X Mountain Lion on Windows PC

Install MAC OS X Mountain Lion on Windows PC. Installing MAC OS X on Windows PC is become a lot easier than it was  couple of year ago, when I first installed Mac OS Leopard 4 years ago on my home PC it required many different commands before starting the installation and even after installation I had to crack the kernel of various hardwares to make them work(e.g. Graphics card, sound card etc). Without going into many details let’s check the compatible desktops and laptops which are already in the market.

Compatible Portables:

Compatible Laptops/Desktops/PCs:

If you have a system with different configuration than the above given compatible systems then you need not worry, you can still try to install Mac on your pc computer.

In order to start fresh, you’ll need access to a functional computer running Mac OS X Snow Leopard 10.6.6 or later. This is a requirement, as you need OS X to create the installation drive.

Things we need

1)      8GB USB Drive

2)      A copy of mac OS Mountain Lion(Purchase it from app store or download its torrent from

3)      Unibeast (helps to create bootable mac  osx usb drive, get this tool from

4)      Multibeast


STEP 1: Create a Bootable USB Drive Using UniBeast
Take a deep breath and take your time- this is pretty simple, but it’s easy to miss things if you rush. Follow each step to the letter.

1. Insert the USB drive
2. Open /Applications/Utilities/Disk Utility
3. Highlight the USB drive in left column

4. Click on the Partition tab
5. Click Current and choose 1 Partition

The process will only take about 10-15 minutes, depending on system and drive speed, but will show hours. This is normal. Do not unplug or stop during this time.

STEP 2: Install OS X Mountain Lion

you’re almost done! All you need to do is boot from the USB drive and install! Set your BIOS or UEFI to Optimized Defaults, and your hard drive to AHCI mode.

1. Turn on the computer
2. Press the hotkey to choose boot device

  • If you have a Gigabyte motherboard press F12
  • If you have a ASUS motherboard, press F8

3. Choose USB-HDD

4. At the Chimera Boot Screen, choose USB and hit Enter

Optional Boot Arguments & Troubleshooting Tips
For some hardware, it may be more difficult to get to the installation screen. You may have to type extra boot arguments in the system at the boot screen you see above. You can hit arrow-down as well on the boot screen to access boot options. Here are a list of things you can try in order to troubleshoot booting to the installer. You will have to troubleshoot this part yourself according to your own hardware specs. We’ve provided a few tips below.

Black Screen, White Screen, Flickering Screen

It’s your graphics or possibly your choice of graphics port. The DVI or the HDMI port are usually the most compatible for installation. Reboot and try another port or one of the following flags.

UniBeast has PCIRootUID=1 set by default for the most universal support for recommended builds. Set it manually to 0 by typing this command at the boot screen above. For example, use this setting on UEFI motherboards with NVIDIA cards.

You can install without graphics card injection. This can solve many issues, allowing you to access the installer screen. For example, use this setting on NVIDIA 6xx Cards.
Verbose Mode- allowing you to see the loading of the OS instead of the Apple Boot Screen.
Safe Mode- loads only basic drivers. Sometimes a cure-all to reach the installer.

Special Instructions for AMD 6xxx Graphics Cards: 
There is an issue with AMD 6xxx cards in Mountain Lion. We recommend using an alternate graphics card or onboard Intel HD 3000/4000 graphics for the entire process. After you’re fully installed, you can switch back to your 6xxx card.

5. When you arrive at the Installer, choose language.
6. For a new installation of OS X, you MUST format the destination drive according to the following steps before continuing.

NOTE: If you are upgrading from Snow Leopard or Lion and you want to keep your files and apps, you can skip steps a-j.

a. In the top menu bar choose Utilities, and open Disk Utility
b. Highlight your target hard drive for the Mountain Lion installation in left column.
c. Click Partition tab
d. Click Current and choose 1 Partition
e. Click Options…
f. Choose GUID Partition Method
g. Under Name: type Mountain Lion (You can rename it later)
h. Under Format: choose Mac OS Extended (Journaled)
i. Click Apply then Partition
j. Close Disk Utility

7. When the installer asks you where to install, choose Mountain Lion, or your existing install.

8. Upon completion, restart the system.

STEP 3: Post-Installation Using MultiBeast

MultiBeast is an all-in-one post-installation tool designed to enable boot from hard drive, and install support for Audio, Network, and Graphics. In addition it includes System Utilities to repair permissions and a collection of drivers and config files. The installation is complete, but the drive isn’t bootable yet. Boot from the USB again, this time choosing Mountain Lion.

1. Turn on the computer
2. Press the hotkey to choose boot device
