Install Mountain Lion Virtualbox

You need a computer with Windows to run Mac OS X on Windows (of course). The “System Type” of your copy of Windows needs to be 64-bit, because OS X Mountain Lion is a 64-bit operating system. If you have a 32-bit copy of Windows, you can only install Mac OS X Snow Leopard on Virtualbox. You will need at least 4 GB of RAM and a dual-core (two core) processor or better. Personally, the computer I was using for this had a 4-core processor and 12 GB RAM, which is way more than enough. You also need about 10 GB of unused hard drive space.
Right click on “My Computer” on your desktop and click “Properties” to check the stats on your computer. If it doesn’t directly tell you how many cores your processor has, look up your processor model on Wikipedia or Google. You also want to find out whether your processor is made by “Intel” or “AMD”. Computers with AMD processors will not work with Mountain Lion.
General Requirements
  • Virtualbox : This virtualization suite is free, and though it doesn’t offer official support for Mac OS X, it works well enough.
  • iAtkos ML2: Unfortunately, the standard method for installing OS X Mountain Lion on PCs (which uses a paid copy of the Mountain Lion installer) doesn’t work with Virtualbox. Instead, you’ll have to distros like iAtkos, which is currently the most popular distro for Mountain Lion. I won’t go into details, but you can download these copies from about any bittorrent website by using a bittorrent client (it’s a “.dmg” file that’s about 5 GB in size).
  • Multibeast 4.6.1: You will need to use Multibeast 4.6.1, our favorite Hackintosh post-installation tool, to set up the Mountain Lion virtual machine after the initial installation. While Multibeast 4.6.1 is an old version designed for Mac OS X Lion instead of Mountain Lion, in our case, it actually works better than newer versions of Multibeast. Registration is required on the tonymacx86 website to download this.
Download Virtualbox, install it, and open it up. Also, if you want to be able to view USB devices from your OS X Mountain Lion virtual machine, download the Virtualbox Extension Pack and run it before going to Step 2.
Step 2: Create a new virtual machine.

Os X Mountain Lion Virtualbox

Virtualbox lets you run Mac OSX within Windows by creating a virtual machine, which is a program that simulates a normal computer. To create a virtual machine, open up Virtualbox and click “New” on the upper left. Give your new virtual machine a name, and choose “Mac OS X” for the OS Type.

If your version of Virtualbox asks you to choose between 64-bit and 32-bit, be sure to choose 64-bit. Choosing 32-bit will result in a critical “Guru Meditation” error later on.

I recommend assigning 4 GB of RAM to the virtual machine, but you can assign as little as 2 GB of RAM. Every time you turn on Mac OS X, that RAM that you assign here will be used to run the virtual machine. The RAM will be given back to your normal computer after you turn Virtualbox off.
You’ll need to create a new hard disk for the virtual machine. Virtualbox will ask you what type of disk you want to create: VDI, VDMK, or VHD. VDI is the original format for Virtualbox, while VDMK is the format used by VMWare. If you’re considering getting a copy of VMWare, you might want to choose VDMK. Otherwise, just choose VDI. I recommend creating a dynamically expanding disk; the only other option, fixed-size storage, will eat up your hard drive.
Step 3: Give your new virtual machine an operating system.
Your virtual machine will now be created. But don’t stop now–you still need to change a few settings before your machine will actually work. Your new virtual machine will show up on the left column of the Virtualbox start page. Select your Mac OS X virtual machine (single-click) from the main page of Virtualbox, and open up the virtual machine settings. Once the settings open up, go to “System” and uncheck the “Enable EFI” box. This is by far the most important single setting that you will need to change.
EFI, which stands for Extended Firmware Interface, is a feature that helps operating systems start up. Unfortunately, Mac OSX requires ‘speshul’ EFI, so the EFI that Virtualbox uses doesn’t work.
Once you’re done with that, go to the settings for “Storage”. In the storage tree box, you’ll see a CD icon labeled “Empty”. Click on it and click “Choose a virtual CD/DVD disk file”. In the window that pops up, choose the .dmg file for iAtkos ML2.

This way, when your virtual machine starts for the first time, it will boot into iAtkos.

Step 4: Install OS X Mountain Lion
Start up your virtual machine. You will come up to the iAtkos boot screen, with a CD icon in the middle.

After a few seconds, the virtual machine will automatically start the Mac OS X installer. (This startup process may take a few minutes.) Eventually, you will reach the welcome page of the installer.

Continue, and you will come up to a page that asks you for a “destination” for your Mac install. Oh no, the page is blank! We’ll have to fix that. To do this, start up Disk Utility (located under the Utilities menu).

Mac OSX can only be installed on a completely clean disk, so you need to use Disk Utility to wipe your Virtualbox hard disk. Click on the Virtualbox hard disk in Disk Utility and erase it. Don’t worry, there’s nothing important on it.

On the installation summary page for Mac OSX, the Virtualbox hard disk should now be showing up. Click the “Customize” button on the lower left-hand corner of the summary page. This is where using a distro becomes really useful: iAtkos allows you to install extra Hackintosh drivers and kexts, straight from the Mac OS X Lion installer. The “Customize” page essentially does the same thing as Multibeast, though the layout (and most of the names of the options) are different.

The default selection will enable Mac OS X to boot from the virtual machine without any assistance. In addition to this selection, go to Bootloader Options -> Graphics Mode and choose whatever resolution best fits your monitor (in my case, I chose “1920×1080”). Selecting this won’t actually change anything at the moment; however, you will need this for Step 7, when we make the screen of the virtual machine bigger.

Once you have selected the appropriate options from the “Customize” screen, return to the installation summary page and click “Install”. When the installation finishes, Mac OS X will crash into a black screen with white text. This is normal; Mac OS X has installed successfully. Now proceed to the next step.

Step 5: Boot it up

Restart your virtual machine, and eject iAtkos from your virtual DVD drive. To eject iAtkos, right-click on the CD icon at the bottom right of the Virtualbox window, and un-check the iAtkos file. Your mouse cursor will probably be trapped inside the virtual machine. Press the right “Ctrl” key on your keyboard to allow your mouse to escape.

After ejecting iAtkos, restart your virtual machine again. Now, at the bootup screen, you’ll see an icon for the hard drive where you installed Mountain Lion (also, the screen of your virtual machine might be bigger than before).

After a few seconds, Mountain Lion will boot, and you should eventually be led to the Mac OS X setup screen. Fill it out, then mission accomplished!

This concludes the first part of the guide. However, you’re not done yet! You still have to enable sound on your virtual machine, and increase the screen resolution.

Step 6: Enable sound

Mountain Lion Virtualbox

By default, your ethernet (internet) should work in the virtual machine. However, the virtual machine will not have sound, or be able to boot from the hard drive without help. To fix this, open Safari, and download Multibeast 4.6.1. While Multibeast 4.6.1 is an old version designed for Mac OS X Lion instead of Mountain Lion, in our case, it actually works better than newer versions of Multibeast. Registration is required on the tonymacx86 website to download this.

DOWNLOAD: Multibeast 4.6.1

Before starting Multibeast, you have to go the “Security” section of System Preferences in Mac OS X, go to the “General” section, and check “Anywhere” in the “Allow applications” section. Once that’s done, run Multibeast and install the following options.

That’s all there is to it; restart your virtual machine. Mac OS X will now be able to play audio normally. Congratulations!

Step 7: Make the screen bigger

Though this step is optional, I still recommend you do it anyways. Anyways, when you first use your virtual machine, you’ll probably notice one thing: your screen resolution is 1024×768. Since Virtualbox doesn’t “technically” support Mac OS X, there’s no official way to change this. But here’s how you can change it anyways.

First, turn off your virtual machine. Open the Command Prompt in Windows (make sure you are logged into an Administrator account on Windows). You can do this by opening the Start Menu, and typing “command prompt” into the Start Menu search bar. Then, type the following command into the Command Prompt.

cd “C:Program FilesOracleVirtualbox”

This command will change the focus of the Command Prompt to the program folder for Virtualbox (if you installed Virtualbox somewhere different, then change the command to wherever you installed it). Next, type in this command:

vboxmanage setextradata “Name of virtual machine” “CustomVideoMode1” “1920x1080x32”

This command activates “vboxmanage”, a command-line program included with Virtualbox that allows you to edit the properties of your virtual machine, including its built-in resolutions. Replace “Name of virtual machine” with the name of your virtual machine– you can find the name of your virtual machine in the left pane of the Virtualbox main window (in the screenshot below, my virtual machine is named “Mountain Mac 2”). Replace “1920x1080x32” with whatever resolution you’re using.

Press the enter key to submit the command. Once that’s done, start your virtual machine again.

Your virtual machine will now boot Mountain Lion in full resolution. Congrats!


I’ll just repeat what I said in my other two Virtualbox guides. Installing Mac OS X on a virtual machine is excellent practice for the real thing: installing Mac OS X on your actual computer. Don’t get too comfortable, though. Compared to most computers, Virtualbox virtual machines are very “vanilla”, meaning that they’re very compatible with Mac OS X in the first place. You can’t count on being that lucky with a real PC.

And even if you don’t plan on doing this for real, with a Hackintosh, it’s still a really cool thing to try out over the weekend.
