Easily Run Mac OS X 10.8 Mountain Lion Retail on PC with VMware Image – Simple Steps

VMware and VirtualBox made hackintosh easy by allowing us to work as separate virtual machine, rather than disturbing existing physical OS. After Apple has released the final retail version of Mac OS X 10.8 Mountain Lion, this VMware image made from latest version by a reliable source. The pre installed VMware image is created by souldevteam and all credits go to them. I’m here just explaining how to make it work and run Mac OS X 10.8 mountain lion retail version on VMware with Intel PC and Windows 7.

Sysprobs covered several hackintosh guides with VMware and VirtualBox here. Also we earlier published few articles based on souldevteam blog too .

Update: By Any chance if you are looking for latest OS X 10.9 Mavericks, read our below famous guides,

How to install OS X 10.9 Mavericks on VMware with Windows 8 & 7

How to use per-installed VMware image of OS X 10.9 Mavericks on Windows 8 & 7

This method is completely for testing and learning purpose only. Do not use this method on production environment or permanently for long term. You can’t get the all features of Mac OS X from this method as how it works on Apple hardware. We always recommend to buy Apple hardware to run Mac OS X.  Also, few users keep on asking about their Apps development and Xcode support on virtualized hackintosh. Frankly, I do not know whether these all will work on this platform, if it works, you are lucky.


What all Required to Run 10.8 Mountain Lion Retail VMware Image on Windows

1) Hardware Virtualization Technology (VT) enabled processor. I do not fully recommend VT pypasser (to skip this check) tool which is included in this download.

2) Pre installed VMware image with few tools. VMware unlocker and darwin.iso are important.

3) VMware workstation 8 or later versions


Easy Steps

1) Download ‘Mountain Lion 10.8 Retail VMware Image’ from owner’s site.

2) Use 7z program to unzip the download, after extraction the size should be around 6.2 GB


3) Check and make sure your physical computer processor supports Hardware Virtualization Technology (VT).  Read our previous guide about how to use VT checker tool and confirm it.

4) Use VMware unlocker (which will be available on same extracted location) and patch the existing VMware workstation 7 or 8 series. Use the correct version of unlocker. Read more about how to use VMware unlocker to get Mac OS X guest support.

After the patch, make sure you are getting Apple Mac OS X option as shown below.

5) Once the step 3 and 4 are succeeded, open ‘OS X 10.8 Mountain Lion.vmx’ from extracted location through VMware workstation ‘File –> Open’ menu.

open the VMX file

6) That should open the pre installed Mountain Lion retail VMware virtual machine. Before powering on, you can modify processor and RAM settings depending on available resources on physical computer. I have increased the RAM to 2GB and number of processor cores to 2 as I have core2duo physical processor.

changed settings

7) Now power on the virtual machine. If all settings are correct, the Mac OS X 10.8 virtual machine should start with initial setup screen of Language settings as below.

initial language selection screenThat’s it, we are almost done. After completing all initial settings (you can skip few too), you should land on mountain lion desktop without any issues.

I recommend to take a snapshot now before proceeding further.


Install VMware Tools on Mac OS X 10.8 Mountain Lion Virtual Machine – Intel PC, Windows 7

Network and sound worked out of the box without additional installations or settings.

To get more screen resolution sizes, VMware shared folder and slightly better performance, we need to install VMware tools on mountain lion virtual machine.

8.) To install, load the darwin.iso file to virtual machine’s CD/DVD drive. Darwin.iso located at same extracted place.

loaded darwin

Once it is loaded to CD/DVD drive, the virtual machine will automatically detect and load it on desktop as below.

Double click and run ‘Install VMware Tools’ application. You may need to enter your password and select the disk to continue the installation.

For some reasons, VMware tools installation failed on Mountain lion virtual machine, but nothing to worry. Press close and restart the virtual machine manually.

9) After virtual machine is restarted, you will find more screen resolutions under display settings. Also, the full screen mode (from VMware menu bar) will work now.

VMware Shared Folders on Mountain Lion 10.8 and Windows 7

Few users reported that drag and drop of files between Mac OS X guest and Windows host is not working even after VMware tools installation. Yes, it is not working and we can’t complain about it, because VMware is not officially supporting Mac OS X virtualization on non Apple hardware. So, we need to live with it.

But, if you like to transfer files between Mac OS X guest and Windows host frequently without any types of networking connectivity or network sharing, then you can use VMware shared folders feature. This will work only after VMware tools installation.

You can access specific folders or partitions of Windows 7 host OS thorough VMware shared folders from Mountain Lion guest OS. That will enable the file transfer back and forth easily. It is nothing to do with networking or network file sharing, it is completely a different technology.

To set it up, go to virtual machine’s settings and Enable the folder sharing first. Then, add the partition or folder of Windows host.

vmware shared folders settings Wait for some to mount this drive or folder inside Mountain Lion virtual machine.

You will find a new drive under computer on OS X. By opening the drive you can access the hosts’ shared drive or folder.

shared folder disk Depending on the mode you selected (with read-only or not), you can save the data too.

Enjoy and play around with 10.8 Mountain Lion retail version on VMware!.

  1. Drew I get the same problem………….

    i have followed all the steps and it gets to the grey Apple screen and does nothing from there, I have made sure VT is enabled in BIOS.
    my sytem details are as follows:

    Manufacturer Acer
    Model Acer Aspire M3910
    Processor Intel(R) Core(TM) i3 CPU 550 @ 3.2GHz 3.20GHz
    Installed Memory (RAM) 3.00 GB
    System Type 64-bit operating System

    would really appreciate if someone could point me in the right direction

  2. Please tell me how do I fix the error: “Mac OS X is not
    supported with binary translation. To run Mac OS X you need a host on
    which VMware Workstation supports Intel VT-x or AMD-V.”(I checked my
    CPU, it says Intel Virtualization Technology is supported)
    And when I try to run the bypasser, it always says that, “0 out of 11 patterns replaced atleast once. This patch may not work”

    Also I tried the Processor Check for 64-Bit Compatibility and it says my PC is compatible.
    Please help me with this issue >_<

  3. Works great!

  4. Hello, thank you for this guide. I am having performance issues and was hoping you might be able to provide some insight. Whenever I perform an action (such as loading a program, or launching the launchpad) it takes several minutes for the action to complete.

    In the VM settings I have 2.5 GB of ram allocated, and 2 core processors. I also tried enabling “accelerate 3D graphics” in VMPlayer, but that didnt seem to make a difference in performance. I am running VMWare Player 4, on a Windows 7 32 bit host with 8GB of ram and dual core 2.8ghz processor.

    The only step I was unable to follow successfully was running the VMWare unlocker (the batch file threw some error, which I can capture and paste here if you like). However, the Mac OS still loads and I can still use it, its just slow. Currently in the VM settings, under “General” the Guest operating system is listed as “Other” and the version drop down states “Mac OS X 10.7 64-bit”. Would this be causing the performance issues, or is the unlocker strictly related to trying to get vmware player to run the VM?

    • Please ensure you open the command prompt in Administrtor’s mode and execute the VMware unlocker. If you still got errors, suggest to reboot the PC (without opening VMware Player) and then try it again. You should always choose “Mac OS X 10.7 64-bit” when it is available.

      • Thank you for your reply and suggestion. I did run the unlocker as administrator. Here is the console output:

        The VMware Authorization Service service was stopped successfully.

        Mac OS X guest unlocker for VMware, version 7

  5. is it possible to improve the graphic performance? I’ve been trying all day with no results…
    On the system information i can see 128 MB of VRAM but according to the performance of the system I think is using less than that.

  6. Unable to open kernel device “\\.\VMCIDev\VMX”: Overlapped I/O operation is in progress. Did you reboot after installing VMware Workstation?

  8. Ran like a charm on both machines I tried it on…


    The shared folders isn’t working. VMWare workstation 9 doesn’t even show that option, which usually means that the guest doesn’t have the tools installed, but they are (reinstalled just to be safe).

    Any suggestions?

  9. Thanks for the post but have one major problem……………Everything worked fine right until i installed the VMtools. After installing the tools i get a lovely large Apple OSX login screen and about 2 seconds later the virtual screen goes mental and looks like a scrambled TV signal. Its like there is a sudden driver issue or something. When I go into VMware Worksation 9 preferences, select display and then disable the VMtools option, I no longer have the issue. SO it seems the display crashes when using the tools.

    I have:

    16GB DDR3 Ram
    i5 Processor
    External 2Gb graphics card

    VMware Workstation 9
    Vmtools 110
    OSX Mountain Lion 10.8.2

    Any Ideas?

  11. Hi,

    I am using ubuntu as my host machine and I have vmware workstation 9 on top of it. Can you please provide the vwmare workstation 9 unlocker for mac in ubuntu? I have been searching on net for ubuntu but all the sites are giving only for windows 7 and if it vmware workstation 8 in linux, which I am not able to use it. Please provide the unlocker for vmware workstation 9 in ubuntu(linux).


  12. December 7, 2012
    I have a Toshiba L630 Laptop, 8GB RAM, OSx 10.8 Mountain lion on VMWorkstation 9.0.1, under Windows 8-64bit, with Workstation Compatibility, and VMWare tools installed, and it all runs fine. Very impressive actually. I even have shared folders etc, and have already uploaded apps to iTunes…
    However. I can not get the sound to work. Nothing I do will show any sound devices available?
    Anyone have any solutions to this? Thanks

    • Solved.
      To change the audio device:

      Open the .vmx configuration file of the virtual machine using a text editor. For more information, see Tips for editing a .vmx file (1714).
      Locate this entry in the .vmx file:

      sound.virtualDev = “hdaudio”

      Change this entry to:

      sound.virtualDev = “es1371”

      Save and close the .vmx file.
      Start the virtual machine.

    • Probably not from what I read.
      I’d recommend 64bit, 8GB RAM minimum, fast processors, like dual/quad core anything.
      Having an extra OS in there really makes the machine work.
      Mine now hums along, and generally I use the Mac now in preference to the PC side.
      Especially by paying for Vmworkstation licence and Osx, both very cheap, you can use your valid appID etc for updates. There are a lot to start with.

  13. Does somebody know why I have problems with rendering.

    For example, I open safari, in the new tab, all the content is flashing and flashing, like the is taking a lot to render one single frame!

    8gb ram
    nvidia 230m

    • @jean

      It depends on what os you are based on perhaps, but I found this on the VMWare Communities board.
      If you have 3D turn it off perhaps, or if you are running on Win7, try
      Control Panel -> Internet Options -> Advanced -> Accelerated Graphics -> Use software rendering […]

      Re: Fusion + Win7 IE9 Rendering broken
      For those who cannot change the IE 9 settings of the ‘Use software rendering’ setting in Internet Options:

      I’ve had the same problem right after having installed Fusion 4. To fix, you need to edit the Windows registry.

      1. Close IE.

      2. In regedit.exe, find this (either by using the ‘Find’ command, or by manually navigating towards those keys)

      HKEY_CURRENT_USER\Software\Mic­rosoft\Internet Explorer\GPU

      There you’ll find the ‘Software Fallback’ key in two versions. One is called “SoftwareFallback” (for 32 bit Windows), the other “Wow64-SoftwareFallback” (for 64 bit Windows).

      3. If the value is “0”, change it to “1”. I did it for both keys but I guess it’s sufficient if you change the value only for the key appropriate to your Windows version (32 or 64 bit).

      4. Close the registry editor.

      5. Open IE 9 and enjoy.

      Hope this helps,

    • See my entry a bit further back up the list….

      To change the audio device:

      Open the .vmx configuration file of the virtual machine using a text editor. For more information, see Tips for editing a .vmx file (1714).
      Locate this entry in the .vmx file:

      sound.virtualDev = “hdaudio”

      Change this entry to:

      sound.virtualDev = “es1371″

      Save and close the .vmx file.
      Start the virtual machine.

  14. I’ve followed the directions, and it boots into OS X 10.8… after a while, maybe like 10-15 minutes. However, no sound available. Network works. Mounting the darwin.iso never loads via settings or even mounts via burned CD-R disc. I had to download the ISO through Safari and mount/install. Upon reboot, the Mac was booting SLOOOOOW… the spinning wheel was in super slow motion. I reset the virtual machine, and it’s spinning normally… but still, probably 10-15 minutes+ of waiting until it’s on the desktop or not. HELP! This is on a Dell Optiplex 990 minitower, Core i7, 16GB RAM, Radeon HD 6450

    • @Mark. If you haven’t fixed the slow problems yet…. It does take a while normally to load and unload anyway. But not usually 15 minutes. Sometimes it seems to be the host systems hardware settings that cause problems too. Especially the graphics rendering.
      Do you have the Mac settings for memory and graphics set properly. Set the memory just under the limit where it will start paging. If you let it page, it will take ages snd ages as it uses the HDD as a memory cache.
      As for the graphics, not sure. But most likely memory usage.
