How to Install OS X Mountain Lion 10.8 on PC | Hackintosh

Advertisements

Guide to Install Mac OS X Mountain Lion 10.8 on Intel PC, laptop. Vanilla Installation guide to build Hackintosh / OSX86 with latest version of Mac OS X.

Apple just launched Mac OS X Mountain Lion 10.8 to general public and the build number is the same build number as the Golden Master. So this guide will work with both GM and Final release. First time hackintoshers are recommended to read the procedure twice or thrice. There is nothing technically complicated that isn’t clearly explained, but if you have any doubt or question post a comment below or ask us on our facebook page. We’ll try our best to help you out.

 Note : If you like our work, encourage us by sharing this post on Twitter, Facebook, Google + as much as you can.

Requirements :

  1. Running Mac OS X – This can be in the form of an existing hackintosh, a virtual machine (VMWARE) or  a regular Mac.
  2. A 8GB or larger USB flash drive.
  3. A copy of OS X Mountain Lion 10.8
  4. One / Two cup of Coffee and dedicated time
  5. An SSD or HDD to install OS X Mountain Lion 10.8
  6. Some Kexts, Packages and Installers. Don’t worry we collected all these files and packed in to a single Zip file for your convenience. Just click here (ML_OSx86_iHackintosh) and save this file to desktop.

Part ONE : Formatting Your Hard Drive.

  • If you are on windows you’ll need to use Disk Management. Open the start menu, and type in diskmgmt.msc or use Run.diskmgmt
  • Find your drive, right-click on it, and Shrink the HDD you want to install Mountain Lion on.
  • You can also add a separate HDD to Install Mountain Lion. Personally I prefer a separate HDD in my rig.

Part Two : Preparing your install Partition/Flash Drive.

  • Open Disk Utility and Select your USB flash Drive and format it as Mac OS Extended (journaled) and
    hit Erase button. Leave Disk Utility open, as you’ll need it later.1 Prepairing ML USB
  • Download Mac OS X Mountain Lion from the Mac App Store ($19.99)
  • The installer should show up in your Applications folder.
  • Right-click on the installer and hit “Show Package Contents”. Navigate to Contents > SharedSupport and locate a disc image file called “InstallESD.dmg”
  • Mount the InstallESD.DMG  (pirates just double click the .dmg you downloaded from internet)
  • Next We’ll need to run Show-Hide Files found in the ZIP file you’ve downloaded earlier.
  • Now launch Terminal.app and run this command in terminal
 1: open /Volumes/Mac\ OS\ X\ Install\ ESD/BaseSystem.dmg

3

  • Now Open Disk Utility again and  select your install partition/Flash Drive.
  • Click on Restore, Drag the Mac OS X Base System.dmg found on your desktop to the Source Window. Also drag your Install Partition/USB to the Destination Window and Click Restore. It’ll give you a warning about Erasing it click on Erase. Check the following screenshot to understand this step better.        5
  • Installation process will take 15-30 minutes, after installation you’ll end up with 2 “Mac OS X Base System” drives on your desktop. Figure out which one is your USB drive by Right-Click > Get Info and check the capacity as an indicator.
  • Open your flash drive and navigate to System > installation and you’ll find a link to Packages remove it, and create a new folder called  “Packages“.
  • Go to the original Mac OS X Install ESD and copy the contents of Packages to the folder you made in previous step.

Part Three : “Fixing” the Installation.

  • Copy to the Two .Kexts files found in the ML_OSx86_iHackintosh (downloaded earlier) folder to System > library > extensions
  • Next copy the OSInstall file to System > Library > PrivateFrameworks > Install.framework > Frameworks > OSInstall.framework > Versions > A and overwrite what’s already there. 6 replace OSInstall
  • Copy the OSinstall.mpkg to System > Installation > Packages overwrite what’s already there.
  • Run the Chameleon install package. Remember to select customized install and select all the Options/enablers needed (SMbios etc)
  • Copy over the Mach_kernel found in the root of the Mac OS X install ESD to the root of your Partition/USB drive.
  • Now move the Chamleon package to the root of the Partition/USB drive.

Part Four : Installing Mountain Lion from USB Drive.

  • Stick the USB drive in the computer you wish to install Mountain Lion and boot from your USB drive.
  • Chameleon boot-loader will pop up on your screen, highlight your flash drive and add -v, then push enter.
  • Follow the installer to install OS X to the desired partition.
  • Once the installer is finished it will reboot, on reboot boot back into the installer USB we need to fix some files before booting in to OS X.
  • From the installer go to Utilities and Terminal and type following commands one by one.
cp –R /System/Library/Extensions/NullCPUPowerManagement.kext /Volumes/YOURS_10.8_INSTALLATION_DRIVE/System/Library/Extensions/

cp –R /System/Library/Extensions/FakeSMC.kext /Volumes/YOURS_10.8_INSTALLATION_DRIVE/System/Library/Extensions/

reboot

NOTE:  Replace YOURS_10.8_INSTALLATION_DRIVE with the name of your install partition, mine was MLOSX86.

Part Five : Booting OS X 10.8

  • Boot from USB and select the Drive where you installed Mountain Lion to and boot verbose.
  • After a lots of text flyby, You’ll be asked to the setup your fresh installation. Go through that process to setup 10.8
  • Once you boot in to Mac OS X, run the Chameleon package and select all the Enablers you require and the SMBOIS.
  • You’re Done! Congratulations!!

Have Something To Say ?

    Can you please elaborate on the chameleon installation? In terms of what settings are needed to be selected? I’m able to boot of my USB drive, select base system and use the -v parameter, white text scrolls through for about 45 seconds and then the PC restarts?

    I’m stuck at Part Two during the Source/Destination process… When I try to copy the Mac OS X Base System the loading bar won’t move any further than “Verifying”… After 30 mins I cancelled the installation.
    I’m using OS X 10.8 VMware and a Kingston 16GB 3.0 USB Stick.

    Anyone got a solution for my problem?

    Hi. I boot from my flash drive which I have installed Mountain Lion on it. I can see graphical Chameleon boot-loader. When I choose second (-v in text mood) after installing Chameleon my screen gets dark (like when wire between monitor and case is disconnected). When I choose first this sentence appear “Cannot find Nvidia video” and after a few minutes I can see Apple brand on the screen and after many seconds again it gets dark.
    Can anybody help me?
    thanks.

      When I boot from the USB stick, the Chameleon loader starts just fine off the stick, but then when I type in -v for verbose and hit enter, I get this:

      Which then brings me right back to the bootloader. Any ideas?

    “When i enter -v when booting it gets to System Uptime in nanoseconds and then gets stuck. If i boot it without -v the apple logo appears and then it says you need to reboot.”
    Do you have already a solution for this?

    @Drew, the word “kernelcache” is misspelled in both lines. Did the program do that or did you do that when you retyped it? If the software did it maybe that is part of the reason.

    all your problems are for your motherboards. either running or installing on gigabite motherboards are now stable. i think thats for their bios. mac os cannot run on every bios so we cannot fix bios yet.

    Hello everyone and huge thanks to tha author of this Tuto!
    everything is going very well but didn’t understand the “Copy over the Mach_kernel found in the root of the Mac OS X install ESD to the root of your Partition/USB drive.
    Now move the Chamleon package to the root of the Partition/USB drive.” step!
    I found Mach_kernel and I copy past it to USB, is that it?
    For the Chamleon package, where to find it so I can move it to USB drive?
    Please help and thanx a lot again!

    My first problem (Chameleon said “no software to install”) was fixed by moving from Leopard to Snow Leopard to prepare the USB drive. No matter how many time I tried it on Leopard carefully following the instructions I always got the error “no software to install” when running the Chameleon pkg. But it worked first time on Snow Leopard.

    My new problem is my PC will not boot from the USB. I get:
    boot0: GPT
    boot0: test
    boot 0: test
    boot0: done
    boot1: error (and then it hangs with flashing cursor)

  22. lemontree August 10, 2012 Reply

    @alexg: for the issue “no software to install”, it seems that you need to copy the installESD.dmg file to the folder “/Applications” before running the Chameleon 2. I say it seems that because I am running the unibeast application and it says that thing.

  23. Squirrel61 August 8, 2012 Reply

    I followed the guide, using a Lion Virtual Machine in VMWare, but the computer does not boot from the stick. I’ll try to re-run Chameleon, hope that fixes the problem. Otherwise, I’ll retry the whole procedure on a “real” Hackintosh instead of a Virtual Machine.

  24. manbg August 7, 2012 Reply

    @Gerard After you type -v you should also try to add GraphicsEnabler=Yes so the whole line would look like this : -v GraphicsEnabler=Yes I had the same problem and that fixed it. Then I had another problem with the actual installation. When I go to Welcome screen and I hit Continue a message pops up saying something about missing essential software and that Install cannot continue. I hope anyone could help me about it please :)

  25. JJT187 August 7, 2012 Reply

    After a little more digging I found that just using the -v switch it goes blank at PCI Configuration Began. If I add npci=0×3000 it gets quite a bit farther. It goes black to quickly though I can’t tell where it stops. I see it loading “NVDAG****” twice then after the next line (which I can’t read becaue it goes black too fast) is where it stops.

    I’m getting the same issue. Screen goes black and the input light just blinks. I’ve tried all the suggestions listed above with no luck. Any other idea?

    hello, all!

    I have everything working fine after installing Mountain Lion on my iATKOS L2-based hackintosh running 10.7.4 following the instructions posted in this article. Although the preparation was a bit tedious; however, the final result was everything I hoped it would be. I just had the 10.8 install over the current version, so it’s not a fresh install. At first, I thought I’d have problems booting the OS since I really didn’t change anything (just used the STANDARD options) during the installation process. Anyway,thank you for this article.
    Reminder to all those concerned, don’t forget to run the SHOW-HIDE files through the terminal.app in order to see and manipulate the hidden files such as MACH_KERNEL. If you don’t run that, you won’t see them.

  29. Frank August 4, 2012 Reply

    @Allen: you need to open the app ‘ShowHiddenFiles’ which you can find from the zip and choose ‘Show Special Files’. Now the Mach_kernel will be visible. :D

    Also I am installing it on a 1 TB HDD which already having 3 partition of NTFS in which one having Windows 7 installed and using 4th partition for Mac , So will it work fine or have to do something extra ? ?

  32. alex August 3, 2012 Reply

    all goes well until “■Run the Chameleon install package. Remember to select customized install and select all the Options/enablers needed (SMbios etc)”

    I ran Chameleon .pkg in the directory with the unzipped files but after customizing and selecting usb as destination I get “instalation failed . .installer could not install the software becasuse there was no software to be found”

  33. Zach Elliott August 1, 2012 Reply

    @Allen Make sure you run ShowHideFiles from the folder you downloaded. Then click show special files and you will see the mach_kernal file.

    I ran the USB with the -v command and the screen just goes blank and black. There is signal to the display but it stays black. Now I tried just normally pressing enter and it loads up the apple but no loading or anything, it just stays there. I also tried with the -x command in safe mode and that gave me the same result of the apple just stuck there

    Double check part 4?

    As in:

    Part Four : Installing Mountain Lion from USB Drive.

    Stick the USB drive in the computer you wish to install Mountain Lion and boot from your USB drive.
    Chameleon boot-loader will pop up on your screen, highlight your flash drive and add -v, then push enter.
    Follow the installer to install OS X to the desired partition.
    Once the installer is finished it will reboot, on reboot boot back into the installer USB we need to fix some files before booting in to OS X.
    From the installer go to Utilities and Terminal and type following commands one by one.

    ?

    I did see Chameleon, and I did add -v to the install line… there is then a ton of text that scrolls off the screen, a bit of a pause whilst bluetooth is loaded, then the screen goes black.

    I do not get as far as ‘follow the installer to install OS X to the desired partition’.

    Thanks

    The name of the partition prior to the restore part where you put source as mac os x base system and destination as the name was “USB” and when I put:

    cp -R /System/Library/Extensions/NullCPUPowerManagement.kext /Volumes/USB/System/Library/Extensions/

    it gives me this huge “could not be found” error.

    So is the name of the drive “Mac OS X Base System”? Or what is was named before it was renamed to that.
