If youre interested in running Mac OS X, but you dont want to pay ridiculous prices for a normal Mac, then a Hackintosh just might be for you. Right now, the newest iteration of OS X is 10.8, known as Mountain Lion. Installing Mountain Lion on a PC is pretty much the exact same as installing Mac OS X 10.7 (Lion). This guide is based off tonymacx86s method for installing Mountain Lion, except that we cover it with more detail (and pictures!).




Requirements:
A compatible computer: Not every computer will work with Mac OS X, even with the help of tools like Unibeast and Multibeast. Be sure to read the Hackintosh compatibility guide very carefully, to check whether or not your computer qualifies. The hardware requirements for OS X Mountain Lion are essentially identical to those for Mac OS X Lion; AMD processors and older 32-bit Intel processors (such as Pentium M) are not supported. If your computer already has Mac OS X Lion installed, Unibeast will just update Lion to Mountain Lion normally, without deleting any of your apps or files.

A separate hard drive: Mac OS X needs its own hard drive (a minimum of 10 GB of space is required, but at least 50 GB of space is recommended). Unibeast will not work on a hard drive where Windows was installed first. You can bypass this requirement by applying the MBR patch to Unibeast.

Unibeast (Free): Unibeast is a Mac program that modifies the official OS X Mountain Lion installer, and writes it onto a USB drive. You can then use this Unibeast USB drive to run the Mountain Lion installer on a PC. Unibeast works with Mac OS X Snow Leopard and newer; registration on tonymacx86.com is required to download Unibeast.

A Hackintosh with Snow Leopard/Lion already installed, a real Mac, or a Mac OS X virtual machine: Unibeast is a Mac app, so you need a computer with Mac OS X to run it. You could use a real Mac, if you own one. Alternatively, you could install Mac OS X Snow Leopard on your PC, and then follow this guide to update your PC to Mountain Lion (if your computer uses an Ivy Bridge processor, be sure to use iBoot for Ivy Bridge).

As one last option, you could install Snow Leopard on a virtual machine, and run Unibeast on there instead. Be sure to install the Virtualbox Extension Pack to view USB drives from your virtual machine. This method willprobably not work if your computer uses an Ivy Bridge processor (though I havent personally confirmed this).

OS X Mountain Lion ($20): The method used by this guide requires that you have a copy of the Mountain Lion installer app ($20) from the Mac App Store. Though the Mac App Store is included in Mac OS X 10.6.6 and newer, you have to be running 10.6.8 to download Mountain Lion. (you might be able to circumvent this requirement by spoofing your system version).

An empty USB drive (8 GB or larger): The USB drive used for Unibeast must be at least 8 GB in size. Since Unibeast will erase all of the files on your USB drive, make sure to back up its contents first. You can reuse this USB drive for normal stuff after you finish installing Mountain Lion.

Multibeast (Free): Multibeast is a collection of kext files that your Hackintosh will need to run properly, after the initial installation. Download it onto a USB drive. Be sure to download the newest version 5 of Multibeast, not the older versions 3 or 4 (which are for Snow Leopard and Lion, respectively).




1. Format your USB drive for Unibeast

Plug your USB drive into Mac OS X, and open Disk Utility (located in the Utilities folder in the Applications folder). Select the USB drive in the sidebar of Disk Utility, go to the "Partition" tab of Disk Utility, and create a new partition layout with 1 partition. Set the format to "Mac OS Extended (Journaled)". Name the new partition whatever you want.


Click the "Options" button before applying your new partition layout. It should be set to "Master Boot Record" by default. Keep it that way. Then click "Apply".




2. Run Unibeast



Download Unibeast and run it. Make sure that the OS X Mountain Lion installation app from the Mac App Store is inside your "Applications" folder of Mac OS X.






Select your USB drive as the installation destination (mine is named "Cheeseburger").










Click through the pages in the Unibeast installer, until you reach the following selection page with two options: "Legacy USB Support" and "Laptop Support". Select the first option if you use a first-generation Intel Core processor; these are Intel Core processors with 3-digit model numbers, such as the Intel Core i7-960 or i7-875K. Select the second option as well if youre installing Mountain Lion on a laptop. If neither of these options apply to you, you can simply skip this page by clicking "Continue".






Youll come up to the installation progress bar. Chances are, Unibeast will look like its stuck at the "Running package scripts" stage. Dont panic! This is normal-- during the "Running package scripts" stage, the progress bar is counting the number of files copied, but Unibeast is copying some really big files, so it takes forever for the number of copied files to increase.






Though Unibeast is supposed to only take 10-15 minutes to run, it may take up to an hour, depending on how fast your USB drive is.




3. Set up the parts of your PC

I covered these steps in my Snow Leopard guide, but theyre worth mentioning again:
Unplug all USB-connected devices from your computer before you begin the setup (except your keyboard and mouse). A faulty external USB hard drive can cause your Hackintosh bootloader to give you EBIOS errors on startup.
Open up your computer and unplug any extra internal hard drives that your computer has, besides the hard drive that youre installing OS X on. (Just unplug the hard drive SATA cables from your motherboard.)
If possible, connect your monitor to the DVI port of your computers graphics. The Mac OS X installer sometimes has problems with HDMI and VGA.
If your computer uses a AMD Radeon HD 6850, Radeon HD 6870, NVIDIA GT 430, GTS 450, GTX 550 Ti, GT 620, or GT 630 graphics card, unplug the card from your computer motherboard and use the integrated graphics on your CPU (or a different graphics card) instead. The Mountain Lion installer has serious compatibility issues with these graphics cards. You can reattach the card after you finish installing Mountain Lion.


NOTE: If youre installing Mac OS X on a computer that already has Windows installed on a separate internal hard drive, you may have to enable AHCI for Windows beforehand. Otherwise, Windows wont boot afterwards. Also, after installing Mac OS X, you should also sync your clock on Windows with Mac OS X.




4. Set up your motherboards BIOS

The BIOS is basically a settings page for your motherboard. To enter the BIOS on my own computers Gigabyte P67A-D3-B3 motherboard, I have to press the delete key when it boots (before the operating system starts). Different manufacturers set different keys for opening the BIOS.




NOTE: If you have a newer Gigabyte motherboard that uses the UEFI interface instead of BIOS, check out our guide for setting up the UEFI instead.






If your Hackintosh already has Mac OS X Snow Leopard or Lion installed, the only thing youll need to change in the BIOS is the "Boot Device", so that USB drives have highest priority.




If your Hackintosh doesnt have Snow Leopard or Lion installed yet, you have to change a few extra BIOS settings. Before starting, reset all of your BIOS settings to their factory defaults. On Gigabyte motherboards, you can reset your BIOS settings to their default by selecting "Load Optimized Defaults" on the main page of the BIOS. Once your BIOS is running on its defaults, you need to change these three settings:




Boot Device - Change the boot device of your computer so that "USB-HDD" is first. You need to do this for Unibeast to work. After you finish installing Mac OS X, you should change this setting back to default, so that "Hard Disk" is the first boot device (this optional, but it will speed up your boot times).






HPET - Change this to 64-bit.






SATA Control Mode (your BIOS might call this a different name) - This will probably already be set to "SATA", "IDE", or "RAID". Change it to "AHCI". Mac OS X only works with AHCI.







Keep in mind that the BIOS on most motherboards do not support using a mouse, so youll probably have to navigate through the BIOS with the arrow keys on your keyboard. Press "Enter" to change a selected option in the BIOS. On my Gigabyte motherboard, I have to press F10 to save my changes.




5. Boot into Unibeast

Restart your Hackintosh, and plug in your Unibeast USB drive. If things go well, your computer will boot from the USB drive instead of booting from your normal hard disk. You will then be able to view the Unibeast menu.






If you do not manage to reach the Unibeast menu, check your motherboards BIOS settings to make sure that the changes you made in Step 4 were properly applied. If they were, but you still cannot boot from the Unibeast USB drive, unplug your USB drive, and go back to Step 1. Reformat your USB drive with Disk Utility and try again. If all else fails, try using a different USB drive for Unibeast.




At the Unibeast menu, select the name of your Unibeast USB drive, by using the left/right arrow keys on your keyboard, and then press the enter key (or return key) to start the OS X Mountain Lion installer.






In the worst case scenarios, instead of loading the Mac OS X installer, you may end up at a dark gray screen that tells you to restart your computer (a kernel panic), or you may end up with a small crossed-out sign (a loading error). If you get a kernel panic/loading error (or if the Mac OS X installer simply wont start within 10 minutes), youll need to enter some boot flags.




To enter boot flags, manually restart your computer by pressing your computers power button. Then, once youve booted back into the Unibeast menu, try typing any necessary boot flags before pressing the enter/return key. Check out this list of common boot flags for reference ( PCIRootUID=0 and -x are two popular boot flags).






6. Install Mountain Lion

Continue, and you will eventually come up to a page that asks you for a "destination" for your Mac install. Select the hard drive that you want to install OS X Mountain Lion on, and continue.






If youre installing Mountain Lion on an empty hard drive, the hard drive selection box will be blank. Youll have to erase that hard drive with Disk Utility first (check out Step 4 of our Snow Leopard installation guide for more details).




Otherwise, select the hard drive you want to install OS X Mountain Lion on, and click "Install". Mountain Lion will now install itself. This will take at least 30 minutes.




Restart. If your Hackintosh already had Mac OS X Snow Leopard or Lion installed beforehand, you can unplug the Unibeast USB drive. Otherwise, keep the USB drive plugged in. At the boot screen, youll see an icon for the hard drive where you installed Mountain Lion. Select it (use the arrow keys on your computer) and press "Enter". Mountain Lion will boot. Mission accomplished!












Once again, if you get a kernel panic/loading error when you try to boot your new Mountain Lion installation (or if the installation simply wont start within 10 minutes), youll need to enter some boot flags.




To enter boot flags, manually restart your computer by pressing your computers power button. Then, once youve booted back into the Unibeast menu, try type any necessary boot flags before pressing the enter/return key. Check out this list of common boot flags for reference ( PCIRootUID=0 and -x are two popular boot flags).




7. Multibeast

Multibeast is a collection of kext files that youll need to install for your Hackintoshes to have sound, internet, a high resolution screen, and more. Different Hackintosh builds require different Multibeast setups, though most setups are very similar. Find out what Multibeast options you need to install. If you have a Gigabyte GA-P67A-D3-B3 motherboard like me, check out my own Multibeast setup.






If youre just updating your Hackintosh from Mac OS X Snow Leopard or Lion, you dont have to reinstall UserDSDT, Easybeast, or Chimera in Multibeast after installing OS X Mountain Lion. Mac OS X treats Mountain Lion as just another update-- this generally means that the only things you have to reinstall in Multibeast are audio kexts and ethernet kexts. You might also have to reinstall miscellaneous kexts, such as TRIM Enabler (for SSDs).








To run Multibeast in OS X Mountain Lion, 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. After running Multibeast, youll also probably want to change your BIOS settings back to normal (from Step 4).




Once thats done with, you should be running a fully functional copy of OS X Mountain Lion on your PC. Congratulations!http://www.macbreaker.com/2012/07/install-mountain-lion-unibeast.html

Previous OSX

Requirements

1. A computer with Mac OS X already on it � The reason for this is that we need to prepare the USB drive, and the only way to do this is within Mac OS X. So, you�re going to need to use somebody�s Mac for a while. You can also use Mac OS X inside of VMware Workstation (Windows or Linux), OR on your current hackintosh (if you have one). The bottom line is that you�re going to need some machine (again, it doesn�t need to be a Mac) to do this.
2. An 8GB (or larger) USB flash drive � I tried this on a 4GB flash drive, and it barely fails to meet the space requirements.
3. THIS file - Inside of that ZIP file are 3 other ZIP files that will be used.
4. Mac OS X Lion 10.7 DMG � You can download this from the Mac App Store. The DMG itself is located in Install Mac OS X Lion.app/Contents/SharedSupport. It�ll be best to move this file to your desktop.
5. About 20-30 minutes of time - Most of the time will be used up when copying files over to your flash drive. Using a USB 3.0 flash drive will speed things up quite a bit.
6. An already ready hard drive (or SSD) � You obviously need to install Lion to, so you�re going to need a hard drive or a solid-state drive that�s already partitioned and ready to go. You�ll be formatting the drive or partition in Disk Utility from the Lion installer, so you don�t need to specifically choose the filesystem just yet.

Instructions

1. Open Disk Utility (Spotlight, or /Applications/Utilities).
2. Select your USB drive�s partition in the left sidebar (the one that you�d like to put Lion on).
3. Go to the �Erase� tab.
4. For the format, set it to �Mac OS Extended (Journaled)�, give it a label, and click on the erase button.
5. Open Terminal.
6. Mount �InstallESD.dmg�, which can be found by looking at requirement 4 above.
7. Run the following command: open /Volumes/Mac OS X Install ESD/BaseSystem.dmg
8. Go back to Disk Utility.
9. Click on the �Restore� tab.
10. For the source, drag �Mac OS X Base System� from your desktop into the source box.
11. For the destination, drag your USB drive into the destination box.
12. Click on the restore button. This process will take anywhere from 5 minutes to 15 minutes, depending on the speed of your USB flash drive. At the end of the process, the label of your flash drive�s partition will change to �Mac OS X Base System�. Keep track of which is which, as there are now 2 �drives� labeled that.
13. Go to your USB drive in Finder, navigating to /System/Installation.
14. There should be a �Packages� symlink (which are basically shortcuts/links to another file or directory), so delete it.
15. Create a folder named �Packages�.
16. Go back to Terminal.
17. Run the following command: open /Volumes/Mac OS X Install ESD/Packages
18. Copy all of the files in the new Finder window over to the empty Packages folder that you created in step 15 above.
19. Extract all of the files from requirement 3 above to your desktop.
20. Open Extra Lion DP4 GM.pkg.zip, which will add Extra Lion DP4 GM.pkg to your desktop.
21. Open Extra Lion DP4 GM.pkg, installing the software to your USB drive.
22. Open Chameleon_2.0_RC5_r1083.pkg.zip, which will add Chameleon_2.0_RC5_r1083.pkg to your desktop.
23. Open Chameleon_2.0_RC5_r1083.pkg, installing the software to your USB drive. Ignore the available packages (in other words, install only �Chameleon�).
24. Open Lion_OSInstall_GM.tar.bz2, which adds a �System� folder to your desktop.
25. On your USB drive, navigate to /System/Installation/Packages.
26. In the extracted �System� folder, navigate to /System/Installation/Packages.
27. Copy the �OSInstall.mpkg� file from the extracted folder on your desktop over to the Packages folder on your USB drive, overwriting the one that�s already there.
28. On your USB drive, navigate to /System/Library/PrivateFrameworks/Install.framework/Frameworks/OSInstall.framework/Versions/A.
29. In the extracted �System� folder, navigate to /System/Library/PrivateFrameworks/Install.framework/Frameworks/OSInstall.framework/Versions/A.
30. Copy the �OSInstall� file from the extracted folder on your desktop over to the �A� folder on your USB drive, overwriting the one that�s already there.

Note: In some cases you may need additional boot flags to get to the installer. If you have an unsupported graphics card, youll need to add GraphicsEnabler=No. If you have an ATI Radeon 6670 installed youll need to add PCIRootUID=0. You can just type these in at the boot option screen before you press enter to choose "USB" and boot into the installer.
