Introduction: How to Install OS X Mountain Lion on Your PC With IAtkos

Picture of How to Install OS X Mountain Lion on Your PC With IAtkos

If you're interested in running Mac OS X, but you don't want to pay ridiculous prices for a normal Mac, then a Hackintosh just might be for you. In this guide, I'll show you how to install Mountain Lion on your PC with the iAtkos distro.

Distros are pirated copies of Mac OS X that have been modified to work with a PC. If you don't have any qualms with the legal issues regarding distros, they're actually the most convenient way to set up a Hackintosh. Thanks to MacBreaker for providing the original instructions.

Step 1: Requirements

- An existing Windows computer/Mac/Hackintosh: This is the computer where you will download and set up iAtkos. Either Windows or Mac OS X will work. If you're using a Windows computer, it needs to have a DVD/Bluray burner (just about every DVD/Bluray drive nowadays can act as a burner, too).


- A Hackintosh-compatible computer with 10 GB+ of free space: This is the computer where you will install OS X Mountain Lion. It can be the same computer as the one mentioned in the previous point. If your computer already has Mac OS X Lion installed, iAtkos will just update Lion to Mountain Lion normally, without deleting any of your apps or files.

However, not every computer will work with Mac OS X. Be sure to read the Hackintosh compatibility guide (will be posted soon) very carefully, to check whether or not your computer qualifies. Also, OS X Mountain Lion takes up about 10 GB of space on its initial installation, so the computer where you install Mac OS X must have at least 10 GB of space in its hard drive. However, that's only the bare minimum; if you plan to install Mac OS X for day-to-day use, I recommend allocating at least 50 GB of space. It's preferred that you use a completely empty hard drive for this, but if your computer already has Windows installed on your hard drive, be sure to create an appropriate hard disk partition for OS X Mountain Lion beforehand (by following Step 1 of my guide to MBR partitions) (will be posted soon).

- iAtkos ML2 (Free): iAtkos is by far the most popular distro of OS X Mountain Lion. I won't go into details, but you can download it from just about any bittorrent website by using a bittorent client (it's about 5 GB in size). The standard method of installing Mountain Lion on a PC requires you to modify a retail copy of OS X Mountain Lion with Unibeast, but iAtkos already does all of this for you. In this guide, you will write iAtkos onto a USB drive or DVD, and boot your computer from iAtkos to install Mac OS X.

This guide describes how to install iAtkos ML2. You can also use iAtkos ML3, an updated version that only works with motherboards with UEFI (a guide regarding motherboards with UEFI will be posted soon). If you're not sure which version to use, just use ML2.

- A dual-layer DVD, Bluray disc, or empty USB drive (8 GB or larger): If you are setting up iAtkos from Windows, you have to write iAtkos onto a dual-layer DVD or Bluray disc (normal DVDs don't work because iAtkos is slightly too large).

However, if you're setting up iAtkos from Mac OS X, you can use a 8 GB or larger USB drive instead of a dual-layer DVD. You will need to erase all of the files on your USB drive beforehand, so make sure to back up its contents first. You can reuse this USB drive for normal stuff after you finish installing Mountain Lion. You cannot write iAtkos onto a USB drive from a Windows computer. If you really want to use a USB drive from Windows, install Mountain Lion on a virtual machine (a newer guide for this will be posted soon) and set up an iAtkos USB drive on there instead. Be sure to install the VirtualBox Extension Pack to view USB drives from your virtual machine.

- TransMac ($48, 2-week free trial): If you're using a Windows computer to set up iAtkos, you need to use TransMac to write ("burn") the iAtkos disk image file onto your dual-layer DVD or Bluray disc. You don't actually need to purchase TransMac; the free trial works fine.

- Carbon Copy Cloner ($40, 2-week free trial): If you're using a Mac to set up iAtkos, you need to use Carbon Copy Cloner to write the iAtkos disk image file onto your USB drive. You don't need to actually purchase Carbon Copy Cloner; the free trial works fine.

- Multibeast (Free): Multibeast is a collection of kext files (will be mentioned later) that your Hackintosh will need to run properly, after the initial installation. If you're using a Mac to set up iAtkos, you will also need Multibeast before the initial installation. 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).

Step 2: Create Your IAtkos USB Drive (Mac)

Picture of Create Your IAtkos USB Drive (Mac)

- Follow this step if you're setting up iAtkos on a Mac or existing Hackintosh. 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" (this step is shown in the first picture).

- Open your downloaded iAtkos disk image by double-clicking it; this file will probably be named "iATKOS_ML2.dmg". Then, start Carbon Copy Cloner, and set the iAtkos disk image as the "Source" and your USB drive as the "Destination". In the second picture, my USB drive is named "Whatever". This will write all of the contents of the iAtkos disk image onto your USB drive. This will take 15 minutes to an hour, depending on the quality of your USB drive (this step is shown in the second picture).

- Once Carbon Copy Cloner is done, your USB drive will contain a fully-functional OS X Mountain Lion installer. However, it's still unbootable on PCs. To fix this, open Multibeast and select the USB drive as the installation location. Select Drivers & Bootloaders -> Bootloaders -> Chimera, and run the Multibeast installer (this step is shown in the third picture). NOTE: If Multibeast doesn't give you the chance to choose the installation location, click past the pages in Multibeast, until you reach the page with the "Change Install Location" button.

Step 3: Create Your IAtkos DVD (Windows)

- Follow this step if you're setting up iAtkos on Windows. Insert your dual-layer DVD into Windows, and open TransMac. Click File -> Open Disk Image. In the Windows Explorer window that pops up, select your downloaded iAtkos disk image; this file will probably be named "iATKOS_ML2.dmg" (this step is shown in the first picture).

- Your iAtkos disk image will pop up in the left sidebar of the TransMac window. Right-click on it, and click "Burn to CD/DVD". Then burn the disk image (this step is shown in the second picture).

- This process may take up to an hour (or more, depending on the speed of your DVD burner). Once TransMac finishes, you will have a fully bootable DVD version of the iAtkos Mountain Lion installer.

Step 4: Set Up the Parts of Your PC

Picture of Set Up the Parts of Your PC

I covered these steps in my Snow Leopard guide (which will be posted soon), but they're 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 you're 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 computer's graphics. The Mac OS X installer sometimes has problems with HDMI and VGA.

NOTE: If you're installing Mac OS X on a computer that already has Windows installed, you may have to enable AHCI for Windows (I will post a guide for this soon) beforehand. Otherwise, Windows won't boot afterwards. Also, after installing Mac OS X, you should also sync your clock on Windows with Mac OS X (I will make a guide for this soon).

Step 5: Set Up Your Motherboard's BIOS

Picture of Set Up Your Motherboard's BIOS

The BIOS is basically a settings page for your motherboard. To enter the BIOS on my own computer's 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. The initial screen is shown in the first picture.

NOTE: If you have a newer Gigabyte motherboard that uses the UEFI interface instead of BIOS, check out my guide for setting up the UEFI instead (I will post a guide about motherboards with UEFI soon).

If your Hackintosh already has Mac OS X Snow Leopard or Lion installed, the only thing you'll need to change in the BIOS is the "Boot Device", so that the iAtkos installer has highest priority.

If your Hackintosh doesn't 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 - If you're using an iAtkos USB drive, change the boot device of your computer so that "USB-HDD" is first. If you're using an iAtkos DVD, change "CDROM" to first. You need to do this for iAtkos 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) (this step is shown in the second picture).

HPET - Change this to 64-bit (this step is shown in the third picture).

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 (this step is shown in the fourth picture).

Keep in mind that the BIOS on most motherboards do not support using a mouse, so you'll 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.

Step 6: Boot Into IAtkos

Picture of Boot Into IAtkos

- Plug your iAtkos USB drive into a USB 2.0 port on your computer (USB 3.0 doesn't always work), or insert your iAtkos DVD into your DVD drive. Restart your computer. If things go well, your computer will boot into iAtkos instead of booting from your normal hard disk. You will then be able to view the iAtkos menu (this step is shown in the first picture).

- If you do not manage to reach the iAtkos menu, check your motherboard's BIOS settings to make sure that the changes you made in Step 5 were properly applied. If they were, but you still cannot boot from iAtkos, go back to Step 2 (if Mac), Step 3 (if Windows) of this guide and try again with a different USB drive or DVD.

- At the iAtkos menu, select the name of your iAtkos USB drive/DVD, 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 (this step is shown in the second picture).

- 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 won't start within 10 minutes), you'll need to enter some boot flags.

- To enter boot flags, manually restart your computer by pressing your computer's power button. Then, once you've booted back into the iAtkos menu, try typing any necessary boot flags (I will post a guide about boot flags) before pressing the enter/return key. Check out this list of common boot flags (will be posted soon) for reference ( PCIRootUID=0 and -x are two popular boot flags).

Step 7: Install Mountain Lion

Picture of Install Mountain Lion

Once you've entered the OS X Mountain Lion installer, you will come up to a page that asks you for a "destination" for your Mountain Lion installation (this step is shown in the first picture).

If you're installing Mountain Lion on a computer that has never been turned into a Hackintosh before (i.e. doesn't already have Snow Leopard or Lion installed), the hard drive selection box will be blank. We'll have to fix that. To do this, start up Disk Utility, which is located under the Utilities menu in the top bar (this step is shown in the second picture).

You need to use Disk Utility to erase a hard drive partition so that OS X Mountain Lion can install itself on it. In the sidebar of Disk Utility, choose the hard drive partition where you want Mountain Lion installed, and erase it by using the "Erase" tab. You can also just erase the entire hard drive (this is the preferred solution if you don't plan to dual-boot Windows and Mac OS X from the same hard drive). In the screenshot below, my hard drive partition is called "disk0s2", while my entire hard drive is called "21.47 GB VBOX HARDDRIVE" (this step is shown in the third picture).

When erasing, the format should be set to "Mac OS Extended (Journaled)". You can also partition the hard disk by using Disk Utility's Partition tab.

NOTES:

- Mac OS X cannot boot from a partition that's larger than 1 TB in size, so if you have a 2 TB hard drive, you will have to partition it.

- Unlike the default OS X Mountain Lion installer, the iAtkos version of the Mountain Lion installer works with MBR partitions (I will post a guide about MBR partitions soon) by default. If your hard disk uses the MBR partition scheme, iAtkos will install itself onto there without the need for prior modifications.

- The iAtkos version of the Mountain Lion installer also works with software RAID 0 arrays by default. If you want to set up your Hackintosh's hard disks in a RAID 0 array, simply create an array by using the Disk Utility app inside the iAtkos installer (see Step 1 of our RAID 0 guide). iAtkos will install itself onto there without the need for Steps 2-5 of our RAID 0 guide (I will post a guide about RAID soon).

On the installation page for Mac OSX, the hard disk/disk partition should now be showing up. Select it, and then click the "Customize" button on the bottom left. This is where using a distro becomes really useful: iAtkos allows you to install extra Hackintosh drivers and kexts (I will post a guide about kexts soon), straight from the Mac OS X Lion installer. The "Customize" page essentially does the same thing as Multibeast (I will post a guide about the use of Multibeast soon), though the layout (and most of the names of the options) are different (this step is shown in the fourth picture).

However, choosing the right options from this page can be really tricky, so unless you're absolutely certain about which drivers and kexts you need to install for your computer, I don't recommend installing too much stuff from here. The default selection will enable Mac OS X to boot from the hard drive without any assistance; it may also enable sound and ethernet in OS X. For most computers, that will be enough (at least for the initial installation). If you wish to install more, refer to my guide to Multibeast (I will post a guide about the use of Multibeast soon). Otherwise, you can figure out the rest in Step 6, where you'll actually set up your Hackintosh with Multibeast.

After you're done with the "Customize" page, install Mountain Lion. This will take at least 30 minutes (this step is shown in the fifth picture).

Once the installation finishes, remove your iAtkos USB drive/DVD, and restart. At the boot screen, you'll 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!

The sixth picture shows the final screen.

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 won't start within 10 minutes), you'll need to enter some boot flags.


To enter boot flags, manually restart your computer by pressing your computer's power button. Then, once you've booted back into the iAtkos menu, try type any necessary boot flags (I will post a guide about boot flags soon) before pressing the enter/return key. Check out this list of common boot flags (I will post this list soon) for reference ( PCIRootUID=0 and -x are two popular boot flags).

Step 8: Multibeast

Picture of Multibeast

Multibeast is a collection of kext files that you'll 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 (I will post a guide about Multibeast options soon). If you have a Gigabyte GA-P67A-D3-B3 motherboard like me, check out my own Multibeast setup (which I will post soon).

If you're just updating your Hackintosh from Mac OS X Lion, you don't 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) (I will post a guide about all what you need to know about SSDs for Hackintoshing soon).


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, you'll also probably want to change your BIOS settings back to normal (from Step 5).


Once that's done with, you should be running a fully functional copy of OS X Mountain Lion on your PC. If you plan on updating Mac OS X in the future, check out my guide to updating your Hackintosh (I will post this guide soon). Congratulations!

It's a problem with PRAM and NVRAM...Try resetting them...Just google for it or on youtube...It's easy but to be timed perfectly...Good luck...!!

SanjayR (author)hacki312014-11-15

unplug net connection and try 100% work.

Omar Amir (author)hacki312014-11-04

From what I see, you're supposed to change the GraphicsEnabler into 'Yes'. Regarding the username and password, didn't you register them before you come to this screen?

Hi,

I have been trying to load iATKOS onto a GA-Z68MA-D2H-B3 mother board with 16GB of RAM and an Intel Core i7 CPU. My board is slightly different than the one in your instructions. I am making up the iATKOS Usb on a 27 inch iMac running Mavericks OS X. I am getting through to the 'boot:' level where it says Press enter to start up Darwin/x86. I do that and get the following error message. 'Can't find /mach_kernel. Press a key to continue..." When you press any key to continue it takes me back to the boot:
Any ideas what I should do or what i have done wrong?

Ben15Lee14 (author)virachoca2014-12-27

Hi virachoca, to answer your question, it's simple to know that the software when booting just cannot find the files required resulting for it to halt.


To find the missing /mach_kernel, during boot where you're asked to press enter to startup Darwin/x86, press F8 instead and enter this following command: /System/Library/Kernels/kernel

If that command didn't work reboot your computer and do the same as mentioned above but enter this following command: /Extra/mach_kernel

Hope that works!

Omar Amir (author)virachoca2014-01-08

Hi,

Well this could be caused by several reasons. I will give you some instructions to follow and you should try some of them and see which one fixes this problem. My first suggestion is to go back to Step 2 of this guide and try again with a different USB drive and make sure you follow its step correctly. If this doesn't work, then this might be a caused by a kernal panic, in this case, you'll need to enter some boot flags, try first typing mach_kernel while booting, if it doesn't work, try booting with -x, -x boots into safe mode so we can then know what's the problem. My second suggestion is your motherboard. My instructions are for BIOS motherboards, is your motherboard using the UEFI interface? If yes, tell me, so I can send you instructions for it. My third suggestion, actually it's a just a note, Mac OS X cannot boot from a partition that's larger than 1 TB in size, so if you have a 2 TB hard drive, you will have to partition it. I mentioned that in the instructions if you read it all beforehand. Also, what graphics card do you use? As AMD needs specific boot flags to boot, but my greatest certainty is that it will work if you booted with the mach_kernel boot flag, just start typing when booting and it should work. That's all what I have in my mind, try them, if it works or if it does not, please tell me.

Thank you.

Yes! This is another way of installing OS X :D

seshasaimaddela (author)2014-04-24

I have Installed iAktos ML2 on my Dell N5010 Laptop, i got a message like Installation is Successful and restarting your computer in 10 seconds. after restart i loops in the boot screen where i can only see Apple Logo (as i customized to have original apple logo in options). Any Suggestion will be more helpful to me

TanQ !!!

Are you sure you've followed the last steps 100% correct? Also, be patient as the first time it boots, it stays on the Apple logo for a few minutes.

I have followed the steps correctly and waited almost for 4 hours, but no luck :(

Try booting with: "GraphicsEnabler=No -x -v". There is an option in Multibeast for this, but you have to get there first. You type it before hitting enter at the Chimera bootloader screen. Try booting by using -x if the first one didn't work.
