Install Hackintosh Yosemite on PC/Laptop

1

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 is just might be for you. Right now, the newest iteration of OS X is 10.10, known as Yosemite. In this guide, we’ll show you how to install Yosemite on your PC with the newly released Downloadable “OS X Yosemite Installer” distribution

The advantages of Unibeast vs Yosemite Installer

Yosemite is a distribution, which is a copy of Mac OS X that has been modified to work with a PC. distributions are a popular Hackintosh alternative to Unibeast, a known installation tool which requires a retail copy of Mac OS X instead.

Using Hackintosh Yosemite Installer instead of Unibeast for Yosemite offers a far share of advantages. distributions, they’re actually the most convenient way to set up your Hackintosh:

  • You don’t need a real Mac. Unibeast is a Mac app, so you need to have an existing Mac OS X installation for it to work. This usually means that you either have to find a real Mac, or set up a Mac virtual machine. However, with Yosemite Installer, you can just set up everything from a Windows computer.
  • The post-installation is easier. By default, Yosemite Installer will automatically install necessary Hackintosh-specific kexts and drivers for your computer when you boot your Mac OS X installation for the first time. Unibeast requires you to do this manually, using the Multibeast tool. While the post-installation in Yosemite Installer isn’t perfect, it’s still a nice convenience.
  • You can install it on a hard drive that already has Windows installed. By default, the Mac OS X installer will not work with hard drives that were originally formatted in Windows. Therefore, if your computer’s hard drive already has Windows installed on it, you won’t be able to install Mac OS X on there. Normally, you can bypass this limitation on Unibeast by applying the MBR patch; however, Yosemite Installer does this for you automatically, saving you one extra step.
  • Yosemite Installer supports more hardware (including AMD). Normally, computers that use AMD processors are unsupported by Mac OS X. However, Yosemite Installer includes experimental “patched” kernels that may allow Mac OS X to work with these processors regardless.

Interested? Here are the requirements:


  • An existing Windows computer/Mac/Hackintosh: This is the computer where you will download and set up Yosemite Installer. The computer can run either Windows or Mac OS X; both operating systems will work.
  • A Hackintosh-compatible computer with an empty hard drive: This is the computer where you will install OS X Yosemite. It can be the same computer as the one mentioned in the previous point. If your computer already has Mac OS X installed, Yosemite Installer will just update OS X normally, without deleting any of your apps or files.
  • Yosemite Installer 10.10.1: Yosemite Installer is a distribution of OS X Yosemite that has been modified to work with PCs. You will need to use a BitTorrent client to download the disk image file containing Yosemite Installer, which is a little less than 6 GB in size.
  • An empty USB drive (8 GB or larger): In this guide, you will write Yosemite Installer onto a USB drive, and boot your computer from that drive to install OS X Yosemite. The USB drive must be at least 6 GB in size. Since you will need to erase all of the files on the USB drive, make sure to back up its contents first. You can reuse this USB drive for normal stuff after you finish installing Yosemite.
  • TransMac: ($48, 15-day free trial): If you’re using a Windows computer to set up Yosemite Installer, you need to use TransMac to write the disk image file onto your USB drive. You can just download the free trial.
  • Restore Yosemite.pkg: If you’re using a Mac to set up Yosemite Installer, you need the special “Restore Yosemite” app to write the disk image file onto your USB drive. .

Create your Yosemite Installer USB Installer

1a. Create your Yosemite Installer USB drive (Mac)

Follow this step if you’re setting up Hackintosh on a Mac or existing Hackintosh. Plug your USB drive into Mac OS X, and open Disk Utility (located in Applications->Utilities in your main hard drive). Select your USB drive in the sidebar of Disk Utility and erase the drive, with the “Format” set to “MS-DOS (FAT)”. You can rename the drive any way you want.

Next, make sure that your Yosemite Installer disk image file is in the same folder as “Restore Yosemite.pkg”. If “Restore Yosemite.pkg” is still in a ZIP file, double-click that file to unzip it.

Double click on “Restore Yosemite.pkg” to start the app. By default, the app will be aimed at your computer’s main hard drive (mine is named “Super Panda” in the screenshot below). You do not want this– instead, click through the installer until you reach the page with the “Change Install Location” button.

From here, change the install location of the app to your USB drive (mine is named “Macaroni” in the screenshot below).

Press the enter/return key. The app will ask for your system password. After you enter your password, it will begin writing the Yosemite Installer disk image onto the USB drive. This will probably take 20-40 minutes, though it may take longer, depending on the speed of your USB drive. Once it finishes, your USB drive will contain a fully bootable version of the OS X Yosemite installer.

NOTE: “Restore Yosemite.pkg” is very glitchy. If you can’t find the “Change Install Location” button on the first time that you run the app, restart your computer and re-run the app. 

1b. Create your Yosemite Installer USB drive (Windows)

Follow this step if you’re setting up Yosemite Installer on Windows. Plug your USB drive into your computer, and open TransMac. Find your USB drive on the left-hand column of the TransMac window. Right-click on the USB drive, and click “Format Disk for Mac”. This will delete all of the files on your drive and prepare it for Mac OS X.

Once your USB drive is done formatting, right-click it again and click “Restore with Disk Image”. A file selection window will pop up; choose your Yosemite Installer disk image file (it will probably be called “Yosemite-Zone.dmg”), and proceed. Now, TransMac will write Yosemite Installer onto your USB drive.

This will probably take 20-40 minutes, though it may take longer, depending on the speed of your USB drive. Once TransMac finishes, your USB drive will contain a fully bootable version of the OS X Yosemite installer.

Set up the parts of your PC

These procedures are necessary for a hassle-free installation:

  • 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.

Set up your motherboard’s BIOS

Essentially, the BIOS (or UEFI) is the settings page for your computer’s motherboard. From here, you can fiddle with how your computer hardware works– it’s often necessary to change a few basic settings in the BIOS or UEFI to get Mac OS X up and running. The BIOS standard is generally used by motherboards from before 2012, while the UEFI standard is used by motherboards made after that.

Not sure whether your computer’s motherboard uses BIOS or UEFI? Here’s a quick guide to differentiating between the two: the interface of BIOS is usually monochrome and entirely text-based. Meanwhile, the interface of UEFI usually has pictures and allows you to use your mouse pointer.

Depending on the brand and standard used by your computer’s motherboard, adjust your settings accordingly:

  • If you own a Gigabyte motherboard with Legacy BIOS: Guide to Setup Legacy BIOS for Hackintosh
  • If you own a non-Gigabyte motherboard with UEFI:
    • To access BIOS/UEFI Setup, press and hold Delete on a USB Keyboard while the system is booting up.
    • Load Optimized Defaults.
    • Set USB drive to the highest boot priority.
    • If your CPU supports VT-d, disable it.
    • If your system has CFG-Lock, disable it.
    • If your system has Secure Boot Mode, disable it.
    • If your system has OS Type, set it to Other OS.
    • Save and exit.

Once that’s done, plug in your Unibeast USB drive in your computer, and then restart your computer.

Boot into Yosemite Installer

Restart your Hackintosh, and plug in your Yosemite Installer 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 Yosemite Installer menu.

If you do not manage to reach the Yosemite Installer menu, check your motherboard’s BIOS settings to make sure that the changes you made in Step 3 were properly applied. If they were, but you still cannot boot from the Yosemite Installer 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 Yosemite Installer.

At the Yosemite Installer menu, press the enter key (or return key) to start the OS X Yosemite installer. The installer screen will take several minutes to load. If you are trying to install OS X Yosemite on a computer using an AMD processor, you’ll have to type the boot flag “/amd”, “/amd32”, “/amd64”, or “/amdfx (without quotation marks)– which flag you need depends on your specific processor, so test one flag a time.

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 Yosemite Installer menu, try typing any necessary boot flags before pressing the enter/return key. Check out our list of common boot flags and our guide to fixing boot problems with the verbose mode for reference.

Install Yosemite

Once you’ve entered the OS X Yosemite installer, you will come up to a hard disk selection page. This is where you choose where you want to install Yosemite.

If you’re installing Yosemite on a computer that has never been turned into a Hackintosh before (i.e. doesn’t already have Snow Leopard, Lion, Mountain Lion, or Mavericks installed), there won’t be any hard disk options to select. We’ll have to fix that. To do this, start up Disk Utility, which is located under the Utilities menu in the top bar.

You need to use Disk Utility to erase a hard drive partition so that OS X Yosemite can install itself on it. In the sidebar of Disk Utility, choose the hard drive partition where you want Yosemite 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 two hard drive partitions are called “Cool Stuff” and “Not Cool Stuff”, while my entire hard drive is called “21.47 GB VBOX HARDDRIVE”.

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.

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.

On the installation page for Mac OS X, 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 distribution becomes really useful: Yosemite Installer allows you to install extra Hackintosh drivers and kexts, straight from the OS X Yosemite installer. The “Customize” page essentially does the same thing as Multibeast Yosemite, though the layout (and most of the names of the options) are different.

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, and automatically enable audio and ethernet. For most computers, that will be enough.

If your computer already has Mac OS X installed and you are simply updating it to Yosemite, you can just uncheck all of these options. Mac OS X treats Yosemite as just another update– there’s no need to reinstall all of your kexts and drivers.

Once you’re done with the “Customize” page, install Yosemite. This will take at least 30 minutes.

Boot into Mac OS X

Once the installation finishes, remove your Yosemite Installer USB drive and restart your computer. At the boot screen, you’ll see an Apple icon for the hard drive where you installed Yosemite. Select it (use the arrow keys on your computer) and press “Enter”.

Yosemite will boot. Mission accomplished! Once again, if you get a kernel panic/loading error when you try to boot your new Yosemite 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 Yosemite Installer menu, try to type any necessary boot flags before pressing the enter/return key. Check out our list of common boot flags and our guide to fixing boot problems with the verbose mode for reference.

Once Yosemite has booted successfully, click through the Mac OS X setup screens until you reach the desktop. From here, Yosemite Installer will work its magic, and automatically install the rest of the Hackintosh-specific kexts and drivers from Step 5.
