Picture of How to Run Mac OS X Inside Windows Using VirtualBox
NOTE: This tutorial is now considered outdated and I've published a new instructable with a newer, better and more efficient method to install Mac OS X on your PC, not RUN it! Please refrain from using this tutorial and follow the New One!

Even if you're a Windows user, you've probably thought about trying the Mac OS X. Maybe you'd like to test OS X before buying a Mac or building a Hackintosh, or maybe you just want to run an app on your Windows machine which is only exclusive for the Mac OS X. Whatever your reason is, you can actually install and run OS X on any Intel-based Windows PC with a program called VirtualBox. Here's how.

Running OS X on your Windows desktop will take a bit of work, but it's pretty easy to do and the final product is quite outstanding. Thanks to Macbreaker and Lifehacker for providing the original instructions! To cut to the chase, here's how to do this.

Step 1: Requirements

Before you start the installation process, you’ll want to gather the following:

- A PC running 64-bit Windows with at least a dual-core processor and 4GB of RAM. Mountain Lion is 64-bit, and thus requires your copy of Windows to be 64-bit. If you’re on a 32-bit version of Windows, you can install Snow Leopard instead (Google it as this instructable is for Mountain Lion not Snow Leopard). Note that your processor also needs to support VT-x. This list should help you find out whether yours does.

- VirtualBox and the VirtualBox Extension Pack: VirtualBox is my favourite virtualisation tool for Windows, and it’s completely free. VirtualBox doesn’t officially support OS X, but it’s actually very easy to get up and running. You should download the main program and the Extension Pack, which will give you support for USB devices.

- A hacked Mountain Lion disc image. Sadly, this won’t work with a vanilla Mountain Lion installer, so you’ll have to find a compatible hacked version. The hacking group Olarila has put a great installation ISO together, and you can find it by searching Google. If that doesn’t fit well with you, you can head over to the Mac App Store and buy a legit copy for yourself, so you can at least pirate with a clear conscience.

- The HackBoot 1 and HackBoot 2 ISO files. Each one has it's own function which you'll know later. However, both will help you boot into the installation.

- Mulitbeast 4, which will help you get audio and other things working correctly after installation. You’ll need to register for a free account over at Tonymacx86.com to download this. Make sure to download MultiBeast 4 — it’s labelled “Lion”, but for our purposes the Lion version works better than the Mountain Lion version.

NOTE TO ALL WHO ARE FOLLOWING THIS TUTORIAL: I am working on a newer, better and more efficient tutorial to install Mac OS X Directly on your PC, not inside a virtual machine.
Some of us are not interested in dual booting. Is there a way to make the VM stable?
Omar Amir (author)  dtanders1 year ago

Yes, there is! I am working on a new tutorial to install Mac OS X on a VM. I am still going through it, it's currently undergoing some tests, but it works as a charm. I'll post that 'ible soon, stay tuned!

This may be a noob question, but why don't you just make the VM and then export it using Virutalbox's Export appliance feature to a file sharing site, or just upload the files that VM is made of. Unless of course this is because you simply don't have a way to upload such large files to the web.

Omar Amir (author)  randomranger1 year ago

There are several reasons behind not doing this. Firstly, not all people using this method have the same memory (RAM). For example, if you allocated your VM RAM to 4GB and you have a total of 6GB, not all people have 6GB, so they will have to create the VM from scratch. Secondly, with my current internet speed, it would take me a month (maybe more) to upload 13GB (which is the size of the finished VM). Thirdly, this is a tutorial, it is made to make people understand how it works and how to create one, but not just to have it ready.

I get as far as the disk image as you see of HackBoot but it says it's missing the kern file to load the OS to the system. Please assist or provide a link to the OS for me to install.

Did you change your BIOS settings?

hfahmed581 year ago

in between of step I get Suck here:

as per your guideline I perform

Step 3: Go back to the HackBoot boot screen and press F5. It should reload the

boot menu, this time showing you an “OS X Install DVD”.

& Till here I completed successfully but when I pressed enter at “OS X Install DVD”. It shows me a black screen with error.

Are you sure you chose the hacked Mountain Lion ISO?

AlfR1 Omar Amir3 months ago

What do you mean by "the hacked Mountain Lion ISO"?

I downloaded a .zip tjat does not contain any ISO...

Thanks for your assistance!

Omar Amir (author)  AlfR13 months ago

It's the ISO file of OS X that you are going to use. Try to extract the .zip to find if there's an ISO file, if not, message me and I'll guide you further.

AlfR1 Omar Amir3 months ago

Thanks for getting back to me, Omar.

Yes, I downloaded Mountain Lion 4.7.0 and 5.5.5, extracted the files and can not find any .ISO file.

What can we do?

Omar Amir (author)  AlfR13 months ago

I'll send you a private message with the link.

AlfR1 Omar Amir3 months ago

Ok, thank you so much, I'll wait for it.

yes, i downloaded from torrent by hotiso

Omar Amir (author)  hfahmed581 year ago

I didn't mean that. I meant during this step, you have to click on the CD icon at the bottom of the program and choose the hacked Mountain Lion ISO, did you do that?

I just had the same problem , i hope you have finished your exams and help me out . I did absolutely as per instructed .

When i press F5 nothing happens !!!!!

I am on 64 bit and I tried to press fn+f5 and tried shift+f5 , alt+f5, ctrl+f5, everything !! but in vain

Thanks in advance for your help :)

Omar Amir (author)  omar.saab.9611 months ago

It's not about the F5 button. You just need to refresh the screen.

Try to disable EFI in the "System" options of your VM

I am getting stuck when I boot with Hackboot 2 ISO. The last thing to show in the console is "Ethernet [Intel8254x]" Link up on en01...." Any suggestions??

Omar Amir (author)  osuhickeys1 year ago


No need to post the comment twice my friend, I'll be answering, so please be patient. Anyways, try booting by typing the line below in the chameleon screen

-v GraphicsEnabler=No

I've really realized that installing OS X is way more better than emulating (VM), so I'll be posting a tutorial on how to install the latest OS X on your PC (not emulate/VM), but I'm just busy these days with my exams, but I'll be posting the 'ible soon. Stay tuned!

Sorry for the double post. I thought maybe I did not do something correctly when it still was not showing up after a few minutes. Tried your suggestion with the same result. The end of the line says debug [796d,bc08,0de1,1e00,01e0,3c00]

I am getting stuck at the Hackboot 2 ISO. The last thing to show on the console is "Ethernet [Intel8254x]" Link up on en01....". It never goes any farther so I never get booted into OS X. Any ideas?

When I try to click on OS X Install Disc and then press ENTER, the text in the top left-hand corner just says:

Mach-0 file has bad magic number.

Then it goes back to show the OS X Install Disc option.

How to fix this?

Omar Amir (author)  gr4y1 year ago

You have to use the latest multibeast 4.6.1 with easybeast and system utilities checked. When your boot loader is corrupt you have to install the OS again.

I have the same problem as haza4best. The boot process is stuck at the grey apple logo and nothing happens. I did delete the kext file and activated / deactivatet the hackboot2 iso as described. Nevertheless, the resolution (fullscreen widescreen) is okay. This is also my second attempt, but without success.... As soon as I reactivate hackboot2 I can start the system, but without the large resolution.
Omar Amir (author)  Totaltimo1 year ago
Same answer. I have just realized now that this tutorial could be considered as an outdated tutorial due to the fact that it is very buggy, so I'm working on a new one, so please be patient. I am sorry if that did not work, but this is a bug as it doesn't occur to all who follow this tutorial, just some of them.
