[Guide] How to Install Mac OS X Snow Leopard in VirtualBox with Non Apple, Intel PC

After several days of attempts and findings, finally, I managed to install Mac OS X  Snow Leopard in VirtualBox 3.2 in non-Apple Intel PC.  This guide explains step by step methods involved in how to install snow leopard in VirtualBox 3.2.

This method is completely for testing and learning purpose.  Do not use for permanent or production use. Please buy the original Mac OS and Apple hardware. Oracle VirtualBox 3.2 officially supports Mac OS X as the guest on Apple hardware only. But still, it’s possible to install Mac OS X on non-Apple hardware with different bootloaders


UPDATE – 17-02-2011

Intel i-series processor users- Check this other guide with three methodssuitable for Intel i3,i5 and i7 processors.
Check this post – This same guide re-written with several major issues fixed and how to update to 10.6.5
When you updating to latest 10.6.6, make sure to check few considerations at end of this guide.

The good thing is, you do not require any hacked Mac OS X installation DVDs or ISO files. Use your original Snow Leopard retail DVD or ISO file.

Required Products to Install Mac OS X Snow Leopard 10.6.3 on Oracle VirtualBox 3.2

1) Oracle VirtualBox 3.2 ( Read more and download from here)

2) Mac OS X 10. 6 Snow Leopard Retail DVD or ISO

3) EmpireEFIv1085.iso for Intel Processors (This is the boot loader we will be using to boot Mac, download the correct version here)
Updated- EmpireEFI Boot loader for AMD processor

4) VT Checker (Read more here and make sure Hardware Virtualization is enabled is Host BIOS)

5) Sound driver (Mentioned under sound)

Demonstration PC configuration

1) Intel Core2Duo 2.66GHz (VT Enabled, 64 Bit Architecture supports)

2) 3GB RAM

3) Intel P35 Chipset

4) Windows 7 32 Bit

Step by Step Installation of Mac 10.6.3 on VB3.2

1) Create a Mac OS X Virtual Machine with following configuration ( If you have latest VB, then select Mac Server version)
More information on installing SL on VB 3.2.6

install Mac os x Snow Leopard on VirtualBox

Memory – Minimum 1GB
Processor Cores – 1 or more (Change it to one core if you face any issues. Two cores worked for me)
Enable PAE/NX, VT-x,
Nesting Page – Enabled
Enable IO APIC and Enable Absolute pointing device.
Remove Enable EFI. Built-in EFI loader may work with Apple hardware only.

install Mac os x Snow Leopard on VirtualBox

Enable 3D Acceleration under display and setup maximum video memory.
Storage Controller type ICH6 and create a 20 GB Hard disk.

2) Mount empireEFIv1085.iso to CD drive. Make CD ROM as the first boot device. Keep your Snow Leopard DVD or ISO file ready.

3) Start the virtual machine. When the following screen appears, eject loader ISO and load Mac installation DVD or ISO.

To do it, right click on CD drive and select drive or ISO image.  Wait a bit, Press F5 and ENTER Key when DVD loaded.

4) Wait for some time. If you see the installation screen, you are almost done. Go through the installation process.

Go to disk utility and create a partition if you can’t see installation disk.

5) I got the following warning message at end of the installation. It’s not an issue, just restart the Virtual machine.

Note – Shutdown and Restart will not happen normally, you have to do it manually from VirtualBox console. You have to load empireEFI ISO again to load from installed hard disk.

6) This time, select mac hard disk by right arrow key and press Enter to boot. I’m sure after several initial configurations you will land on Snow Leopard desktop successfully.

Let’s Check and Fix Some Issues in Snow Leopard in Oracle VirtualBox 3.2

1) Network worked out of the box. NAT and Bridged type worked without any patches.

install Snow Leopard on VirtualBox 3.2

2) 10.6.3 Update in VirtualBox Mac OS X Guest Yes, it worked. I downloaded combo update and successfully updated.
updated- 10.6.4 update also worked nicely with this method.

install Snow Leopard on VirtualBox 3.2

3) USB Support It worked well. Somehow data transfer is a little slow but manageable.  It detected my USB hard disk and flash drive.


4) The sound in Mac OS X Guest Sound is a little issue here but worked. I’m sure you are not going to connect 5.1 speakers, watch movies and listen to songs. So follow these steps to install Sound drivers. For me it worked, one side speaker worked with little distraction.  Something is better than nothing.

install Mac Snow Leopard 10.6.3 in Oracle VirtualBox 3.2

Updated- Try this driver for easy installation through pkg file.

If you are not happy with it then try manual method.

Download this driver file; extract the AppleAC97Audio.kext file on Snow Leopard desktop.

Open Terminal, (/applications/utilities/terminal.app) Type sudo -s in terminal then your admin password following this, now you should be root.


 sudo mv /users/(YOUR USERNAME)/desktop/AppleAC97Audio.kext /system/library/extensions

At this point, the file AppleAC97Audio.kext should have disappeared from the desktop.


sudo chmod -R 755 /System/Library/Extensions/AppleAC97Audio.kext


sudo chown -R root:wheel /System/Library/Extensions/AppleAC97Audio.kext

Now, CLOSE TERMINAL, then go to /system/library/caches/com.apple.kext.caches/ and trash Extensions.mkext (This cache will regenerate automatically on boot with the current kext library) Reboot and enjoy sound support! Original Source is here.

5) Screen Resolution and Screen Size Follow the steps to adjust the screen size. Widescreen size didn’t work for some users.

6) Shutdown and Restart We can’t shut down or restart Mac VM normally. You may see messages showing ‘CPU halted’ (for Shutdown) or ‘MACH Reboot’ (for restart), this means nothing will happen after it. Power off or reset virtual machine from VirtualBox console. Here is the working Snow Leopard Guest on VirtualBox 3.2.


7) Update 1

Install Boot Loader permanently and some fixes

To avoid attaching empireEFI ISO every time and boot OS X virtual machine, you can install bootloader permanently on mac local hard disk. This method will install Chameleon bootloader, and some other drivers and fixes.

Go to Empire EFI CD, which already mounted an open Post Installation folder. Take a snapshot before doing anything at this point. Run myHack Installer Package.

Select Customize in Installation Type. install Mac Snow Leopard 10.6.3 in Oracle VirtualBox 3.2

Read each package description and select if it requires for your hardware. I recommend to not deselecting anything, which selected by default. Press the Install button to continue. install Mac Snow Leopard 10.6.3 in Oracle VirtualBox 3.2

After successful installation, remove empireEFI ISO. Start the virtual machine, it should boot from the hard disk as shown below. install Mac Snow Leopard 10.6.3 in Oracle VirtualBox 3.2

If this doesn’t work, restore VM to the last snapshot and install Chameleon bootloader from separate installation file in Post Installation folder. After this installation, bootloader worked and I can see good performance in OS X virtual machine on my Intel Core2Duo PC.

8.) Update 2

Some fixes for booting issues

a) Mac DVD reading error EBIOS read error: Error 0×0c Block 0×1ed48a Sectors 0 This is due to accessing data from Mac retail DVD to VB. Convert DVD with some cloning software to ISO. More people faced the same issue and solutions are suggested here.

b) Booting errors after installation. Try with verbose or Boot Ignore Caches. In empireEFI bootloader, go to mac disk by pressing the right arrow key. Once it’s selected, press down arrow key that will bring more options. Select and press Enter. install Mac Snow Leopard 10.6.3 in Oracle VirtualBox 3.2

c) Change Boot Loader For old type processors, select legacyempire_efi1085.iso, which will be in the same folder.

if this bootloader and method don’t work on Intel processor then try this method with different iboot loader.

9) Shared folder between mac guest and Windows host, read this post ( Point 3) Network required.

10) Update 3 ( 17-02-2011)

  • USB disks access gives trouble with the same guide in Oracle VirtualBox 4. Snow Leopard virtual machine crashes when trying to explore USB storages such as flash disk and external hard disk.  If you face the same problem, then check this guide on how to fix this issue.
  • IOUSBFamily.kext and IOUSBMassStorageClass.kext files should be replaced to older version immediately after the software or manual update to 10.6.5 or 10.6.6 before the restart. If not, USB mouse, keyword, USB storage devices may stop working after the update.  Read this guide on fixing USB issues after the update.


Again, this method is just for learning and testing purpose. Feel free to share your comments and issues you face. I’m not a Mac or VB expert, but I will try my best to help you.

Have Fun.

  4. Man, you are a genius, thank you for this, i wanted to try this for a long time but now i have a chance to do so, and i did it so THANK you once more.

  5. Hi,

    I appreciate the help given. After burning a few hours on installation and almost giving up I finally got this installed. One tip I would like to offer others running this in a Virtual Box, I’m running VB 4.1.8 is to clone the the Virtual Disc. If you right click on the machine you are offered an option to clone. I tried to update to 10.6.8 and was stuck with a machine that no longer had a mouse. I just opened the original machine and followed the proceedures on http://www.tonymacx86.com to a tee and was updated

    Thanks again for the help. Now on to installing Lion. .

  6. All Hail Dinesh!
    I have tried all day with different peoples solutions to this. Yours works. Thankyou very very much. Well done mate. Great stuff!!!

  7. This did not work for me the EFI boot strapper started but it will not boot from Snow leopard disk
    Please advise?

  8. Hi Sas,
    I didn’t have any luck using the cd. You need to convert it into an image file *.iso. You can use imgBurn for that. Google it and download it. I actually copied the contents of the cd to a folder on my desktop and created an iso from that.
    Hope that helps.

  9. Hi, I have just intsallted virtual box , but my windows window is very small and i cannot get it bigger. Has anyone here an idea what to try?

  10. Hi,

    I tried to install Snow Leopard using your guidance but I’m having trouble on step three. The EFI loads perfectly but when I change to the OSX userdvd iso, it starts writing some stuff, but after a few lines Virtualbox crashes. I’m running version 4.1.8 on windows 7.
    I also tried the snow leopard made by hazard and also crashes! I don’t know what to do!

    My computer is a Sony Vaio, Intel Core Duo 2.00 GHz x86. I have 2.00 GB RAM.
    I have hardware virtualization enabled.


  11. I am trying to install on Intel Core Duo 2.6GHz x64 + 4GB RAM. I have virtualization enabled and am running 2 Linux flavors on my VirtualBox. I came across this post and trying to install the Mac OS X 10.6 Snow Leopard on my VirtualBox. I was able to boot using boot loader and start the installation. However after accepting T&A, it asks for selecting a drive I want to install & that screen does not give any options. I have created new .vdi files twice one with 80GB and another with 100GB but both are not showing up under “Select the disk where you want to install the Mac OS X”. Any help is appreciated.


    • Thanks for the quick reply. Sorry for the novice question but I am not sure how to do disk partition on the Virtual Drive (.vdi). I know how to do it on physical machine but never did on virtual machine. This is a fresh .vdi I created from Mac OS.

    • I think I found the place to do that. It was under utilities of install screen. I did work with Mac OS before but never installed the OS so this is my first time installing OS. Thanks for the pointer though. Appreciate it.

  12. Issue: I got the sound working. I installed the flash player. When I go to youtube and play a video, I can hear the sound but video does not play. In Safari it is black and I can see the play / pause button, and in Firefox it is just white box without any buttons and I can hear the sound but no video there either. Anyone faced this problem? Any idea how can I get that working?

  13. I have a message “memory allocation error (0 * daa26a0, 0 * 20 498)”
    Who can help me?
    Thank you in advance.

  14. Does anyone know about updating the operating system. I installed snow leopard 10.6.3 but need 10.6.6. I downloaded the update. It ran through the process up until it states you need to restart your computer. at this point I am running Chameleon and not empireEFI ISO. What would the next step be? Obviously if I save it I will be brought back to the screen “you need to restart your computer”. Do I perform a manual shutdown and close without saving?
    Any help would be appreciated

  15. Hi,
    I have installed OSX on a virtual machine (virtualbox) but quartz extreme is not being recognized! I however believe my graphic card is able to support it. It is a nvidia geforce GT 540M. I had a look on the nvidia site but have not found any info on whether my graphic card supports it… Could somebody give me a link to help find out?
    I therefore think the problem comes from the virtual box! Is there a way (wathever solution) to make it work on a virtual box? It seems impossible to make iMovie work without quartz extreme… 🙁
    Otherwise, is there an app that woul simulate or force its recognition or its processing?
    Thanks in advance

  16. I tried this and I get to where I’ve entered my OS X disc and then it tells me that VM has encounted a serious error and it closes and says look at logs.

    They don’t seem to tell me much

    • That’s nothing much. all you have to do is restart the machine. If that doesn’t work, try to free up RAM. BTW, I’m 11. lol.

  17. Thank you SOOOOOO much!!!! I have been getting that BIOS read error forever!!!!!!! It’s making an ISO now!!

  18. i have a question about the usb detection (flashdisk/harddisk)
    can you transfer (read & write) any data from mac to flashdisk? mine can’t, it’s just read only, so i can’t transfer anything to flashdisk, any ideas? thanks

  19. I got a kernel panic just after the apple logo appears. I’m not sure what I did but it eventually worked, I just fiddled around with settings. Was it removing support for floppy devices, allocating more video memory or disabling APIC I don’t know but it eventually booted 🙂
