Go to Virtualbox website and download the installer for your OS. If you do not own a Snow Leopard disc, you might want to search for a OSX86 iso file and download it. Step 1: Open the VirtualBox software and click the “New” button. IBoot by tonymacx86 is a Chameleon Boot132 CD specifically designed to work with Intel CPUs. It enables a simple disc swap-out for the Mac OS X Retail DVD, and a vanilla installation. Added features for most motherboards include audio, network.
Open the VirtualBox software and click the “New” button. This will launch the ”create a new VM”.
Foreword: This was originally written in 2007 for VirtualBox 1.5.x
update: VirtualBox 3.2 supports Mac OS X guests out-of-the-box, without the hacks described here.
The problem needs to be devided into 2 aspects: political & technical.
Apple only allows their OS to run on Mac hardware. The only workaround I see here is to run VirtualBox on Mac hardware to virtualize Mac OS X. Or some big company (Innotek?/VMware?) needs convince Apple to license their OS in different way...
Since I'm not a politician, and not a lawyer, I'll let others to figure this out.
According to Alexander Graf: (http://alex.csgraf.de/self/?part/projec ... 20OSX/qemu)
While the EULA clearly states, that running Mac OS X only once and only on Apple hardware is allowed, this does not exclude running it legally in a virtual machine on Apple hardware. This is basically the same approach that Mac-on-Linux took, but this time with the Intel based version of Mac OS X.
Of course, as all the hardware Mac OS X runs on with this solution is virtual, the very same approach enables potential users to run it on non-Apple hardware as well, which is illegal though.
Technical problem: (for users)
It gets interesting... but there are some hacker's versions of Mac OS X flying around the 'net. This version doesn't require EFI and other Apple hardware, but works with normal PC hardware instead. One of the images is Deadmoo's OS X for VMware. (Tiger v10.4)
This vmdk works on VirtualBox with only one modification to the boot command: platform=x86pc
(this disables ACPI, because Mac OS X dislikes VirtualBox's ACPI implementation due to incompleteness).
To make change permanent just configure Mac OS X bootloader:
On VMware WS 6 it works (slowly) without any workarounds, but on VBox it is much faster.
Requirements: Intel SSE3 and VT capable CPU. (VT must be enabled in VBox). Theoretically this should work on AMD too, but not tested.
Verdict: it WORKS ! (with a workaround and not stable, but it WORKS !)
Tested on VBox 1.5.x on Intel Core 2 Quad Q6600 on Windows XP 32 host.
NOTE: It is not easy to make it work, so normal mortals should not even try.
WARNING: Currently only Deadmoo runs. iAtkos, Leo4All, Kalyway, and all other images will NOT run.
First I would like to see VirtualBox improve to the way, where it will run Mac OS X without problems, then hope until someone convinces Apple. Perhaps, from a political point of view it would be smarter to work with Darwin first.
Update: In may 2009 a new, hacked bootloader arrived, known as 'boot-132'. If anyone has experience using it, please let us know.
***For Developers only !!! (users must skip this)
Qemu team developed initial 'Intel Mac' hardware target patches for Qemu, that may be ported over here, if anyone is interested (and has the knowledge).
On 8.Jan.2008, Alexander Graf from Novell sent several patches to Qemu to enable real Mac OS X emulation, so the number of stupid workarounds will decrease dramatically.
Quoting from his email:
the following patchset enables qemu to run Mac OS X with disabled

an Intel Mac close enough. The following patches are included:
This is based on the DMI support by Ryan Harper. As it is currently

unclear, if this approach is taken or if the Bochsbios is going to be
patched, I would recommend to not apply this patch for now. I still
submit it for completeness and because I have touched parts of it.
This adds an HPET emulator device. It is not feature-complete but should
suffice for this purpose.
This adds a dummy LPC device the HPET is located on.
Apples binary protection sits in the fan control, which is the AppleSMC
chip. This emulates the devices and takes the protective key from the
Mac OS X as is has a condition to only run on family 13 Intel CPUs, so
this adds a definition for a CoreDuo CPU and an MSR as well as a CPUID
instruction that is required by Mac OS X
The oldest supported IDE controller in Mac OS X is the ICH6. This is an
incomplete implementation for that controller, that suffices for running
Mac OS X and worked with libata for me as well.
To leave the default behavior unchanged, this adds a 'mac' machine
definition that automatically chooses the right hardware for an emulated
To boot Mac OS X a mach bootloader has to be run. David Elliot modified
the original i386 Mac OS X BIOS based bootloader to emulate the EFI
entries and support multiboot, an easy but straight-forward kernel
loading interface founded by grub. To boot multiboot-compliant kernels
directly, this adds support for multiboot loading to the -kernel option.
Several ACPI entries were missing from the bios and the new controllers
need to be initialized properly.
This patch is against the bochsbios. Should this rather be sent to the

10. VirtualBox will also need to emulate a better Ethernet controller, such as RTL8139 (or at least default to Intel E1000 for Mac guests), because Mac OS X doesn't have AMD PCnet built-in drivers (alternatively the driver can be installed via 'Maxxsus 1.0 network patch' as GuestAdditions. The 'Maxxsus 1.0 network patch' is essentially AMD PCnet network driver for Mac OS X).
So this device also should be ported from Qemu.
With those patches ported from Qemu to VirtualBox it won't require hacker's Mac OS X anymore... it will work with standard Mac OS X from Apple. Normal users will be able to install Mac OS X.

If you need to test a software on Mac OSX, and it is not justifiable for you to get a new Macbook, a good way is to install the Mac OSX as a virtual machine in your Windows (or Linux) based PC. Both the two popular virtual machine software – Virtualbox and VMware, support Mac OSX installation as a virtual guest, but in this article, we will deal with Virtualbox.
You may be wondering why you should choose VirtualBox instead of using VMware. Well, for one reason – you will save yourself a good bit of cash, since VMware can costs you a pretty penny, and VirtualBox is a free solution. Of course, free is not enough to make a product worth your while. It needs to have other traits, such as stability and a development team that support it with regular updates. VirtualBox provides you with both of these things, so you can use it with confidence that you will not end up with problems a year down the line.
What Do You Need On Your System
In order for this system to work, you need to have a setup that has either an Intel
or AMD processor that is capable of supporting hardware virtualization.
What You Need to Do
First off, if you have not installed VirtualBox, now would be a really good time to get it. Go to Virtualbox website and download the installer for your OS. If you do not own a Snow Leopard disc, you might want to search for a OSX86 iso file and download it.
Step 1: Open the VirtualBox software and click the “New” button. This will launch the ”create a new VM” wizard tool which is designed to walk you through the setup.
Step 2: Give your new VM a name (I named it Mac OSX). Choose “Mac OS X” in the “Operating System” dropdown menu, and then select “Mac OS X Server” from Version dropdown menu, which you will find in the same area.
Step 3: Assign the amount of memory you want to allocate to the new operating system.
The maximum in VirtualBox is 1500MB, but you will want to temper this figure based on what you need to do with the system, how much memory you have in total on the system, and the types of programs you intend to install on under the new OS.
Update: The maximum in VirtualBox is not 1500MB. You can allocate up to 2GB if you have enough memory in your system.
Step 4: Make a new hard drive for your VM. If you are not sure how much you need, choose the “Dynamic” option. This will allow the system to expand as your needs do. If you choose the “Static” option, be sure that you know what you need and allot accordingly. Then click on “Next” to finish up with the wizard.
Step 5: Click on “Settings” and then “System”. Uncheck the box next to the words “Enable EFI (special OSes only)”.

Step 6: Choose “Storage” from the menu on the left and choose the word “Empty”, you will see it under the OSX.vdi. You will see a folder with a green arrow. Click on it and a new window will open. Click on the plus sign. You will now be able to find the OSX86 iso that you downloaded earlier in this process. Once you have highlighted it, click on the “Select” button and then click on “OK”. Finally, click on the main start button to begin the process.
Step 7: When all of this is done the VM should start booting. You will be asked to select a language. Do that and click on “Next” then “Continue and Agree”. The next screen will show you the words choose the 20GB VBOX HARDDISK, and click on the “Erase” button.

Step 8: Click on “Install” to begin your installation. When the installation is done click the Right-Ctrl key and unmount the CD/DVD drive for now. Then restart the VM. OSX should begin to boot.
There you have it Mac OS X Snow Leopard running in VirtualBox on your Windows-based machine.
