More and more frequently I find myself assisting customers with business analysis issues in Mac shops. Things can get complicated when dealing with multiple operating system platforms. A process that works great on Windows may not necessarily work on a Mac and vice versa. Throw some Unix or Linux into the mix and things get ubercomplex very quickly. To solve problems in heterogeneous computing environments, I like to have a test system with each operating system flavor at my fingertips. VirtualBox is the tool of choice for me. It’s free and offers a fairly low footprint on my computer. This tutorial will teach you how to install OS X 10.6 (Snow Leopard) on VirtualBox. I know there are a lot of guides on this already, but I found none of them detailed enough and most just didn’t work for me.
[step 1] Download and install Oracle VM VirtualBox.
[step 2] Visit http://www.tonymacx86.com/ and register a new account. Then download the iBoot.iso file here: http://www.tonymacx86.com/GYAdrDe6P1cZdIbL/iBoot-3.3.0.zip. Extract the ISO file and note its location, you’ll need it later. Download iBoot.iso here.
[step 3] Insert your Mac OS X Snow Leopard installation DVD into your computers DVD drive. Then open ImgBurn and create an ISO image file of the installation DVD. Note the location of this ISO file, you’ll need it later.
[step 4] Open Oracle VM VirtualBox and create a new Virtual Machine. For the OS Type Operating System and Version options, select MacOS X and MacOS X Server respectively.
[step 5] Next specify the maximum amount of ram you have available for the Virtual Machine (VM). My host system has 8GB of ram, so I selected between 2 and 4GB or RAM for my VM.
[step 6] Next create a new Virtual Disk (VD) in VDI format. If you select the Dynamic Allocation option, you’ll be specifying the maximum size of your virtual disk in this dialog. The disk file will only be as large as the aggregate of the data you store in your virtual machine.
[step 7] Once your VM has been created in VirtualBox, edit its settings by right clicking it. In the System->Motherboard tab, you’ll want to make sure that the following options are set:
On the System->Processor tab, select the number of processors you want your VM to have (my host system has a Core I3 processor so I selected two).
On the Storage tab, you may want to create two IDE CD/DVD drives. One should be the IDE Primary Master and one should be the IDE Primary Slave. This is optional, but you will always require one drive to have the iBoot.iso file mounted on it so I suggest having two virtual drives for mounting of other ISO files when needed.
Important: Select the IDE Primary Master drive, click the CD Icon and select Choose CD/DVD Disk file... and select the iBoot.iso file we extracted in [step 2].
There is no need to modify any other VM Settings, so click OK when done.
[step 8] Start the VM. After a few moments of running you should see the following screen:
[Step 9] Now we will need to virtually swap the iBoot ISO image for the the OS X Snow Leopard ISO image we created in [step 3]. Here’s how to do this:
[step 10] Follow the steps shown below in the guided OS X Installer:
NOTE: Some readers have reported a install screen without any installation destinations available at this stage. If this happens to you, it means that we’ll need to format your VDI or virtual disk as Mac OS Extended before you can proceed. Here’s how:
[step 10 a] From the installer menu select Utilities->Disk Utility.
[step 10 b] Select the virtual disk and then click Erase. Select the Mac Os Extended (Journaled) format and continue.
[step 10 c] When the format is complete, you should be able to proceed with the installation to the disk you formatted.
Click the available formatted disk to proceed with the installation.
[step 11] At the conclusion of the OS X installation program, you’ll be asked to turn off your PC. You’ll most likely see the screen below. When you do, close the virtual machine window and then select “Power Off the machine“. Note you can also do this from the VirtualBox management console by right-clicking the running machine and selecting Close->Power Off.
[step 12] Before you start your Virtual Machine again, we’ll need to make sure that the iBoot.iso file is set back as your default CD image. You can do this by editing your Virtual Machine Properties and checking to make sure the iBoot.iso file is mounted as the CD device.
[step 13] Now that your iBoot.iso file is mounted, we can start the Virtual Machine back up. After initial boot we should see the screen below. We can now use the right/left arrow keys to highlight virtual disk containing our OS X installation. Hit enter to boot the system. NOTE: whenever you change the CD device during a session, you must remember to change it back to iBoot.iso before restarting the VM. This is why I recommend creating to CD Devices. One as your primary containing the IBoot.iso image and one that you can use to mount other CD iso images.
Once your system boots, you’ll be asked to complete the setup program and specify personal information.
Once completed, your Mac OS X Snow Leopard VM should be ready for use. I suggest not installing the Oracle VM VirtualBox additions since they fail during the install on my version and there is an entire forum dedicated to hackery to get these to work. Sound isn’t perfect, but the VM works well enough for testing.
