Retail Snow Leopard Mac Os X as Guest on Oracle VirtualBox 4

Latest versions of Oracle VirtualBox allows you to install and run Mac Os X 10.6 out of the box (just one little trick needed). You need a VT-x enabled CPU.

• Install Oracle VBox
• Create a VM (Mac Os X / Mac Os X Server)
• Allocate a Fixed Size Hard Drive (20GB is enough)
• In the machine properties set 128MB to Video System
• Leave all as default (Make sure EFI is enabled)
• Go to your VirtualBox Machine description file (vbox extension) and add those lines in the right position in the XML tree

• Install Mac Os X from an original copy you can buy in an Apple Store
• You couldn't install Mac Os X on a Virtual Machine because its licence doesn't allow you to do that.
• Enjoy
