This is optional, but I think it helps to improve the stability and usablity of the USB support when you install Mac OS X in Virtualbox I don’t think I need to elaborate on how to do this? Download the Virtualbox Extension pack and install as well. Download the iboot software from tonymac forums.ģ. I don’t think it is appropriate for me to reveal openly where to get a copy. Download or get a copy of the Mac OS X Snow Leopard installation CD.
