Is it really a lot to ask Apple for a Macintosh OS X virtual machine? I came across this article in ars technica that Parallels said it's possible to put OS X on a virtual machine but currently they won't do it as Apple's EULA forbids it. On top of that Apple is known for being fickle with it's vendors and Parallel's doesn't want to piss them off. I can't say I blame them.
I've got a Mac Mini that I don't use much and honestly I got it for the OS - the cool little hardware, that I've since put Vista on, was just an added bonus. I've got the OS discs, I've got VMware Workstation and I think it's time to figure out a way to install one on the other. I'll let everyone know how it goes!

The inner workings of getting Mac OS X to run on a virtual machine are incredibly complex as I found on OSX86Project.com.
I continued my pursuit and I came across a torrent on The Pirate Bay where someone managed to install and get working a Mac OS X virtual machine for VMware. I downloaded it, unpacked it, ran it and found a real working version, albeit a bit slow and clumsy. The boot times and regular operation were slow, it didn't have all of the beautiful graphics / effects of the normal version and well was barely usable - other than perhaps for the occasion test.
This Virtual Machine version of Mac OS X will work if you don't have a Mac computer to play with, but I do, so this program will officially go into storage. (I don't want to get rid of it.. just in case...)
