I know that Macintosh is planning on releasing their OS on PCs, but only ones that they make. I have heard that its possible to get mac os x on a normal x86 computer not made by mac. Is this illegal? If not, how would it be done?

Yes, the current x86 version of OSX floating around on the web is 100% illegal. I'd recommend not using it - also part of the 'Mac OSX' experience is not just using the OS but also from using it on Apple hardware - you would only get part of the experience on a normal x86 PC.

I'd advise against trying it - purely because its illegal.

yea good idea. Man, if i wern't a gamer, i'd own an Apple.

OSX for x86 is only designed for intel chipsets tho too. and all technicalities aside, when it is released it will be the same hardware. incase you haven't heard Apple is switched from IBM to Intel as their chip cores.

Right, but you still will only be able to buy compatible computers from apple.

no you won't. you can put it on any pc with an intel chipset.

Apple say that they'll only allow OS X to run on computers they make though. Yes, it would be possible to run it on a normal Intel system but its impossible at this stage to know how hard or easy this would be.
