ZDOne writes "ZDNet's reviews team have been tinkering with the various ways of running OS X on standard PCs. They found that with the right hardware components, a standard PC running Mac OS X Leopard is, at first sight, no different from a genuine Apple Mac. Special CPU extensions such as Intel VT-x provide support for software solutions like Parallels Desktop for Mac. Even Adobe Photoshop, which queries a Mac to verify its authenticity, runs fine on a standard PC thanks to EFI emulation. However the article points out that it's a pretty technical proposition to get OS X running on non-Apple hardware, beyond all but the most powerful power users. And then there is the legal question. Don't even think about trying to put OS X on your PC without first purchasing a legitimate copy of Mac OS Leopard."
