Emulate a Mac on Windows

"There are projects to run the Mac OS on a PC, this is sometimes called a ""Hackintosh"". You're not going to find official support from Apple on this, though, and you'll have to be comfortable with breaking the OSX license, which I believe only licenses the software on official Apple hardware.

But yes, it can be done, for the whole system.

However, to specifically answer your question, there's no way to run one single program from a Mac environment in a windows environment."

"You cannot legally virtualise Mac OS X client. From Snow Leopard's EULA:

Subject to the terms and conditions of this License, unless you have purchased a Family Pack or Upgrade license for the Apple Software, you are granted a limited non-exclusive license to install, use and run one (1) copy of the Apple Software on a single Apple-branded computer at a time. You agree not to install, use or run the Apple Software on any non-Apple-branded computer, or to enable others to do so.

You can, however, legally virtualise Mac OS X server, but only on Apple hardware.

This License allows you to install and use one copy of the Mac OS X Server software (the ""Mac OS X Server Software"") on a single Apple-labeled computer. You may also install and use other copies of Mac OS X Server Software on the same Apple-labeled computer, provided that you acquire an individual and valid license from Apple for each of these other copies of Mac OS X Server Software.

That's not to say you can't do it illegally, I've seen many torrent images that include a ""tweaked"" Mac OS X VMware image and the VMware Player."
