Despite what the developer's site states, this WILL NOT install XP onto an Intel iMac. I took the voluminous amount of negative feedback here with a grain of salt, gave OpenOSX the benefit of the doubt, and ended up losing $25 for my efforts.

For a good laugh, check out the "Installation Instructions" on their site that uses screenshots from a different version than the one they're selling. Very professional...this developer's site should have a countdown clock representing the small amount of time left before he goes out of business.
