I've dl'ed hundreds of "PC Only" files (both commercial and free) for my Mac and been able to use every one after processing them with MacConverter and a little patience. That's a success rate of 100%. The one kind of "PC Only" download that won't work is applications which I knew in advance not to try. You'll be okay with any kind of pure data file (textures, characters, etc.) However, any kind of application that processes or creates this data (texture converters, morph managers, etc.) probably will not work on your machine. (The "probably not" is because Python scripts will usually work on PPP and up.) You did not say what you type of product you were considering, but if it's a some kind of data file you shouldn't hesitate because of the "PC Only" issue. As you see there's plenty of help available here if you should run into difficulty after purchase. T Jobe
