Quote - There are some stand alone products specifically written to work under Windows, and some Poser Python script products that were developed on PC and may need a different version, or some post-purchase adjustments, to work on a Mac. These products will usually be clearly marked on the product page as being for "PC Only" or "Windows Only".

I really wish these vendors would make their source code available. Due to the UNIX which runs underneath Mac's Aqua user interface, every Mac on the planet has the ability to compile the same utilities which Windows users take for granted. I wonder if these developers just aren't aware or if they just don't care.
