My guess would be that if Cinema 4D works on osX that the plug-in would to. Maybe you should contact Curios Labs and ask them, if therir still working on the plug-in maybe they can work it in. Or maybe that's way it isn't out for the mac yet. I have osX and loved it but I put away until Illustrator and photoshop are upgraded for it's use. I still have to many programs that aren't ready for it to make it of any value other than the interface enhancements.
