Well due to the way apple is handling no portability to 64 bit its not likely to see a 64 bit version on mac for a while. So thi sis truly apples own fault. I mean both autodesk, and adobe had a 64 bit version but apple axed the support for such things off.
This is what you get when you go extremely proprietary. Apple can screw you over whan they wish so.
I mean andersen lcc says it all on this page

thats a problem assiciated with the limitted set of mac grfx cards.
The bottom line is mac is just not very good for other than just the bare bone basics. Unfortunately so, because on the basics mac shines off. But if you compare a highend pc with ahighend mac you can actually see why.
