It works and it works very well indeed. That MacBook renders so fast that even though it needs to send the data back to my computer it delivers almost at the same pace then my G4. Apple really pulled this one off. They are completely compatible. Probably Eovia had started in the port to UB because I bet it was not easy to recompile all that code. I don't think the Carrara team had time after moving to Daz to pull this off. This is very good news for Mac users like my self that are in-between processors at the moment. Now I have 4 processors for rendering. Yeah!!
