I am wondering what you guys are using in order to have Blender`s new render engine "Cycles" recognize your GPU instead of your CPU. I have a 2011 macbook pro and a 1,1 Macpro with a flashed 1 gig HD 4870 but neither are supported in Cycles. Are any Macs able to support this type of rendering with apple being of the opinion that graphics cards are not important. It is so much faster when rendered through the GPU and I would love to be able to do this. Any suggestions? Thanks
