I'm looking to move back from Maya to C4D. I just tried using Prorender by selecting it. As soon as I did that, C4D crashed.
Is this due to the trial version? Maybe a hardware limitation? I have a 2013 MacBook pro with an NVIDIA card in it, and also need this to run on a 2010 Mac Pro desktop
Pro render is a GPU rendering engine so you must have with you a specific graphic card such as ATI Fire or Radeon Pro on some mac books.
I think you need to move on a CPU rendering engine instead of GPU rendering engine. If you want to move on a CPU rendering engine for your macbook or mac pro desktop try Corona Renderer
