MAC Alias Automotive Render & Direct Render Fails?

Hi there guys,

I just bought a Macbook Pro Retina maxxed and also my renders seem to fail!
I notice it happens when i put in some wood textures, which leads me to believe texturing might be the problem here.

Do you guys know a way around this? I have no Windows version of this, so i really need to find my solution here!
Thanks
