Non-compatible cycles g-card

Well, it seems that something (I’m guessing the graphics card) is not compatible with cycles. I’m running on a mac and have tried several different builds including cuda and non cuda but they don’t seem to work. I just get black in the window when I put the display to rendered. I’ve tried using it on a different mac and it worked. I don’t know what’s going on. Using an NVIDIA GeForce 9400m.

Pull down the top toolbar and check the error messages. Your card supports CUDA, and every CPU supports Cycles. You’re probably just missing some dependencies.

Make sure that you have the proper drivers (>= 270.61)

Or you don’t have any lights in your scenes ;). Make sure that you have “use nodes” checked in the world settings in case there are no other light emitting objects.
