So I'm working with a Macbook Pro Retina Mid 2012, I just bought it,
Processor 2.6 GHz Intel Core i7
Memory 16 GB 1600 MHz DDR3
Graphics NVIDIA GeForce GT 650M 1024 MB
Software OS X 10.8.2
Installed the most up to date CUDA Mac Driver: CUDA 5.0.37 driver for MAC
After Effects was running fine -no errors at startup - when I didn't have the GPU CUDA enabled.
I found out that the NVIDIA GeForce GT 650M 1024 MB, is CUDA Enabled
So, I installed the CUDA 5.0.37 driver for MAC
I opened Terminal and ran a GPUSniffer to get the name of the Graphics card
I opened another window in terminal and ran a "sudo nano" command that listed the default supported Cards, I pasted my card name.
NOW I can choose GPU instead of CPU for Ray-tracing, WHICH IS GOOD, Its what I was trying to do. BUT something is still wrong because I keep getting an error message at startup: "After Effects error: Ray-traced 3D: Initial shader compile failed. (5070 :: 0)"
I DIDNT GET THIS ERROR BEFORE I INSTALLED & ENABLED "CUDA GPU"..............What is wrong?
Don't manually manipulate that text file. That is unsupported, and you are on your own if you do so.
What you should have done is to install the 11.0.2 update to add the GPU acceleration of the ray-traced 3D renderer for your 650M:
Thanks so much! Everything's working great now.
