TouchDesigner not opening on my Mac tower

I can’t seem to launch the application, I just get a black screen with a few letters in a dialog box. Is this computer not supported? I’m running OSX 10.11.6 on Mac Pro (2008) with NVIDA GeForce 8800 GT.

I suspect your graphics card may be a bit too old to run our software. You can find our system requirements here
