Black window with Torque 1.5 on Intel Mac

I released a game developed with Torque v1.5 for Mac and PC. I have one user who installed the game on an Intel Mac, and is only getting a black window. I asked him to try the original Torque FPS Demo, and he had the same result.

Here is a description of his system:
quad-CPU Intel Mac running OS X 10.4.9 with 3 Gb of RAM
I get a menu bar with "Torque Demo OSX" and a completely black window.

Below is his console log. Any thoughts?
