What type of machine is he using? Tell him to do the following:

1) Apple icon > About This Mac > More Info...
2) Under hardware, click on Graphics/Displays

If it lists the chipset model as anything with Intel in it's name; you will get this issue. I have the same problem on a MacBook with Maya 2010. I am looking into some possible fixes however. I'll let you know if I come across something that works.
