Maya 7 Rendering On Mac Problems

Hey All,

I'm running a quad proc 6 gig of ram Mac with Maya 7. When I render either a batch or quick render the computer is only using anywhere from 30 to 50% of the proc power. I have tried both MR and MS neither of them will use all 4 procs to render.

I have tried using "use all procs" and also just typing in 4 in the batch render options. I am moving over form a PC and I never had these problems.

Can somebody please tell me how to fix this problem. its driving me nuts.

thanks for the Help
