Chief Issues with Mac and Parallel Rendering

[classicdesigns]

I am currenlty working with a builder that is having issues with rendering using parallel. The Mac Laptop has 6 Gig of memory and 1 Gig video.
Was wondering if anyone that has Mac Laptop and is currently working in x5 and has parallel if they had issues with rendering. Not sure if this has to do with how his hard drive is petition so it works on a PC side and Mac side. The rendering would go to a black screen and run slow. I don't think Chief likes parallel? I have no issues with Chief using my PC and runs great with renderings. If you do have a Mac and have not any issues please let me know how your system is set up.
