I've just started all this. I've joined the MR team with the same username I have here. That's all honky dory. But- I cannot get my PowerBook or the OSX side of my C2D iMac to work. The PowerBook just doesn't progress past "Completed 0 out of 5000000 steps", and the intel build for my iMac just doesn't work, the graphic is broke. I suspect that isn't folding either. However the Windows XP side works like a charm. Though it's only using 50% of my CPU. Does this mean it's only using 1 core? How do I get it using 2? At the moment it's taking about 12 hours or so to do 1 WU. With my PowerBook and the other core kicking in I could rack up some better figures So let me end this with a cry for "help!", thank you!
