I have a Mac Mini that keeps going to sleep on its own. This seems to happen with processor-intensive functions. Someone suggested the heat sink on the processor wasn't installed correctly (I just had this unit fixed about 3 months ago). The place that fixed it says the motherboard is bad. Whatever. At this point I'm hoping there is a way to disable the sleep function all together. I rather doubt the thing will burn up and even if it does, I'll have to buy a new one anyway as a new motherboad costs more than a new machine. Can any of you UNIX experts help me out with the command?
