When I export a file from iMovie, it usually takes a long time but uses a lot of CPU, and my computer gets very hot(around 180-190ºF), even with my fan controller maxing it out. Would I be able to slow this down so that it wouldn't put as much load on my computer? Or really for any app where it might be doing some intensive thing in the background. I get a little nervous having it working so hard for such a long period of time. I was hoping there would be some terminal command or other local way to do this, Thanks.
