I need some guidance. I am new to Mac and am trying to learn how to use the Final Cut Pro 5 suite. The thing right now that I need help with is optimizing my system so that it runs faster. Just the other day I was using Motion and I checked out how much RAM I was using and I was only using 456Mb out of a 1Gb of RAM! I didnt understand why. And then just before writing this while Im not really doing anything but surf the web a little and it says I am using 585Mb and that 300Mb are inactive, 23MB are free, and 115Mb are wired. How do I get my computer to use the entire RAM when it should?
