Replying to Music Producing on Macs

I got my macbook pro about 2 weeks ago now and I absolutely love it. I'm going to school for music production and performance so I was just wondering if anyone here is in the same boat. Right now I'm cheap and recording on garage band until i save up for Pro Tools and all that goodness. I'm still tweaking with a bunch of things on the computer, so if anyone has any cool tips for anything music I'm down for some advice. cheers
