I just got my new Macbook. Been installing stuff on it and it seems to go reaaaaaally slow. I installed quicksilver and whenever I pull it up and start typing it'll be really slow and show the rainbow wheel and won't respond for a few seconds. It's always pretty quick on my ibook. Also, after moving stuff to application, the entire system freezes for a 15-30 seconds. My iBook seems a lot faster with all these problems. What the heck is going on?
