Hello, I recently got a black macbook and mighty mouse. This is my first mac and I love it. Its been the greatest computer i've ever had. I have been using this computer for browsing the web and listening to music. I currently have a nice set of speakers I have it hooked up to! Now i have a few questions. How can I maximize my use on the macbook. What are some cool things that i'm am clueless i can do on it. What are the greatest features. Which widgets should I download? Another thing. On the corner of my macbook. the corner to the left of the trackpad. on the left side there are two screws. If i push a little in between the screws it goes in a little and macs a little noise. Its not big deal at all i was just wondering if anyone else has noticed it and if it can be corrected by possibly tightening those screws up. Well thanks!
