Hi, i'm new to OS X as i received my new aluminum MacBook less than a week ago, and am so far loving it. Although, i need some help. I'm needing to take some photos with a webcam as I have no other cameras and cannot use the iSight to take the photos that I want. I have tried plugging in my webcam which i know is compatible with OS X but, i can't seem to get PhotoBooth to use it. Help would be appreciated Oh, and another thing, i've noticed that when i'm moving my macbook around (if i'm carrying it) sometimes i hear a distinct click. Should i be worried? Is this normal?
