Hello everyone. This is the first time I've clicked on this section of the forums because now I actually own a Mac! Yes I know, I'm excited and that's kind of weird, but you've no idea how long I saved up for that day to come when I could own a Mac. Anyway, I've seen people hover the mouse over the icons on the dock and the icons seem to enlarge as the mouse scrolls over them. How do you do that? Mine doesn't do that. Also, are there any good programs out there to customize my Macbook? For example, changing the sound effects, screen savers, any other cool apps? I know, I'm a total Mac newb, but hey we all start somewhere.
