This may sound really stupid, but this is my first Mac! I've had it for a couple of months and there's a couple of things that have been bugging me. Is it possible for me to safely change the name of the Macintosh HD icon on my desktop via the Get Info pop up? Also, how could I change the icon of the HD, to say a black MacBook. Would these changes be shown when i'm installing a program and it shows the different volumes on the Mac? How could I make it so all icons are on the left of my desktop automatically? So when I start downloading something, it defaults to putting the file icons on the left?
