So, my iBook (along with just about everything else of value that I own) was stolen off a bench in a hallway on Wednesday when I went into the next room for five minutes to help a friend with something. I am close to panicking. The police told me to call them with the computer's serial number if I can figure it out. I know I had to type it in when I registered the computer - is there any way to retrieve it? It was a 14" iBook G4. I am at a complete loss for what to do.
