Hello, just got my first Apple computer last Friday and so far so good for a PC ex-owner for 20 years. During the original setup of my Mac Book Pro, without thinking about what it would do, I used my full legal name to "name" my computer. I noticed somewhere yesterday while looking through the computer a statement similar to this: Everyone will know your computer as "Billy's Mac book Pro." (paraphrased I'm sure.) I never use my first name unless required to do so on a legal document signature etc. Is there any way to change that to my middle name that I use all the time and the one everyone knows me by? This forum has already been a tremendous help to me and I hope to be able to add to the discussion soon.
