I need some guidance. I am basically new to Macs but my friend is about to buy her first computer EVER and she has decided to go with a Mac which I think is a great choice for a first computer. Anyways, since it is her first computer you can guess she is clueless as to what she needs. I am going to go shopping with her since I have at least bought a computer before. I need some advice for what I should be looking out for when it comes to buying a Mac laptop. Does the OS come with Macs when you buy them at the store? Are there some things that come with some models that I may not need that could save us money if we opt out? I just need some general info and advice, I'll even take suggestions on what to buy. Thanks in advance.
