Home Folder Name Change
My sister just gave me her MacBook, but I want to change the home folder name. How do I do this?

Here are the instructions from Apple on changing user short name or home directory name. I've used this on a couple of used MacBooks I've bought on eBay. And remember to go into System Preferences>Sharing and change the Computer Name in there.
