Hi, I have a MacBook 5,1 running Lion which was gifted to me in 2009. They had already set up the user account for me, but accidentally misspelt my name. I have been using it like that till now. So is there a way to change it without losing my settings/preferences/keychain items/iPhoto Library/emails? I have enabled File Vault and it is the only account on my system. And I am talking about the user name (not the computer name), i.e. the name of my home directory and the output of "whoami". There are also some files in my home directory that have read/write permissions for only this account/user.
