Is there a way to change a short name in OS X I am trying change the Short Name for an account on my computer. Is there an easy way to do this?
Use these steps to change the short username of an account on your computer:


Open System Preferences
Choose the "Users &amp; Groups" preference pane
If the padlock at the bottom left is locked, click on it to unlock it with an administrator password
Control-click on the account in the users list
A menu will appear with "Advanced Options…". Select that and you will get a sheet where you can change the account name.
