How to change short name on Mavericks?
My OS X user account has an invalid shortname. Short names can only contain lowercase letters and an invalid shortname can cause many different problems for some apps.
Apple has a technote about how to change the shortname , but it is not working on my Mavericks.
Any help will be appreciated.
