I just upgraded my system from Mountain Lion to Mavericks. When my system restarted, the Setup Assistant ran.
The Setup Assistant is asking me to configure things on my system that are already configured — location, internet connection, etc. Plus, it is forcing me to create a new user account, but my user account from Mountain Lion still exists (evidenced by the fact that when I try to enter my previous user name, Setup Assistant informs me that username is taken and won't let me continue).
Seeing as how my system is already configured, I'd like to skip the Setup Assistant.
How do I do that?
