Boot to single-user mode (hold command and the S key for 45 seconds at startup).

Type:

/sbin/mount -uw /

Press Return.

{Nothing appears to happen, no problem.}

Type:

cd /users

Press Return.

Type:

ls

Press Return.

{You see the user account folder names -- "Shared" plus any that were created. Write down any that were created.}

Type:

rm /var/db/.applesetupdone

Press Return.

Type:

reboot

Press Return.

{Now stuff appears to happen.}

Setup Assistant appears. Create a new account, but be sure to choose a different short name than that of the original [[short name is the name of the user account folder that you wrote down]].
