Just a tip: if you do have to go the Single User route, the instructions there
are incomplete:
• Reboot into Single User mode by restarting the Mac and holding
Command-S while the system comes back up. Numerous lines of status messages
will scroll by.
• Once you have a command-line prompt, enter this command to mount the
root Mac OS X drive as writable, so you can make changes to the filesystem:
mount -uw /
You really want to do a ‘fsck -fy' command first. Fortunately OS X tells you
that when you boot into single user mode.

I repeat the fsck command until it reports that no changes were made to the
file system before I mount the volume for read/write access. 99.999% of the
time this means running it only once or twice. If it comes up reporting errors
on the second run, there’s likely something wrong with the disk.
Navigating single user mode is a useful tool; you can use it to ‘break into’ a
Mac you don’t have a password for, just do the above, then delete the file
/var/db/.AppleSetupDone and reboot. The Mac now thinks that it’s never been set
up and walks you through creating an admin account. All the other users,
applications, setup, etc are retained.
I do this with new laptops where I work: I set up the mac with our standard IT
support local account, install all the required apps, printers, VPN, etc, then
delete that file and hand it to the end user. They can set up the account name
they want and password, so we never have to write those down ;-)
