OSX Command Line Password Changing

A simple way to change the password of a user is to boot into single user mode in the mac.  This requires a cmd-s upon startup.  This will launch the command line.

In earlier versions you then mount the root filesystem read/write

-> mount -uw /

Then change the password.

-> passwd username

In later versions of OS X you mount the filesystem read/write then

-> launchctl load /System/Library/LaunchDaemons/com.apple.opendirectoryd.plist

-> passwd username

Exit and you are done.
