If your running Mountain Lion you may have noticed the missing FTP sharing options. Don't worry, FTP server is still there, even if it is a client installation and not a Server install. You have to enable FTP server on a client install from Terminal

Lets get started

• Open up Terminal
• Copy and past the following command

sudo -s launchctl load -w /System/Library/LaunchDaemons/ftp.plist

To disable, do unload instead of load.

Note: The default FTP directory is the users's home directory.
