There are lots of ways you can transfer files between Macs, and one of these is to use FTP. This method of file transfer can be practical if you have a lot of files to copy, and you want to manage how many get sent at a time.
Turning on FTP in OS X is quite simple, but it’s not easy to find. Go to the Sharing pane in System Preferences, and then enable Remote Login.
This enables both FTP (or, more accurately, SFTP, or secure FTP), and SSH (secure shell). You can then use your favorite FTP client to copy files to and from that Mac.
