2.
Click the Show All button in System Preferences, and then click the
Sharing tab. Check File Sharing.

There's no need to select a folder to share because, by default, those log-
ging in with the username and password of an account get access to that
user's home directory automatically.
4.
When done, close System Preferences.
5.
On the remote Mac, you'll need to repeat step 1 to enable Back To My
Mac, but there's no need to repeat steps 2 and 3 to enable File Sharing.
Once you've enabled Back To My Mac on the remote Mac, the home Mac will
appear in the Finder sidebar under the Shared heading, where you can click
it to automatically log in and access its files. Remember that in all likelihood
file transfer will be pretty slow!
When you've finished transferring files, click the Eject button alongside the
computer's entry.
Sharing Files Using SSH
OS X features SSH, software that allows command-line logins from remote
computers across a network or the Internet. A component of this software is
SFTP, which is essentially a secure version of File Transfer Protocol (FTP),
which you might have encountered if you've ever created a website. SFTP lets
you retrieve and transfer files from a computer without the risk of snoops
(although on your Mac it is supported only at the command line and not via
Finder).
SSH can be enabled by starting System Preferences (Apple menu→System
Preferences) and then opening the Sharing pane. Check the Remote Login
box in the list on the left. On the right you can allow either all of the users
on the system to log in remotely or just some (although this is moot if you're
the only user of your system).
You can use SFTP from the command line of another computer if it has the
correct software, but most graphical FTP clients include SFTP support.
Remember that you'll also need to ensure your Internet router hardware
allows SFTP connections. This can be done within its configuration panels.
There is no need to deactivate or alter any setting of the OS X firewall—it is
automatically opened to allow incoming SSH/SFTP connections.
