Instead of using CODA or any third party software, you can use MAC’s built in Terminal to connect to your website, as long as you have SSH access.
it will then ask for a password, enter your password (usually the same as FTP).
if you need to specify a different port other than the default port, type the following instead:
ssh -p 1234 firstname.lastname@example.org
(where 1234 is the port number)
