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.

To Connect:
ssh username@serveraddress.com
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 username@serveraddress.com
(where 1234 is the port number)
