Using the built-in SSH client in Mac

You must launch the Terminal app and use the command line. If you are using a password to access the remote system, then you use the command like this making sure to substitute "<user>" for the actual user name of the remote system with SSH access and "<address-remote-system>" with the IP address or DNS name of the remote system to which you want to connect.

ssh  <user>@<address-remote-system>

example:

ssh  hwtech@my-server.local

This will only give you access to the command line on the remote system. If you need GUI access (aka graphical interface), then you need to also initiate a remote VNC or remote Desktop session as well after you make the secure SSH connection (assuming the remote system is configured for VNC access). A VNC graphical connection would require different options for the SSH command as well.

Thank you! I will try it as you suggested.
