Useful info for remotely accessing server through "Terminal" on a Mac.
I followed the steps outlined by Mark. It was very helpful.
Additional notes: be sure to use ssh and your server IP address
Initially had trouble because my macOS ID was different than the ID assigned to me for server access. I had to go on my computer into the Apple menu/System Preferences/Users&Groups, then I had to unlock my user account and change the short name so that it matched my remote access assigned user name.
Thanks!
