So, I am not a very computer literate individual. I realize instructions have been posted as to how to create a multiplayer server on a Mac, but, I simply don't understand them. I have found the info.plist file, but I don't see the line that I am supposed to edit. I sincerely hope I'm not wasting anyone's time but I just don't know what to do. I apologize for my ignorance.
