Ok I have discovered the issue was me not entering the commands properly. Now my problem is that I hit the erase button while troubleshooting as per a forum thread and I think I probably need to reinstall something onto the board before it will connect. I found this thread, but it seems to be specific to windows:

I have considered boot camping Windows on my mac or trying to use my raspberry pi with raspian on it to configure the board, but this seems unnecessary. If you could point me in the right direction for reloading the firmware to the board and getting to the point where I can start over at the setup procedures again, I would appreciate it.
