Nova OS X Support

I tried following the instructions in this guide to access my Nova on my Mac: https://support.hologram.io/hc/en-us/articles/360035213154-Sending-AT-Commands-To-Your-Nova

I plugged my Nova into a USB port. Only Bluetooth devices show up when I runls /dev/cu.* or ls/dev/tty.*

Is it possible to access the Nova from a Mac computer?
