EspruinoTools: Port not found - Unable to connect

I’m trying to connect to my Puck.js in a couple of ways but having no joy.

Running espruino -p c6:b9:c8:38:94:2b -v gives me the following output.

Unable to connect!

I get the same thing if I try to connect using a simple node app. Also I get the same if I use the output of espruino --list (/dev/cu.Bluetooth-Incoming-Port) instead of the MAC address.

I feel like I might be missing something, but this appears to be what the README suggests should work.
