I have a USB cable connected between my MacBook Pro and the Raduino (Bitx40v3 up and running ok) but the IDE (1.8.2) via the Tools->Port doesn't see the Raduino (I set board to Nano)
Same cable on a MS Surface sees the Raduino via the IDE just fine.
MacBook Pro sees an Arduino Uno just fine with a different USB cable.
i suspect a need a USB driver for the MacBook Pro to match the Raduino.
OS X version is El Cap.
Any suggestions are welcome.
