      Hi Forum, did anyone had the problem with MacOS Sierra serial port not found problem. I mean, I cannot see the USB serial port either on Atom or on Arduino IDE. I tried one solution available on youtube https://www.youtube.com/watch?v=wyocdvAKo64&ab_channel=RCboat But this works one time good but afterwards again having the same problem.

        That video is about the CH340 USB serial adapter, but what are you using? The Pycom expansion board?
        If so you want to install the FTDI VCP drivers http://www.ftdichip.com/Drivers/VCP.htm

          By running this command on Terminal "ls /dev/tty.*" system returns me "/dev/tty.Bluetooth-Incoming-Port" So, no USB serial port!!!

            @jmarcelino thx for the quick reply. I have installed the VCP driver from the link you have provided. But still having the same problem.

            Yes I am using expansion board. And trying to connect with Atom IDE with Pymakr Plugin.

              Does it work if you reboot macOS?

              If not you probably are using a charge-only microUSB cable. Try another cable.
