Bare Conductive Touch Board - serial port either not connecting or not working

Hello, first time here...

I have a Bare Conductive Touch Board which I can add sounds to and trigger fine, so all appears well so-far. I'm running it on a macbook pro 2016, OS Sierra 10.12.2

I am attempting to work with proximity sensor and have started with the sketchbook 'Proximity_MP3'. However, when uploading I get a run of console errors relating to serial port. I have tried each of the 3 ports listed, each with the same fail result - the ports available are:

  • /dev/cu.lpss-serial1
  • /dev/cu.lpss-serial2
  • /dev/cu.Bluetooth-Incoming-Port

Below is a dump of the relevant error code which is highlighted red. All other code is white and presumably fine, and there's too much to copy here.

Any advice would be much appreciated.

avrdude done.  Thank you.

the selected serial port 
 does not exist or your board is not connected

Thanks in advance.

And you've read How To Change The Code On The Touch Board With The Arduino IDE – Bare Conductive ?

Thanks for the reply and apologies for not getting back before now.

I had done all required in that link when setting the board up and have never had a problem loading new sounds on the SD card and triggering them via touch.

For proximity sensor I'm still getting the same error message listed earlier which ends with 'the selected serial port does not exist or your board is not connected'

I still have the same ports listed as above in Tools/Port - do you need a hardware profile? I'm running Avast and have tried it with the shields deactivated but that made no difference.

I don't have that part. Never heard of them before.

I suggest you contact them for tech support. It's their part.

Yep I'll do that and will write up here whatever transpires.
Thanks
