It seems I have had a boards failure, or at least something to wrong with the way my mac is reading the ports. Any advice or help appreciated.
I bought a nano v.3 and an uno r3, cheap ones from China, DX to be precise, and it seems neither of them connect to my mac. Both boards power on and seem to light up and function, and the uno blinks the on board LED, but neither show up for me to set the port. I get the Bluetooth port but not Com1, and I cannot send sketchs to either board.
I have followed the online guide to set the port multiple times, swapped USB leads and USB ports, checked the original Duinotech uno (works fine) shows up the correct selected port. I have followed a guide to instal FDTI drivers to no avail. Other than turning it off and on again I don’t really know what else to do,
Running the latest OS Sierra, with the latest arduino (1.6 I think), is this more likely to be a software issue or a (cheap) hardware issue?
