I’ve got the same problem.
I Bought two Nanos and connected them with 3 different USB-Calbes.
My Macbook Pro finds the FTDI drivers.
Now I use the Arduino-Programm and can’t upload sketches, that work on the Arduino Uno.
Unless the Arduino shows the dev/tty…-A603RTIG as possible Port.
Basic blinking works on both Nanos.
Hope you can help me out.
