I'm trying to use my Wemos Mini D1 with the IDE on my macbook pro running OS Sierra.
I have searched the web for info and installed suggested drivers etc but when I get to actually connecting the board to the usb my mac crashes spectacularly
The problem is the CH340 driver is not compatible with Sierra (or at least at one point this was the case, it's possible the CH340 manufacturer has fixed it since then. Please see: https://forum.arduino.cc/index.php?topic=428349
for some solutions.
