This is my second setup and I am stumped, my first was an Arduino MEGA 2560 with a Ramps 1.4 board. It setup fine and the Tools/Ports showed a /dev/cu.usbmodem141411 (Arduino/Genuino Mega or Mega 2560) for the ports, worked well and the uploads were successful.
Now I have an Arduino UNO (Real thing) using the same usb cable as above and when I go through the setup I get the screen for ports shown in the attached screen shot. No usb modem shows and I cannot upload using either of the 2 ports shown.
When I do a search on the issue I only get results for use with a Windows PC, none of which help with the mac.
I am out of ideas, can someone help or is it the board.
