I have tried different cords, although I am not sure if they are the wrong type. The power light is green on the board and the other light is blinking. The board is a RoboGets Arduino Uno R3 Compatible ATmega328P Microcontroller Card. I have tried to install drivers. The only ports available are dev/cu.Bluetooth-Incoming-Port and dev/cu.SONYSRS-X3-SPPDev. I am choosing the Arduino/Genuino UNO for board in chooser. Why can't my MAC see this device?
