How do I use Arduino Uno with Mac OS High Sierra? Nothing appears on my desk to when I plug in the arduino board to my use port.
- Download the Arduino IDE from: https://www.arduino.cc/download_handler.php?f=/arduino-1.8.8-macosx.zip
- Install the Arduino IDE: https://www.arduino.cc/en/Guide/MacOSX
- Start the Arduino IDE
- Tools > Board > Arduino/Genuino Uno
- Tools > Port > select the port of your Uno
Now you are ready to write some code or open one of the example sketches (File > Examples), then upload it to your Uno.
If you're using a clone board with a CH340G, you need to hunt down the mac OS high sierra driver for it - there is an older version of the driver floating around that doesn't work with high sierra, btw.
