upload to Arduino UNO by MAC not possible

Using Arduino IDE 1.x
1

The problem is possible the lack of a good driver. Mac (OS 10/13/6) doesn't recognise my new UNO. How can I get the good port driver.

2

The Arduino troubleshooting site says: "On the Mac, the serial port should be something like /dev/tty.usbmodem621 (for the Uno or Mega 2560) or /dev/tty.usbserial-A02f8e (for older, FTDI-based boards)." But nothing like that does appear.

That's a CH340G based clone.

You can get the CH340 driver for macOS here:
