I have a Mac (high sierra) and recently got a Elegloo MEGA2650 R3 Board (and kit), yet upon instillation I could only connect to a /dev/cu.bluetooth-incoming-port. I have tried multiple USB ports to no avail, and only have the one USB cable. I have tried restarting and re-downloading but nothing.
Here is the error message I receive when I attempt to upload a sketch (in this case it the Blink tutorial)
Arduino: 1.8.9 (Mac OS X), Board: "Arduino/Genuino Mega or Mega 2560, ATmega2560 (Mega 2560)"
Sketch uses 1460 bytes (0%) of program storage space. Maximum is 253952 bytes.
Global variables use 9 bytes (0%) of dynamic memory, leaving 8183 bytes for local variables. Maximum is 8192 bytes.

Hope this is enough info, let me know of more is needed!
Thanks

If this has been answered I apologize, please just send me the link.
Have a look at the chip to the right of the usb connector for a part number.
You need to figure which chip the board is using for the usb to serial conversion. It is common for the clone boards to use the CH340G which needs a driver on the Mac. If it uses the original atmega16, the driver should have been installed with the Arduino IDE and the problem could be the board or cable (although unlikely).
Link for CH340 drivers (with Homebrew support)
Try using an inexpensive USB hub. Plug the hub into your Mac, and plug the Mega board into the hub. Then try it out and see if you can upload.
If that doesn't work, at the top of the forum you will see a post called "Loop-Back Test Instructions". Do a loopback test to check out your Mega board to see if it is OK.
