I've received a shipment of new UNO board and am running into issues uploading.
I'm working off a Mac. Both ports (1411 and 621) are fine as I can upload to an older UNO board.
I've updated to the newest version IDE and have followed the steps outlined here: http://www.arduino.cc/en/Guide/Troubleshooting#toc1
Have read through different threads and haven't found anything.
Cable is fine.
Bootloader is fine.
There is power.
Board is step to UNO
Suggestions?
Please describe exactly what the issues uploading are.
The issue is that the serial port is not recognized and I can not upload to this new board...
Sketch uses 3346 bytes (10%) of program storage space. Maximum is 32256 bytes.
Global variables use 312 bytes (15%) of dynamic memory, leaving 1736 bytes for local variables. Maximum is 2048 bytes.
avrdude: ser_open(): can't open device "/dev/cu.usbmodem1411": No such file or directory
Problem uploading to board. See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.
It is not the program itself or the serial ports on the computer as I can upload it to another older board without issue.
The UNO board has the following chip: ATMEGA328p u-ph
I have tested this on two of the new UNO boards I'd received and so it is not an issue with just one faulty board. I believe the Bootloader is working as the green LED goes through it's flashing routine.
I first uploaded this usign IDE version 1.8.2 and then updated to the latest version 1.8.6
It's someone with the boards.

Did you change the "port" setting to match the new board?
If you've previously only had one board, it'd be easy to get into habit of not paying attention to the "port", because the IDE will just remember it from the last time. But if you have more than one board, they show up with different device names, depending on ... all sorts of stuff (manufacturer, serial number - things that are sent to the PC during USB "discovery.")
Try adding the CH340 driver

The appropriate board is selected. The option to select a port other that bluetooth doesn't show. It simply doesn't recognize the board. I've restarted the program with the board connected and the board disconnected. It doesn't make a difference.

How can I add this?
