Failure uploading to Nano Every

Official Hardware Nano Family Nano Every
1

Hello, I have been working with various Arduino platforms for years but I am unable to upload any sketch to my new genuine Nano Every board (bought straight from the Arduino website).
I have tried Arduino IDE 2.0.1 and platformio.
I ensured I have the Arduino megaAVR board library installed and "Arduino Nano Every" selected from the board drop down. I have tried both options for Register Emulation (ATMEGA328 & None). When I select "Get Board Info" I receive info on the Arduino Nano Every.

When I attempt to upload any sketch (including Blink.ino) the IDE uploader hangs, then times out. (See attached verbose output.)

Using Port : /dev/cu.usbmodem14244401

You need to select the port of your Nano from the Arduino IDE's Tools > Port menu.

Is /dev/cu.wchusbserial14244401 listed on that menu?

/dev/cu.usbmodem14244401 is the USB port that the Arduino Nano Every is plugged into.

I have also tried 3 separate USB cables, various USB ports on the computer. All similar result.

UPDATE:
Moved my setup from a Mac to Windows machine and it works just fine. So frustrating. One more win for Windows.

Hi @FancyChancie. Did you try restarting the Mac machine? On rare occasions, the port might get stuck in an unusable state. Restarting the computer restores the port to usability in this case.
