I followed your instruction but it resulted in the same error message,
Same error message, but this time it also shows the avrdude command that generated the error, which is what I was looking to get. Unfortunately I don't get any clues as to the problem from that but maybe it will be helpful to someone else here on the forum. I don't have any experience with macOS.

however, there is no orange bar nor button.
That is strange. Normally when there is an error the teal bar that says "Uploading..." will turn to an orange bar with the button to copy the error messages. You can always just copy the full contents of the text from the black console windows at the bottom of the Arduino IDE window. The only difference between that and the button is the button adds a little more information (OS, IDE version, board selected).
