Error "programmer is not responding" again (Duemilanove, Mac OS High Sierra)

Hi,

When trying to upload a program to my Duemilanove I am getting the following error on Mac OS 10.13.6 High Sierra:

Arduino: 1.8.11 (Mac OS X), Board: "Arduino Duemilanove or Diecimila, ATmega328P"

...

avrdude: Version 6.3-20190619

This error has been discussed in this forum many times and I have already tried the suggested solutions:

  • verified hardware connection: The same board with same USB cable works fine when connected to a different computer (with Mac OS Sierra 10.12.6)
  • verified correct settings under tools (board type, serial connection, processor(
  • checked loopback test: works fine
  • reinstalled FTDI drivers
  • press rest button just before uploading: no effect
  • use "old bootloader" option in processor selection under tools (only available for nano boar): no effect

So, apart from getting a new board, what else could I try to resolve this issue? Note that the board is fine, but just doesn't work on this particular computer.

Thanks a lot.

Cheers,
