If someone still struggling:
Thanks, that helped,
but for me (Also on Mac) the path turned out to be:
PDG_IMAGEMAGICK = "/opt/homebrew/Cellar/imagemagick/7.1.0-6/bin/magick"
Found the path by using the "Find Any File" App, {Name} {is} {magick}, and choose the one that seemed best (not the Alias).
Be aware there is the "ImageMagick Binary" parameter-menu on the TOP node.
This worked, as opposed to the directing to a self-made $PDG_IMAGEMAGICK_DIR and the "Use System Path", which did not work.
As such: PDG_IMAGEMAGICK_DIR = "/Users/username/Documents/Codecs/ImageMagick-7.0.10/bin"
Maybe this helps someone.
