    ^^ You’re most welcome!

  • Thanks for this. I had the old viewer working successfully until a week or so ago when it reverted to the new Photos app. When I followed the instructions above, it did not show me the old viewer in the list of photo viewers. I had to use the “Choose default applications by file type” option and change each file type individually, the old viewer did show as a choice using this method and did remain after a restart.
