I am working on our family tree, which has grown to 330 persons. I am 90% up to date with photos on the TREE. As I receive pictures to update, I go to the person with Photo missing, I click to upload photo and NOTHING happens? I have a macOS 21" . Apple informed me to update to High Sierra, Version 10.13.1 which was 3 days ago and since than I can NOT upload Photos.
HELP
