I have recently added a number of photos to the Photos App on my iMac, some automatically via iCloud from my iPhone, and some transferred via SD card from a camera. I cannot find any way to make them appear in the correct chronological order. I have done this before after previous trips away and it just seemed to happen automatically. The photos appear in the order they were "added" iPhone first and the the camera ones. I have found a "Sort" option in the View menu, but when I click on it I only see one greyed out option "Keep sorted by oldest date added". I cannot see anywhere how I can change this to something like "Sort by date picture taken" Any suggestions will be gratefully received. Incidentally I tried moving them all into a new Album to see if I could sort them there, but the result was the same.
