Photos out of order
I recently upgraded to 10.12.2. All my photos are now our of order. I can see that is the setting but it is grayed out. I looked in the preferences to see if this could be changed. I have 15,000 pictures and in iphoto you could look at way more pictures and they were in order so I could find them easily even if it took a few minutes.
