All my Photos have disappeared
Just before the Catalina upgrade my iPhoto library just vanished. I think I had just updated a couple of Apps on my Mac, and when I went to look for some photos it just had a few photos taken over the last week. I managed to find an iPhoto Library, but when I looked at that it only had photos and video from before 2016 (I think), but it was letting me view them. Since updating to Catalina, when I try to view them Photos asks me if I want to switch Libraries. Not sure if I do this I'll lose my current (all be it small) library, and whether I will be able to recover the thousands of photos from 2016 to 2019?
Help! What can I try?
I literally have hundreds of videos and thousands of photos that I can't find.
Not used Time Machine to back up, and feeling really gutted!
