I tried to open Photos and got this message:
The library "Photos Library" is from a newer version of Photos.
Please upgrade Photos to open this library.
When I do this, there are no photos. All gone. I looked in Pictures and see Photo Library and
Photo Library 2. I look in Get Info for both. The original Photo Library shows 35GB. The Photo Library 2 shows 2.5MB. But when I click on Photo Library (original, 35GB) I get the above message.
I did reinstall Mojave beforehand for another reason. I have iMac Mojave.
What should I do now?
