I downgraded from Catalina back to Mojave w Cataline. With my Mojave vers I cannot open my catalina vers of phlibry. How do I know if I have more pictures in PhAl than in my Photos file. Is PA just a rearrangement of photos from my Photos file? ?
I downgraded from Catalina back to Mojave because of slowness issues w Catalina. Mojave says I need to upgrade to Catalina to be able to open my photolibrary which I made while using Catalina. I just want to know if I will be missing any pictures if I just don't bother with trying to access photolibrary. I would like to know if it is possible to have more pictures in photolibrary than in my photos folder or if Photolibary is just a rearrangement of photos from my photos file.
Thank you for helping me understand this.
