How To Collect all Photographs in Fotos Library on Catalina?
Someone has passed away. This person has left a Mac running Catalina (macOS 10.15.7). On this Mac is a Fotos Library. But as well – as far as I see – hundreds, if not thousands, of JPEG files on other places. I do not know, whether those JPEG files are pictures, which are duplicates from photographs in the Fotos Library.
Therefore, I would like to collect all JPEG files, which are on this Mac for import into the Fotos Library. But I do not want to import duplicates or triplicates into the Fotos Library.
How can I do that?
Then I want to copy the Fotos Library from the Mac with Catalina onto an Mac running Sequoia. Can I use the Fotos Library made with Catalina on Sequoia?
