With USB cable connection (no cloud) to import from updated iPhones (11 Pro Max, 12 mini, and 13 with their updated iOSes) into updated macOSes (Ventura v13.x, Big Sur v10.11.x, and Mojave v10.14.x)'s Photos app, I noticed imports show already imported medias and missing brand new medias.
Others and I noticed this problem in our multiple macOSes with iPhones: https://discussions.apple.com/thread/255565285 and https://talk.tidbits.com/t/does-anyone-have-problems-importing-iphones-medias-into-macos-photos-app/27406/.
Thank you for reading and hopefully answering soon. :)
