Transferring photos with meta data in Mojave and Monterey without ICloud
I've got thousands of photos from the 70's & earlier. I do not use ICloud and want to move photos between IMacs & photo libraries. I have manually adjusted all dates, identified locations & made descriptions. When I go to transfer some of the photos to a different library, all meta data becomes inaccurate. How do I transfer between libraries & not lose the meta data that I've put in?
