Hello! So I got a new Mac, lucky me! Now I would like to move my Photos.app library (150gb) to the new Mac. It's iCloud library. If I just download it on the other Mac via iCloud, a part from taking ages it will sync everything but not the Faces album (only the metadata) and not smart albums... If I physically move it from the old to the new mac, iCloud thinks it's a new library and when I prompt it to sync it starts uploading all 17000 photos (which are all already online of course). Question here: will iCloud see the duplicates and skip uploading or will it actually duplicate all the pictures? Final option: migration assistant from Time Machine. A part from the fact that I get all the old stuff I don't want when I open photos app after the migration it prompts me to repair the library. After that, it takes ages to rebuild thumbnails. Ages, numerous crashes and at least 4 or five app restarts.... Am I missing something? Is there a way to easily migrate from old to new computer the library without re-syncing everything with iCloud and without having to download everything? Thanks!
