Are you using iCloud Photo Library with "Optimize Storage"? The file may be unreadable, it may be missing, or stored in iCloud and cannot be downloaded quickly enough, because the network is slow. This can have several reasons: For the duplicate in your Photos Library the original image file may not yet have a thumbnail image and so it cannot be shown. When a duplicate comes up in the window asking if I want to import, it only shows the image I want to import, and it's blank where the "original" photo should appear. This will protect them from accidental deletion.Īs to this problem: I'd check in Photos the state of the photos without thumbnails. Select them and use "File > Consolicate" to copy them into the Photos library. If you have referenced files in Photos it would be safer to turn them into managed files.If the photo is still in iPhoto, it will not need any extra storage. Is this album empty? Then all photos in Photos are new copies of the photos migrated from iPhoto, but stored efficiently.You can do that with a smart album in Photos.įile > New Smart Album. So try to find out, if all photos in your Photos library are managed inside the library. if you delete a referenced photo from the iPhoto Library and its original image file, the photo will be missing from the Photos Library. If your iPhoto Library contains "referenced" images, the Photos Library is referencing the same original image files and the photos have not been duplicated by the migration.But these duplicates do not need any additional storage, because they are hard linked files, see this document: Photos saves disk space by sharing images with your iPhoto or Aperture libraries - Apple Supportīut if photos are managed, you can safely delete photos from iPhoto or Photos without deleting them from the other library as well. Photos duplicated the images when it created the migrated Photos Library. If all photos in the iPhoto Library are "managed" and iPhoto has copies inside the library, your Photos library has also private copies inside the library.Whether the photos are copied into the library or referenced will depend on the preference "Importing". Referenced Library: The photos remain in their original location outside the library and are just referenced by Photos or iPhoto.Managed Library: The photos are copied into the iPhoto Library (or Photos Library) and and stored inside the library package.Like Photos, iPhoto has two different ways of importing photos: This will depend on how you imported the photos into iPhoto. Also, when I migrated from IPhoto to Photos, did the original files stay in the same place on the computer or did they move? If I delete a photo in IPhoto, is there any chance I'm also deleting it out of Photos?

Just picking up some loose ends in your original post.
