Easy way to remove multiple duplicated photos from iPhoto
Dear Apple Community,
I have nearly 50k photos in my iCloud. These are synched to my Mac and iPhone. Sometimes, when I upgrade my iOS on either device, the synch stops working, and I usually need to remove and re-download all photos, which is a pain.
Somewhere along the way, perhaps when there are synching glitches, I've ended up with dozens of unwanted copies of specific photos. In my whole collection, I probably have 1000's of duplicates that I don't want.
Are there any utilities or apps that could help me clear these out? If I try to do it manually, it takes a long time, plus I am worried that deleting on one device may not always remove the duplicates from the cloud, even though the prompt says that it will.
Thank you very much!
