Why does Photos duplicate photos when importing?
There are two possible reasons.
When you import pictures from your iPhone or camera to Mac using Photos, Photos recognizes new photos and lets you import them by clicking Import All New Items. However, sometimes the recognition may fail and Photos imports pictures that are already in your library, leading to duplicates.
Also, the issue could be caused by iCloud, if iCloud Photos and Optimize iPhone Storage are enabled on your iPhone.
Can Mac Photos find duplicates?
Photos on Mac can detect duplicates when importing. When you import a picture that already exists, Photos will recognize it and try to prevent you from importing duplicates. The detection won’t work if you change the picture’s name and then import.
However, Photos can’t detect the duplicate photos that already exist.
