Must choose one specific file on Mac, not folder – interPhotos - Cleanup Storage on iPhone. Find duplicate photos on Mac & iPhone. Review

Does not seem to work if more than one photo library is chosen. I selected five folders, and it found no duplicates. When I deleted all of the folders from the list to search, e.g. Pictures, Photos, ..., leaving only the specific path to one Photos library, the app found 1000 duplicates
