Duplicate Photos
Is there an automated way to find and remove duplicates from Photos?

Hi
There are no facilities in photos to automate finding and deleting duplicates, so either
* manually,
* or using an app designed to work with the photos library (Ie one that marks the photos or puts them in an album, and lets you review and then delete them, rather than doing the delete itself.
Do NOT use a general file duplicate finder not designed to work with the photos library. They will damage your photos library and likely cause loss of your photos.
I personally use PowerPhotos (I also use this for copying images and data between libraries) https://www.fatcatsoftware.com/powerphotos/
Another suitable app recommended by experts here is PhotoSweeper (I have no personal experience of this one)
Both are paid apps. PhotoSweeper is the lowest cost and can recognise duplicates based on content, but PowerPhotos provides a lot of functionality in addition to the duplicate detection.
