How do I remove duplicate photos in Photos?

Not without knowing what you have and what you are doing - that is one of the problems with ThreadJacking someone else's solved thread - you have a different setup, different workflows and a different problem

Usually duplicates are because you have imported the same photo multiple times - it can be due to HDR and other reasons

To remove photos from Photos, is easy. Tap the thumbnail and the picture will open. Tap the trash can icon on the top right and press the "Delete" option. Photos will warn you that the photo is located in a number of albums, if in fact it is. Just hit Delete again and the photo is moved to the folder "Recently Deleted".

The REAL problem you have to solve is FINDING the duplicates. That is best done by selecting groups of pictures and exporting them to a secondary folder. Find the duplicates by dragging thumbnails together. Use the instructions above to remove the duplicate. BE aware that Photos will tell you that the picture will be deleted from AN album, IFF the ONLY album it is located in is the current one.

Or as posted twice above to automatically identify them

or use a safe, tested duplicate identification program like PowerPhotos, Duplicate Annihilator for Photos or PhotoSweeper for Photos to identify then and then delete

Careful - their web site sounds like it may directly delete photos which can damage or destroy your Photos library - you should never let any program ever directly delete photos - the only safe way is using a program that puts the dups in an album so you can use the Photos Application to safely delete them

I have the same issue on my MacBook Pro mid 2010. It seems that every time I get and update to Photo's even going way back to IPhoto, I wind up with dupes. I even have multiple Libraries that I did not create. And the Libraries contain slightly different photo's.

You may have created the multiple Photos Libraries by opening the iPhoto Library in Photos multiple times. Whenever you use Photos to view an iPhoto Library, it will create a new Photos library. Also, if you launch Photos and it cannot open the current Photos Library, because it cannot access the drive or the drive is not compatible, you may find a new Photos Library on your system drive in the Pictures folder.

Do you know anything about a Gemini 2?

I have and both Gemini 2 and Photos Duplicate Cleaner but neither seems to accept a batch of my photos being dragged and dropped into place.

Any suggestions very gratefully received !

The "why" might be the same reason I just found out on my MAC. With my configuration, The Photo Stream imports photos, automatically, in the background. It's very useful as I often take pics I want to post in an ad or something like that. The issue for me is that it does NOT import videos and I wanted to move some videos over from my phone so I imported manually. It used to be that this was a perfectly safe thing to do. It's not any more. All the photos are duplicated (1000's of them) and the videos have one version. Going forward I need to remember to import videos only.

Sorry, don't know how to fix the problem.

**** off Larry no one needs your passive-aggressive messages here. Yes this happens to multiple people and yes there probably is a function that automatically does it so as I said **** off if you don't know how to fix it.

Everyone I know HATES Photo app and we are not Apple geeks who are duplicating on purpose. You would think, the great Apple folks would hear us and simplify!

Also, the 'thumbnails' that duplicate and identify faces --added to the library of mess--is no help, either.

I have recently encountered the same issue with duplicated photos. In my case it seems to be limited to photos taken with iPhone. When I compare the duplicated, there is a new file extension used .heis for more recently photos and during some point of the transition some now have both .jpg and .heis extensions.... causing the duplicates.

I have not dug too deep into the issue yet... whether this was a result of my migration to a new MBP running High Sierra or an iPhone update or both....and whether this file format is a good thing.

Do you get this window when you launch PDC?

The library shows up in the bottom window and its checkbox selected to start the scan.

The manual for PhotoSweeper does not show support for Photos Library 4? Have you used this utility with this library?

Same question? Same answer as given in Feb

and it is not possible to have multiple libraries unless you create them - nothing magically creates Photos libraries ever - users do that

I've heard bad things about Genini. Photos Duplicate Cleaner should be able to help you identify photos in your Photos library. Open the app and then select the library.
