The above method is doable if you have a small library of photos and you have the time to find the duplicates manually. But if you have a lot of pictures, you can use a third-party app to find and delete all the duplicate images on your Mac. Here’s how:

1) Download Photos Duplicate Cleaner from the Mac App Store and open it.

2) Click Add Photos Library and allow the app to access your photos when prompted. If you want to find and delete duplicate images from a Finder folder, click Add Folder.

5) The app will scan all the duplicate images in your photo library and show them to you as groups. You can scroll and manually check the tiny box to select identical images. Make sure you leave one copy unchecked. But if you want to make things quicker and skip the manual checks, click Auto Mark > Continue from the top left. This will automatically select all duplicate files leaving one of their copies unchecked.

6) Scroll down the duplicate list to ensure the app has correctly selected the duplicate files. The selected ones (those that will be deleted) will have a red bottom border, and the ones that are not selected (those that will not be deleted) will have a green bottom border. Finally, when done with the manual inspection, click Trash Marked > Trash Photos.
