How to find and remove duplicate photos?

Hello Loisbikelane,

Thanks for that info and for choosing the Apple Support Communities. If we understand correctly, you are running out of iCloud storage, and you think it could be related to duplicate pictures in the Photos app on your Mac. First, we recommend you don't use any 3rd party software to remove duplicates as this could be harmful and here is more info:

As far as managing iCloud storage, see if the info in this resource helps:

Cheers!

The next version of Photos on macOS Ventura, coming this fall, will include a duplicate detection in Photos as announced here: macOS Ventura Preview - New Features - Apple. "Photos identifies duplicates in a new sidebar item, so you can quickly clean up your library."

If you can wait for the official release, you can easily clean the Photos Library from duplicates, directly in Photos on you Mac. Until then, try to remove redundant photos and bad shots to save some storage. Even the best duplicate Finder cannot decide which photo is the better shot, when you have to decide between two similar photos. It is a matter of your personal taste and preferences.
