Deleting your duplicate photos
Once you’ve finished choosing which photos to keep and which to trash, click the “Trash Duplicates” button in the upper right corner. How your duplicate photos actually get deleted depends on what version of macOS you are running.
macOS 10.15 Catalina or later On macOS 10.15 and later, PowerPhotos can directly delete the duplicate photos from your library for you, so there are no additional steps you need to take. You will see an additional confirmation warning displayed by macOS before the deletion is finalized.
macOS 10.14 Mojave or earlier On earlier versions of macOS, Photos does not provide a mechanism for PowerPhotos to directly delete the duplicate photos that it has found, so the final step of deletion must be performed manually.
PowerPhotos will create an album named “PowerPhotos duplicate trash” in your Photos library and populate it with all the photos that have been marked to be trashed. PowerPhotos will then walk you through the steps needed to delete the photos from the library. Note that all these steps are done in the Photos app, and not from within PowerPhotos.
- Select Trash Album Bring Photos to the front and select the “PowerPhotos duplicate trash” album in your album list. PowerPhotos can perform this step for you by clicking the “Select the album for me button”.
- Select All Photos Select all the photos in the “PowerPhotos duplicate trash” album, either by pressing command-a or choosing “Select All” from the Edit menu.
- Delete Photos Control-click one of the photos and choose “Delete N items” from the contextual menu that comes up. This will move all the photos into the “Recently Deleted” album, removing them from the library. Pressing command-delete will also delete the photos, but note that just pressing the delete key alone will only remove the photos from the album, and not delete the from the library.
After deletion Once the photos have been deleted, they will remain in the “Recently Deleted” album until Photos permanently deletes them in 40 days. This gives you a chance to “undelete” them for a while in case you change your mind. You can do that by selecting the “Recently Deleted” album, selecting the photos you want to undelete, and clicking the “Recover” button. If you want to delete the photos right away to free up disk space, you can instead click the “Delete All” button, which will delete them immediately and permanently.
