You can do that by selecting the “Recently Deleted” album, selecting the photos you want to undelete, and clicking the “Recover” button.

This gives you a chance to “undelete” them for a while in case you change your mind. Once the photos have been deleted, they will remain in the “Recently Deleted” album until Photos permanently deletes them in 40 days. 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. This will move all the photos into the “Recently Deleted” album, removing them from the library. Delete Photos Control-click one of the photos and choose “Delete N items” from the contextual menu that comes up.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.PowerPhotos can perform this step for you by clicking the “Select the album for me button”. Select Trash Album Bring Photos to the front and select the “PowerPhotos duplicate trash” album in your album list.Note that all these steps are done in the Photos app, and not from within PowerPhotos. PowerPhotos will then walk you through the steps needed to delete the photos from the library. 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. 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. You will see an additional confirmation warning displayed by macOS before the deletion is finalized.

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. How your duplicate photos actually get deleted depends on what version of macOS you are running. Once you’ve finished choosing which photos to keep and which to trash, click the “Trash Duplicates” button in the upper right corner.
