If you have an Apple computer, there’s a good chance that you’ve used the Photos app to manage your photos. But if you want to delete photos from your Mac, there are a few steps you need to take. First, open Photos and click on the three lines in the top left corner of the screen. This will show a list of all of your photos. On the right side of this list, you’ll see a list of photos that have been imported into Photos from other devices or online sources. If any of these photos have been added by someone else and you want them gone, just drag them off the list and delete them from Photos. If all of your photos are in Photos but some are not, then open Finder and type “Photos” into the address bar and hit return. Then select all of your pictures from before (or after if they were imported through Finder) and hit enter.
