If you finally made the upgrade to macOS Catalina then you have a new Photos app, too, and it comes with a whole set of new features to use. Clifford Colby has details:
It can also keep your photos organized by automatically sorting your photographs by date and location, and it uses facial and object recognition to tag images for faces, objects and scenes so you can search for photos by subject matter. You can also tag photos by adding keywords — a handy feature lacking in Google Photos. And with Photos, you easily share images through Mail and Twitter, for example, by selecting a photo and then tapping the Share button.
Apple has made ease of use much, well, easier in Catalina.
