Where the Mac camera really shines, however, is in video communication.
Thanks to your Apple Photos library, you can save all of your camera photos in one place, syncing them to your iCloud storage as you do so. Now that you know how to turn on the camera on a Mac, you can use it to stay in touch with loved ones, take impressive selfies using Photo Booth, or even sign a PDF on a Mac using the Preview app. If you download and install software online that isn’t from the App Store, you’ll need to make sure that you really trust the source before you allow it access to your Mac camera feed. Because of this, the risk of installing an unsecure app will be lower. These apps will have been vetted by Apple before being approved.
