Use Family Sharing to share photos and videos on Mac
After the family organizer creates a Family Sharing group, family members have a shared photo album called Family. Members can view and download photos and videos that other family members add to the album. Use any of these apps:
Photos on your Mac. See What are Shared Albums?
Photos on your iOS (iOS 7 or later) or iPadOS device. See “Share photos with Shared Albums in iCloud” in the user guide for iPhone, iPad, or iPod touch. For a device that doesn’t use the latest iOS version, download the user guide from the Apple Support Manuals website.
Before you can use the family’s shared photo album, you must join a Family Sharing group.
