Use iCloud to share photos and videos on your Mac and iOS devices
Your family has a shared photo album called Family. You can view and download photos and videos other family members add to the album, and you can add your own photos and videos. Use any of these apps:
Photos on your Mac. See What are Shared Albums?
Photos on your iOS device (iOS 7 or later). See “Share photos with Shared Albums in iCloud” in the iOS 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.
Aperture, if it’s installed on your Mac. See Aperture 3.6 Help.
Before you can use the family’s shared photo album, you must join a family.
