Share iCloud calendars on Mac
If you set up iCloud on your Mac, you can use Calendar to manage your shared iCloud calendars.
If you’re in a Family Sharing group, a Family calendar automatically appears in the iCloud calendar list. Everyone in the group can view and update the same Family calendar, so it’s a good way to keep track of events such as family camping trips and violin recitals.
