Manage family accounts, share files using iCloud Drive, and much more
Family members
Open System Preferences’ iCloud pane and click Manage Family. In the Family Members tab, you can add up to five other members of your family to a sharing account. Once invitations have been accepted, everyone in the family will be able to share (most) purchased apps, games, books, and music.
iCloud storage
In the My Apps & Services tab, select iCloud Storage. In High Sierra, you can share a 200GB or 2TB plan with your entire family. This makes those tiers great value – one of them is likely to provide enough space for everyone’s files and iOS device backups.
Location sharing
Select Location Sharing in the My Apps & Services tab. You’ll see that you no longer have to reach for your iOS device to manage which family members can check your location, as High Sierra enables that too.
Share a file
Individual files, but sadly not whole folders, that are stored in iCloud Drive can be shared with other people, and not just in the sense of sending them a copy. Go to iCloud Drive, Ctrl-click a file, and pick Share > Add People.
In the sheet that opens, you can enable others to access and even edit the file. Invitations can be sent by email, iMessage, AirDrop, or social media, or you can copy a link to paste elsewhere. We’ve wanted this back since MobileMe’s discontinuation!
