Create a group and add contacts to it
You can create groups of contacts to make it easier to find specific contacts, such as everyone on your sports team or your healthcare providers, for example.
Contacts includes a default All Contacts group.
Create a group
In iCloud Contacts, click the Add button in the sidebar, then choose New Group.
A new group is added, with a placeholder name.
Type a name for the group, then press Return or click anywhere outside the text field.
The group immediately appears in alphabetical order.
To change the group name later, double-click it and type a new name in the text field.
Add contacts to a group
Click All Contacts.
Drag one or more contacts from the All Contacts list to another group on the left.
You can add a contact to more than one group.
To select several adjacent contacts, click the first one, then Shift-click the last one. To select multiple nonadjacent contacts, Command-click them on a Mac or Control-click them on a Windows computer.
