How do I create a groups OS X Mavericks Contacts app that remains local to my machine? When creating a new group in the OS X Mavericks version of the Contacts apps the group is automatically synchronized to iCloud. I'd like to keep this group local to just the machine where I created it.

How can I make a group that stays local to the machine and does not sync to my iCloud account?
Open Contacts
For the On My Mac account, click the + button to add a new group.


Enter a group name and press Enter.
