Can you sync only a group of contacts from a Mac to an iPhone?
This wasn't intended to be a Jeopardy question, but I think I've figured it out.


On the iPhone, go to Settings » iCloud and set Contacts to  Off.
On the computer, turn off iCloud contact syncing
Connect the iPhone to the computer
Click on the iPhone button that appears top right in iTunes
Go to Info
Check Sync Contacts
Select Selected Groups
Select the group you want synced.
