It’s great to be able to keep track of addresses for friends and places around town in your Contacts app. Having all the address info in a ready Contact makes it super simple to launch Maps in Mavericks from the Contacts app when you want directions to a party in town somewhere.
And, while you can easily send directions from Maps app to your iPhone, it’s also helpful to just say to Siri, “Directions to Jill’s house,” or “Get me to the movie theater,” and have your iPhone just pull up maps based on that name in the Contacts app.
Mavericks makes it incredibly simple to put addresses for all the places you might want to go right into your Contacts app so you can do just that.
