Traveling to a friend's new house and not exactly sure how to get there? if their new address is in your Contacts, then you can quickly and easily pull up a map to see where they live. Once you have Maps open, driving directions are just few clicks away.
To Map a contact's address, just open the Contacts app in OS X and select the name of the contact you wish to map. If you added an address to the contact, it should appear below their phone number, email and home page information. Just hover your mouse cursor over the address and you should see a link for "Show Map" appear on the right side of the address.
Just click that link and address will open in Apple Maps. The address will be highlighted by a pin, which you can use to view additional information about that location. Just click on the pin and then click on the "i" button to open a dialog that allows you to add that address to your bookmarks or get driving directions to that location.
