I’ve been using OSX for a few years now but every once in a while I run into one of those obvious features of the OS that I never knew about. This happened just the other day with the Address Book.
The Mac Address Book has a very full featured print facility which lets you print envelopes, mailing labels, even a pocket address book. You just need to select a card or range of cards and select Print from the menu. Check out the video below to see the entire process.
Have you come across anything about OS X that you never knew existed, tell us about it here.
