OS X Mavericks brings more then 200 new features to the Mac. If you haven't upgraded yet, you should seriously consider it. One of those new features is an app called Maps. As you can imagine, this is a mapping app that works just like Apple's Maps app on iOS 7. You can zoom, you can search, you can tilt, you can pan, you can get directions from point A to point B... and you can also send those directions from your Mac directly to your iOS device (iPhone, iPad and iPod Touch). This is a great feature because sometimes, it's just easier to do the heavy lifting on a Mac, then refer to that on your iOS device. Here's how it works.
First, you need to get directions for where you want to go in Maps on your Mac. Once you have them, simply click on the action button, then choose to send those directions to the device of your choice.
As a side note, the list of devices here is pulled form your Apple ID. In my case, I have two devices tied to my Apple ID. If your devices don't show in your list, you need to go to System Preferences > iCloud and log in with your Apple ID.
Almost immediately on your device, you will see a push notification.
Simply unlock the device, and it will take you into your Maps app. From there, tap on "Start" to start your turn-by-turn directions. Voila! It can't be any easier than that.
