Normal text or SMS messages are routed through your iPhone. In fact, there are two types of messages that you can send and receive on a Mac system. You can reply to some important message through SMS message or even iMessage by sending or receiving messages through your Mac system itself. If you are busy over something on your Mac OS system and have no time to access your smartphone, then this feature comes a handy. Amongst all, the Messages app has been one of the greatest updates so far as it lets you send and receive text messages on a Mac system without even taking out your phone. Some of these apps include Maps, Messages, Notes, Photos, and iBooks. Several apps for iPhone and iPad with some updates have made it to the Mac OS as well in the recent past.
