OS X Yosemite: The Missing Manual

Texting from the Mac

You can now send and receive text messages (and picture, audio, and video messages) on your Mac, too.

We’re not talking about sending texts to other Apple people (with iCloud accounts). Those are called iMessages, and they’re a special, Apple-only kind of message. We’re talking about something much better: You can type any cellphone number and send a regular SMS text message to anyone. Or receive them when they’re sent to your iPhone number.

Or you can initiate the text conversation by clicking a phone number in Contacts, Calendar, or Safari to send an SMS message. Once again, your iPhone acts as a relay station between the cellular world and your Mac.

Here’s how to set it up.

First, the Mac and the phone must be on the same WiFi network and signed into the same iCloud account.

Next, on the iPhone, open Settings→Messages. Tap Text Message Forwarding. Your Mac’s name appears. Turn on the switch.

Now, on the Mac, open Messages. (If all is going well, its icon is probably popping out of your Dock at this moment, trying to get your attention.) When you open Messages, a code appears. You’re supposed to type into the corresponding box on your phone (Figure 7-3).
