Set up iPhone to get SMS, MMS, and RCS messages on Mac
You can set up your iPhone so that you can receive and send SMS, MMS, or RCS text messages on your Mac. After you set up your devices, these messages appear on both your iPhone and your Mac. When you send a message to someone who uses a phone other than an iPhone, your message is sent as an SMS, MMS, or RCS message.
Note: Availability varies by region and carrier.
Important: To receive and send SMS, MMS, or RCS messages on your Mac, you must be signed in to the same Apple Account and be using iMessage on your iPhone and Mac. See the Apple Support article Continuity features and requirements on Apple devices.
Go to the Messages app on your Mac.
Choose Messages > Settings, then click iMessage and make sure you’re signed in.
On your iPhone, go to Settings > Apps > Messages, then make sure iMessage is turned on.
Tap Send & Receive, and make sure the Apple Account listed at the bottom is the same Apple Account you’re signed in to on your Mac.
Tap , then tap Text Message Forwarding.
Note: If you don’t see Text Message Forwarding, make sure you’re signed in to the same Apple Account on both your iPhone and your Mac.
In the list of devices, turn on your Mac.
