Send text messages to anyone from your Mac

If you have an iPhone with an active celluar plan, you can set up Messages to send and receive SMS and MMS messages from your Mac. Such messages don't require the recipient to be using iMessage or an Apple device.

1. On your iPhone, go to Settings > Messages > Send & Receive. Add a check to your phone number and email address.
2. On your iPhone, go to Settings > Messages > Text Message Forwarding, then choose to allow your Mac to send and receive text messages from this iPhone.
3. Check your Mac for a verification code, then enter that code on your iPhone.

To get all of your iMessage and SMS/MMS messages on all of your Apple devices, you can set up the SMS and MMS feature of Continuity.

Have a great day!
