Hello Sorcerer2006,


Thank you for reaching out to Apple Support Communities.


These steps may help:


"Set up iPhone to get SMS messages on Mac

You can set up your iPhone so that you can receive and send SMS messages (short text messages) and MMS messages (text messages with graphics, audio, video, and other media) on your Mac. After you set up your iPhone, when you receive an SMS message, it appears 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 message.

The Messages window with several conversations listed in the sidebar at the left, and a transcript showing at the right. The message bubbles are green, indicating they were sent as SMS text messages.

Important: To receive and send SMS and MMS messages on your Mac, your iPhone must have iOS 8.1 or later, and your iPhone and Mac must be signed in to iMessage using the same Apple ID. See the Apple Support article Use Continuity to connect your Mac, iPhone, iPad, and Apple Watch.


  1. On your iPhone, go to Settings > Messages.
  2. Tap Text Message Forwarding.
  3. Note: If you don’t see Text Message Forwarding, make sure you’re signed in to iMessage using the same Apple ID on both your iPhone and your Mac.
  4. Turn on your Mac in the list of devices.
  5. If you’re not using two-factor authentication, a six-digit activation code appears on your Mac; enter this code on your iPhone, then tap Allow."

If you are still having issues, can you provide a few more details? Are you having issues with SMS, iMessage, or both? When did you first notice this? Also, which iOS version do you have on your iPhone?


Cheers!
