Next, sit at your computer and launch Messages. Here, select your computer from the list of all devices associated with your Apple ID. But what about your contacts who don’t have iPhones? To text them as well, you’ll need to turn back to your phone and head to Settings, Messages, and then Text Message Forwarding. When you open the Messages app on macOS, you should see that your computer and phone conversations are synced, and your computer will be able to text other iMessage users.
Back on your Mac, you should see a pop-up alert saying your phone number has been added to iMessage. Grab your phone again, open Settings, Messages, and turn on the iMessage toggle switch. If everything looks correct, your next step is setting up iMessage so the app can coordinate with your computer. On your Mac, do the same by opening System Preferences and confirming you’re signed into the same Apple ID at the top of the emerging window. On your phone, check this setup by opening the Settings app and tapping your name at the top of the screen. First, you need to sign both your iPhone and your Mac into the same Apple ID.
