By Carrie Murray, Monday, December 24, 2018

iMessage allows users to send and receive messages over Wi-Fi among different iOS devices and Mac computer. In general, if you log in the same Apple ID on iPhone and Mac, the iMessages will sync between them. But many users find that after updating iOS to the latest version, especially iOS 11 and above, the iMessage on Mac is not syncing. If you also meet the same situation and wonder how to refresh iMessage on Mac, read on to learn the quick solutions we offer for you.

1. Fix iMessage Not Syncing on Mac from iPhone

When iMessage is not syncing between iPhone and Mac, you should check your iMessage settings both on Mac and iPhone. Let's get started with iPhone first.

On Mac, iMessages are sent and received based on your Apple ID (the iCloud email address). To let iMessage updating on Mac, first you can need to make sure that iMessage can be sent and received by both your phone number and Apple ID on iPhone. The iMessage not syncing on Mac happens when you set the iMessage to send based on the phone number but not the Apple ID on iPhone.

  • Open Settings. Scroll down and tap on Messages.

  • Choose Send & Receive.

  • In the "YOU CAN BE REACHED BY IMESSAGE AT" section, check the phone number or email address you use to send and receive iMessages.

  • Go to Settings > Messages.

  • Toggle off iMessage on the top. After several seconds, toggle it on.

Turn on iMessage

Send an iMessage to your friend and check if the message threads show up on Mac now or not.


2. Fix iMessage Not Syncing on Mac from Mac

If iMessage on the Mac is still not updating after the adjustments on iPhone, you may check the settings on Mac.

To make sure iMessage showing up on Mac, you should re-enable your Apple ID account on Mac.

  • Open iMessage > Preferences.

  • Head to the Accounts section.

  • Make sure the Apple ID you sign in on the Mac is the same as the one on iPhone.

  • Check "Enable this account" and check the email address of your Apple ID.

Now, try to send an iMessage on iPhone and check whether it syncs on Mac.


3. Confirm Phone Number with Apple ID
