How to Fix iMessage Not Syncing on Mac?

Searching for effective ways to fix iMessage not syncing on Mac?

It can be frustrating when an app doesn’t work as intended. Case in point: iMessage. It’s a great messaging tool that allows users to send and receive messages between their iOS and Mac devices. But sometimes, iMessage doesn’t sync on Mac.

Several culprits could be behind this issue. These include updating to the latest iOS 14 and other newer versions. There could also be random bugs on any of your devices. Another possible cause is unmatched Apple ID. Nevertheless, Saintlad is here to help.

We understand how frustrating it is to face tech issues. That’s especially true when you need to send or read a time-sensitive message. So in this article, we list several troubleshooting methods. Here’s how to fix iMessage not syncing on Mac.

Let’s get started!

1. Turn iMessage Off and On.

Since the issue is about syncing, you need to refresh the connection between two devices. One way to do that is to re-enable iMessage on your iPhone and Mac. 

Here’s how to do it:

  1. On your iPhone, go to Settings.
  2. Select Messages.
  3. Then, toggle off the button next to iMessage.

  1. On your Mac, open iMessage.
  2. Pull down the Messages menu. Then, click Preferences.
  3. Go to Accounts. Under Apple ID, uncheck Enable this account.
  4. Wait for a few minutes before turning iMessage back on both on your iPhone and Mac.

After this, open iMessage on both devices. See if the messages finally synced. 

2. Check and Adjust iMessage Settings.

You need to log in using one Apple ID to make iMessages automatically sync between your iPhone and Mac. That’s what happened when you first set it up. But a software update or random bug could change your iMessage settings. Hence, the disconnect.

If re-enabling the iMessage on both devices didn’t work, it’s time to check your iMessage settings. See if anything has changed without your knowledge. And if there is, restore it to your original settings. This could fix iMessage not syncing on Mac. 

Here’s how to check your iMessage settings on your iPhone:

  1. Launch Settings.
  2. Select Messages.
  3. Tap Send & Receive.

Here’s how to do it:

  1. Go to

After a software update or due to a random bug, some settings might have changed on your iPhone. These can include your settings for message forwarding. So it pays to check this feature and make sure it’s enabled for the Mac you’re using right now.

Here’s how to do it:

  1. On your iPhone, navigate to Settings.
  2. Tap Messages.
  3. Scroll down to find and tap Text Message Forwarding.
  4. Assuming you use the same Apple ID on both your iPhone and Mac, you will see the name of your Mac on the list of devices that can send and receive text messages from the iPhone. Make sure the toggle button beside your Mac is on.
