On your iPhone: 

Turn off iMessage by going to Settings > Messages. 

On your MacBook: 

Open the Message app, go to Messages > Preferences > Accounts, choose the account you want to disable, and uncheck the "Enable this account" option under the Apple ID.

After you have disabled iMessage on both your iPhone and Mac PC, wait for a few minutes, then restart iMessage to see if the iMessages Sync properly across your devices. If not, proceed to the next solution.

Way 2: Check Whether you Use the Same Apple ID & Email on your iPhone and Mac

The second method is to verify that you have correctly activated your Apple ID and Email address. Your iPhone and Mac should have the same Apple ID and Email address.

• Go to Settings > Messages > Send & Receive on your iPhone.

  

• Go to Messages > Accounts > Preferences on a Mac.

  

Way 3: Force Restart Your iPhone

You can also try restarting your iPhone. It is a quick and easy technique to help you deal with iMessage not syncing between iPhone and iPad.

iPhone 6s and older:

• Hold down the Side and Home buttons at the same time.
• When the Apple logo displays, quickly release the two buttons.

iPhone 7 and 7 Plus:

• Hold and press the Volume Down and Side buttons at the same time.
• When the Apple logo displays, quickly release the two buttons.

iPhone 8 and up:

• Hold and immediately release the Volume Up button, fast-release the Volume Down button, and then press and hold the Power button until the Apple logo appears.

Way 4: Sync iMessage on Mac Manually

You must manually sync if you still have trouble in iMessages not syncing between iPhone and Mac. It is how.

• On Mac, launch the Messages app.
• In the upper left corner, select Messages. Choose Preferences.

• Slide to access the iMessage menu. Select the Sync Now option.

  

Way 5: Check the iMessage Server

If the iMessage servers have a bad day, you won"t be able to sync messages between Apple devices. You can either use Downdetector to validate the problem.

Apple also has a separate System Status page where you can monitor the status of services in real-time. You may check the iCloud and iMessage status by visiting the page.

Way 6: Delete iOS 17/16 Beta Version

We encountered this problem while testing iOS 17/16 betas on iPhone. Our iPhone was running Apple beta software with new iMessage features, whereas our Mac was still running macOS Big Sur, which had an old and stable Messages app.

Because the Messages apps for iPhone and Mac do not share features, this configuration may cause syncing troubles. On iPhone and Mac, you must delete the beta profile and revert to the stable public version.

Way 7: Send A Message to other Devices that are Not Syncing

One of your devices may be delayed in updating, in which case utilizing that device will also cause a delay in the messages.

Here"s how to go about it:

• Determine which of your devices is not updated.
• If it"s your iPhone, try sending a message from your iPhone. if it"s your Mac, send messages from your Mac.
• Once the message is sent, the device will normally begin updating the messages, properly syncing your iMessage across all devices. If not, try other solutions.

Way 8: Enable Messages in iCloud

Apple"s iCloud service is used to store messages and other cloud-based data. For iCloud, the Messages option is enabled by default. You can, however, disable and enable it. To do so, follow the instructions below:

• Open Messages on your Mac and select the Messages option from the Menu bar.

• Open Preferences and navigate to the iMessage option, then turn off Messages in iCloud.

  
• Enable and restart the iMessage app once again.
