How to Fix iMessage Syncing Issues

While iMessage is one of the most-used services for iOS users, it’s definitely not without its problems. Here’s how to fix iMessage syncing issues between your iOS and OS X devices.

iMessage has changed the way that many people communicate with their family and friends on a daily basis. With iMessage being available on all of your iOS devices, it makes it even more convenient to use.

We’ve discussed many common problems with Apple products in the past, but iMessage is something that deserves some special attention, considering that many users come across all sorts of problems with the messaging service on a regular basis.

One of the biggest issues that we’ve seen with iMessage is syncing the service across all of your various Apple devices, including iOS devices and Mac computers running OS X. Sometimes, there are many problems that can arise when dealing with multiple devices and getting iMessage synced across all of them.


If you’ve been having this kind of trouble with iMessage lately or are just preparing for those inevitable problems to arise, read on to learn how to fix iMessage syncing problems.

Set Up iMessage Correctly

It’s possible that you didn’t set up iMessage properly, which could be why the service may not be syncing up correctly.

iMessage should sync up with all of your Apple devices together as long as all of them are signed in under the same Apple ID, but surprisingly, it doesn’t work that smoothly sometimes. Follow these steps to properly set up iMessage.

  • On your iPhone and/or iPad, open up the Settings app.
  • Tap on Messages.
  • Tap on Send & Receive.


  • Make sure your email address shows up at the top next to Apple ID. If not, tap on this and sign in with your Apple ID.
  • Also, make sure your main phone number is selected under the section titled Start New Conversations From.

Repeat these steps on all of your other iOS devices. This will allow you to send and receive iMessages not just between your iPhone and Mac, but you’ll be able to add in an iPad that you might have lying around as well.

To set up iMessage on Mac, follow these simple steps.

  • Open up the Messages app.
  • Click on Messages in the menubar in the top-left corner and then select Preferences (or just hit Cmd + comma on your keyboard).
  • Next, click on the Accounts tab and you should see your Apple ID email address in the sidebar. If not, click on the + sign at the bottom and add your Apple ID.


  • Once added, click on it and you’ll see some similar settings that you did on your iOS device. Simply make sure that Enable this account is checked, along with your phone number further below.
  • At the bottom of the Preferences pane, make sure your phone number is selected from the dropdown menu under Start new conversations from.

After that’s set up, you should be good to go, and any iMessages you receive on your iOS device will also show up on your Mac, and vice versa. However, if you’re still having problems, there’s a quick fix.

Turn Off iMessage & Turn It Back On

If you set up iMessage correctly but are still coming across syncing issues, there’s a quick fix that you can perform to sort of reset iMessage and knock it back into proper position.

Essentially, you’re just disabling iMessage on all your iOS and OS X devices that have iMessage, and then re-enabling it on each device one at a time.


To do this on your iOS devices, go to Settings > Messages and toggle iMessage off on all of these devices. On Mac, you’ll open up Messages and then click on Messages > Preferences > Accounts. From there, uncheck Enable this account and close out of Messages and then open it back up.

At that point, go back to your iOS devices and re-enable iMessage, and then head to your Mac and do the same thing. Give it a few minutes for your devices to communicate with each other and eventually iMessage will be ready to go. From there, you shouldn’t have anymore problems.
