• iMessage is turned off on your device or on your recipient’s device. To check if iMessage is turned on for your device, go to Settings > Messages > iMessage.
• iMessage is temporarily unavailable on your device or on your recipient’s device.

If you receive messages on one device but not the other

If you don't see your phone number, you can link your iPhone number to your Apple ID so you can send and receive iMessages from your phone number. You can also set up Text Message Forwarding so you can send and receive MMS and SMS messages on all of your Apple devices.

If you have issues with a group message

If you’re in a group message and stop receiving messages, check if you left the conversation. Open Messages and tap the group message. If you see a message that says you left the conversation, then either you left the conversation or you were removed from the group message. You can rejoin a group message only if someone in the group adds you.

To start a new group message:

1. Open Messages and tap the Compose button to start a new message.
2. Enter the phone numbers or email addresses of your contacts.
3. Type your message, then tap the Send button .

1. Open Messages and find the conversation that you want to delete.
2. Swipe left over the conversation.
3. Tap Delete.

When you delete a message, you can't recover it. If you want to save parts of a message, take a screenshot. To save an attachment in a message, touch and hold the attachment, tap More, then tap Save.

In this article, we will be discussing how you can fix the problem of the iMessage not syncing between the Mac and iPhone.

The iMessage is a great messaging tool for Apple users, as it allows them to send and receive messages between all iOS and Mac devices. You would just need to log in using one Apple ID to multiple devices and the iMessages will automatically sync across all devices.

However, there will be cases where the iMessage will not be syncing between Mac and iPhone, making it hard for you to access your iMessage when you switch devices. This could for a number of reasons but mostly it happens after updating the device to iOS 14 or newer.

Part 1. What to Do When iMessage is Not Syncing Between iPhone and Mac

There are a lot of ways for you to deal with this problem and we will be discussing some of them here.

1.1 Turn On and Off iMessage to Fix iMessage Not Syncing on Mac

The first solution is the simplest one, considering that you just updated your device, maybe a simple rebooting of the iMessage tool can do the trick.

Here’s how to do it:

1. On the iPhone
2. Go to Settings > Messages
3. Turn off iMessage
4. On the Mac
5. Open iMessage app
6. Click on Messages > Preferences > Accounts
7. Uncheck the Enable Account under the Apple ID

Wait for a few minutes then turn the iMessage back on both devices and see if that has done the trick. If not, then you can try the next solution.

1.2 Double Check the Settings of your iMessage and Apple ID

It is possible that the settings of your iMessage have changed after your update, so it is best to double check them to see if anything has changed.

Here’s how you will do it:

1. On the iPhone
2. Go to Settings > Messages
3. Go to Send & Receive
4. Make sure that your Apple ID is there

Make sure that the right mobile number and email is appearing under the “YOU CAN BE REACHED BY MESSAGE AT” and “START NEW CONVERSATION FROM”

If not, edit it and input the right details

1. On your Mac
2. Open the Messages app
3. Tap Messages > Preferences
4. Click Accounts

Make sure that the correct email and phone numbers are displayed under the “YOU CAN BE REACHED BY MESSAGE AT”

If not, edit it and input the right details

1.3 Check your Apple ID

Using your Mac, open the Apple ID website and sign in to your account

Go to Reachable At

Confirm that your Apple ID is listed there, as well as your mobile number

If not, edit it and input the right details

If everything turns out okay, or if the correct information has already been edited, reboot your iPhone and Mac and see if the messages have already synced.

1.4 Try Using the Device that is not syncing to send out Messages

It is possible that one of your devices is just delayed when it comes to updating, so using that device can also trigger an update of the messages.

Here’s how to do it:

Check which among your devices is not updating properly

If it is your iPhone, try sending a message using your iPhone, if it is your Mac, then use the Mac to send messages

Once the message has been sent, this will usually prompt the device to start updating the messages, thus syncing your iMessage properly across all devices.

Now, if all the solutions above still didn’t work, then you might want to try looking for a different solution to fix the problem. Luckily, FoneDog Mobile Solution Provider has a way to solve the problem, and that is with the help of their iOS Data Backup and Restore.

Greetings. Nice post, thanks. My problem with syncing of iPhone and iMessage (Mac) is only for two specific correspondents. That is, sync works very well for almost all my contacts. But for two, it fails. I've double-checked that the contact mobile #s are the same on both devices. Indeed, both used to sync, and now they don't. Any thoughts?
