Why is my iMessage not synchronized between iPhone and Mac?

Synchronization problems can occur for a variety of reasons. Here are some of the most likely reasons:

• Connection issues

A weaker internet connection may cause your information to be unsynchronized. Both your Mac and iPhone require stable Wi-Fi or cellular connections to stay synced.

• iCloud Sync Settings

iCloud settings are another common reason why information is out of sync on Mac. If your iCloud or iMessage settings are misconfigured, your information may be blocked from synchronizing between devices.

• Apple ID mismatch

Your device needs to be connected to the same Apple ID. If not, the information will not be properly synchronized.

How to fix iMessage out-sync issue on Mac

Getting your iMessage synced correctly can be a bit cumbersome, but following the steps below can usually solve the problem.

1. Check your internet connection

Unlike older SMS, iMessage requires a stable internet connection to be delivered between one device and another. For security, just turn Wi-Fi off and turn on. I also recommend that you use WiFi Explorer to scan:

1. Download, install and open WiFi Explorer on your Mac.
2. Find your network name in the list and click it.
3. Go to Network Details and check Signal Quality.
4. Checking the "channel" can also be useful - just to make sure you are not sharing channels with too many other networks.

2. Exit iMessages and try again

Sometimes, simply log in again to resolve the “Information Out of Synchronization on Mac” issue.

On your Mac:

1. Go to Information > Settings in the menu bar.
2. Click the iMessage tab, and then click Log Out.
3. Sign in again with the same Apple ID.

On your iPhone:

1. Go to Settings > Messages.
2. Tap Send & Receive and log out.
3. Log in again and check if iMessages is syncing.

3. Check whether the information in iCloud is enabled

How to refresh information on your Mac? If iCloud is turned off, iMessage will not be synchronized. So you need to check if it is enabled on all devices. Please follow these steps:

On your Mac:

1. Open the Message Application.
2. Go to Message in the menu bar > Settings > iMessage.
3. Check Enable information in iCloud.

On your iPhone:

1. Go to Settings > Apple ID.
2. Touch iCloud > Messages. You may need to touch Show All.
3. Open "Information in iCloud" to synchronize.

4. Manually synchronize information

Manual synchronization can also force your information to be updated quickly.

I prefer using a content transfer application called AnyTrans for iOS. With its help, you can sync your information across devices—all or only certain information. Here is how it works:

1. Download, install and open AnyTrans for iOS on your Mac.
2. Use a cable to connect your iOS device to your Mac.
3. Once your phone content appears in AnyTrans for iOS, select "Information".
4. Select the information you want to move from iPhone/iPad to Mac.
5. Click to Mac.

Tip: If you are also a WhatsApp user, please check out ChatMate for WhatsApp. This is a convenient app that enhances your WhatsApp desktop experience, offering custom notifications, privacy mode, and the ability to stay connected without using a browser. It's a great companion for anyone using both iMessage and WhatsApp on a Mac.

5. Check your email address

Surprisingly, how mismatched email settings messes everything up and leaves you wondering, “Why is my iMessage out of sync between iPhone and Mac?” So double check to make sure you use the same contact information on all devices.

On your Mac:

1. Open the Message Application.
2. Go to Message in the menu bar > Settings > iMessage.
3. Verify the address under "You can receive information through the following methods".

On your iPhone:

1. Go to Settings > Messages.
2. Tap Send & Receive.
3. Make sure you have selected the same email address and phone number for sending and receiving messages on both devices.

Tip: I love iMessage, but sometimes it feels like I keep switching between apps to keep up with everyone. This is a little too much! That's why I started using IM. It's very useful because it allows me to put all my chats (like WhatsApp, Skype, Slack, etc.) in one app. In addition, it has features that make my life easier. I like being able to share files and set custom notifications for work or home. Try it too.

6. Confirm your phone number and Apple ID

Your contact information is outdated or incorrect, and can also affect sync and cause iMessage to be unable to be updated on your Mac. Verify that your phone number is accurate and matched.

On your Mac:

1. Open the Message Application.
2. Go to Message in the menu bar > Settings > iMessage.
3. Check that your phone number is listed and confirm.

On your iPhone:

1. Go to Settings > Messages.
2. Tap Send & Receive.
3. Make sure your mobile number is listed and confirmed.

7. Update your device

Sometimes, problems that text messages do not appear on your Mac will disappear due to software failures. Apple may have fixed it in a recent update, so it's best to check if you have it installed;

On your Mac:

1. Go to the Apple menu > System Settings.
2. Click General > Software Update.
3. Click Update Now or Restart Now and wait for the update to install.

On your iPhone:

1. Go to Settings > General.
2. Tap Software Update.
3. Tap Update now.

These steps often help resolve iMessage synchronization issues.
