While we usually communicate through our smartphones, there is a convenient feature that allows us to continue existing conversations and even initiate new ones directly from our Mac. This feature is one of the main advantages of using iMessage within the Apple ecosystem.
If you are encountering issues with sending or receiving iMessage on your Mac, there’s no need to worry. I have some useful solutions that can help resolve the problem and restore the smooth functionality of your iMessage.

1. Check if the recipient has iMessage
Before getting frustrated about iMessage not working on your Mac, ensure that the recipient you’re trying to message has iMessage. iMessage is only compatible with Apple devices that have iMessage activated.
To troubleshoot the issue, try sending messages to a few individuals with whom you have previously communicated via iMessage. This will help determine if the messages go through successfully. If the problem is isolated to a specific contact and you can’t send messages to them, the issue may be on their end. However, if you are unable to send messages to any of your contacts, the problem likely lies with your device.
Another step to take is to check whether the issue is specific to your Mac or if it affects your other Apple devices as well. Test iMessage on your iPhone, iPad, or any other Apple device you have to see if the problem persists across multiple devices. This will help determine if the issue is isolated to your Mac or if it is a broader problem affecting your Apple ecosystem.
2. Check your internet connection
One common oversight when troubleshooting iMessage issues on a Mac is checking the internet connection. It may seem obvious, but many users overlook this step. A poor or unstable internet connection can often be the underlying cause of problems with iMessage. Therefore, make sure to verify the stability and quality of your internet connection when experiencing issues with iMessage on your Mac.
Before proceeding with more advanced troubleshooting steps to fix iMessage not working on your Mac, make sure to confirm that your internet connection is reliable and strong. A stable and robust internet connection is essential for the proper functioning of iMessage.
If you are using your iPhone’s hotspot to connect your Mac to the internet, it is advisable to avoid constantly switching between your iPhone and Mac. In my experience, using your iPhone for an extended period of time can lead to your Mac getting disconnected from the iPhone’s hotspot, potentially impacting the performance of iMessage.
3. Check if iMessage is down
Sometimes, Apple Messages can be affected by temporary outages, causing issues with its functionality. To check if iMessage is experiencing widespread problems, you can visit Apple System Status. Look for a green circle next to iMessage. If you notice any other status indicator, it indicates that Apple may be encountering technical difficulties. In such cases, it is advisable to wait until Apple’s technicians resolve the issue.
4. Sign in to the same Apple ID
If you are experiencing a situation where messages sent from your iPhone do not appear on your Mac, or vice versa, the likely cause is related to your Apple ID and iCloud. This is a common problem that arises when individuals have multiple Apple ID accounts or when devices are shared among users.
- To check which Apple ID account is signed in on a device, click the Apple menu → System Settings.

- Check the Apple ID signed in at the top of the sidebar to ensure it is the correct one for both your iPhone and Mac. This is important for proper message synchronization between devices.

Additionally, if you are using both an iPhone and a Mac, make sure that Message Forwarding is enabled. This feature allows your Mac to send and receive messages through the Messages app. Enabling Message Forwarding ensures seamless communication between your devices.
To enable it, do the following on your iPhone:
- Go to the Settings app → Messages.
- Select Text Message Forwarding.
- Find your Mac’s name and toggle it on.
5. Check if iMessage is enabled
It is also possible that there are no issues with Messages, but your Mac is not configured to receive iMessages. To enable iMessage on your Mac, follow these steps:
- Open the Messages application on your Mac.
- While the Messages window is active, click on the “Messages” option in the menu bar.
- Click on “Preferences” in the “Messages” menu, and then select the “iMessage” tab in the Preferences window that appears.

- Ensure that the “Enable Messages in iCloud” option is checked. This ensures that your messages are synchronized with iCloud. If this option is disabled, your messages will be downloaded only to your device, and they won’t be synced across your Apple devices.

6. Check Time Zone settings
Your Mac arranges messages in your chat history according to their timestamps. As a result, if it mistakenly identifies a message as being from an earlier time, it might place it further back in your conversation history, even if it was meant for the current moment. This can result in recent messages appearing to be missing.
This issue frequently occurs when the time zone is not set to update automatically. If you receive notifications of new messages but don’t see them in your conversation thread, this could be the underlying cause. Here’s how you can resolve it:
- On your Mac, click on the Apple menu located in the top-left corner of the screen.

- From the sidebar of the Apple menu, choose “General.” Then, select “Date & Time” from the options provided.
- Ensure that the option “Set date and time automatically” is checked.

7. Restart your Mac
It is not uncommon for the Messages app on Mac to become unresponsive, and a quick restart can often resolve the issue. Start by closing all open applications, including Messages. Then, follow these steps:
- Navigate to the Apple menu and select “Restart” to initiate a system restart.

After your Mac finishes rebooting, relaunch the Messages app and check if the issue has been resolved.
8. Update your OS
If restarting your Mac did not resolve the issues, the next step is to check if your device is up to date with the latest system software update. Updating to the most recent operating system ensures optimal performance and fixes any known glitches or bugs that may be causing problems with the Messages app.
- To check for system software updates, click on the Apple menu and select “System Preferences” from the drop-down menu.
- In the System Preferences window, click on “General” and then choose “Software Update.”

- If there is an available update, click on the “Update Now” button to initiate the update process.

9. Try a different way of sending and receiving messages
If iMessage is still not functioning properly, verify the phone number or email associated with your Apple ID account and check if you are using the correct option. Consider trying an alternative phone number or email linked to your Apple ID to see if that resolves the issue.
- On your Mac, open the Messages application and then click on “Preferences” in the “Messages” menu. In the Preferences window, select the “iMessage” tab.
- In the iMessage tab of the Messages Preferences window, you can enable or disable your email or phone number associated with your Apple ID. Try toggling the options on or off and observe if this resolves the issue and gets iMessage working again.
10. Clear Messages cache
Similar to other applications, Messages also stores data and files known as caches. Over time, these caches can accumulate and potentially impact the app’s performance. Deleting the cache can help improve the app’s responsiveness and resolve existing issues.
Please note that clearing the cache for iMessage will result in the loss of your message history on all your devices. Here is the process to clear the cache:
- Quit the Messages app on your Mac.
- Open a Finder window and click on “Go” in the menu bar.
- Press Cmd + Shift + G.

- In the dialog box, enter the following path: ~/Library/Messages/

- Delete files in the following Messages folders: chat.db-wal, chat.db, and chat.db-shm.

- Empty your Trash.
11. Sign out and sign back in on iMessage
Another troubleshooting step is to sign out and then sign back into iMessage, which can help resolve issues and restore proper functionality. Follow these steps to sign out and sign back into iMessage:
- Open the Messages app on your Mac.
- In the menu bar, click on “Messages”.

- Select Preferences from the dropdown menu → go to the iMessage tab.

- Press Sign out next to your Apple ID.

- Once you’ve signed out, sign in back again using your Apple ID credentials.
