If any of these don’t help then here are some methods that can help you solve the problem.

1) Check The Account Settings In iMessages

The account settings on the Mac basically maintains the right connection between the messaging data and the messages application that is connected with your phone number, Apple ID and your iCloud account. There are simple steps that might help solve the problem of messages not working on Mac. You just need to follow them.

First of all, on the home screen of your Mac, you will find messages. Click messages and then select Preferences. However, you will have to make sure you have logged in your Apple account on your Mac Book. Your Mac is required to be logged in to an Apple account if not, you would not be able to receive any messages.

In case you want to check the login status, you will then have to select ‘Accounts’ in the preferences. While checking the accounts settings, also make sure to check the email address where you can be reached.

Then, at the bottom of the screen, you will see ‘Start new conversations from’, select it. It will show you your available contact point list. To make sure duplicate messages are not created, check that the devices that have been logged on to iCloud have the same options available. It is preferred to use your mobile phone number.

If your device is properly logged in but you are still facing issues with syncing then scroll down. You will find the iCloud sign-in-step. Select it and then delete your existing account and sign in again. Make sure that you follow the steps carefully.

2) Force Quit The Messages App And Open It Again

Usually, when the issue occurs it is reported that a red alert exclamation mark appears on the screen as a symbol that the message is not sent and there is some issue that needs to be fixed. It is a warning which needs to be considered.

Force quit message app and then re-open it. Quit or cancel any setting option that appears on the screen and shut down the message app menu.

Here is another way to do this

Choose ‘Force Quit’ from the Apple menu bar that is on the top of the extreme left of the screen. And then select ‘Messages’ from the new menu that shows up. After this click force quit. It will close all the options and your application. Now re-open the messages app and here you are free to send messages from Mac.

3) Toggle iCloud Sign-In

Go to settings, select the message and toggle iMessage off.

Go back and return to the previous menu again and toggle iMessage on from the settings.

If this does not help then you need to sign out from your iMessage and sign in back to your Apple ID. There should be a few seconds’ gaps between the sign in and sign out a step so the system is able to accept the command accurately. This is the time when you can decide to switch to another apple id which you are sure will not cause your problem in the future.

4) Clear Messages Cache

One of the fact about Mac’s message app is that it saves all the text messages and its history which contains its basic information like sending and receiving time. Unfortunately, there is no automatic feature of automatically deleting messages from the app so here is where manual effort is required.

Clearing cache will empty the space of all the unwanted chats and data that have been saved in your account as back up and you really do not need it.

Here is a quick fix to this problem

  • Messages should be enabled on iCloud on your Mac.
  • Change your Message App Preferences to keep messages as back up for a specified time which can vary from 1 month to 1 year. This will be your personalized setting.
  • If you want to delete an entire conversation do it by pressing
    Command + Delete or there is another way by selecting Delete Conversation option from the File bar.
  • Delete selections from message threads by holding the
    right-click press and choosing Delete or going to Edit > Delete from the slide bar.
  • There is an option to keep the conversation open but it will be content free. To delete the content you need to choose
    Edit > Clear Transcriptor Option + Command + K
  • In case if you do not want your Mac to store your message history you need to update your Message App Preferences and un-tick the box for
    ‘Save history when a conversation is closed’
  • Use Terminal to delete your Messages App chat history permanently

Deleting the messages will clear the cache and there will be more space for the new messages to save. Since the storage box for messages on Mac if it won’t be spacious there are chances that you are not able to send any further messages.

5) Restart your Mac

Restarting your Mac book is the simplest solution to this problem. It is the only solution that clicks one’s mind when they face this problem.

You just have to simply click the Apple Menu from the top left corner of the screen and select the seventh option from the bar which says ‘Restart’ and restart the Mac system. This will refresh the system and fix any issue automatically.

At times, our system gets stuck because of being used for a good figure of hours. The system needs a break so it stops responding and that is the time where you need to restart your Mac book so it functions properly. It is the much-needed break for the system before it is ready to function again for hours.

6) Check Date & Time Settings

The date and time setting of our apple device can be another reason for this troubleshooting. Yes, it sounds a bit unusual but any unnecessary change in the date and time of the laptop can cause problems anyhow.

To resolve the date and time problem you need to fix its settings. Start with clicking the Apple Menu, then go to System Preference and select Date and Time option from it. From the next options select the Time Zone tab and then you have to click the ‘Set Date and Time Automatically’ checkbox. At times it may be already selected in that case you have to uncheck it and wait for few seconds so that it gets refresh and reselect it again. This will automatically reset the date and time of your system depending on your location.

To save these settings you need to enter admin password if you have secured your system with one.

7) Hardware Serial Number Mismatch

Every Mac has a unique serial number, in order to use the message you have to get the serial number registered. Registration is not at all issue in Mac with genuine Apple hardware. The off the shelf parts which are the modified versions in Mac create issues.

In cases where a valid and unused serial number are build-up, they require a check to keep them into working. The process of bringing the Mac into running with those serial number is a lot more than these few lines.

8) Update IOS


Apple usually provides us with amazing updates and we are so attracted to them that we can’t resist updating our IOS version even if we do not need it. Since there are always two ends of the rope so if we are benefited with amazing new features we do have the drawback that is our previous settings do get changed automatically after the update.

So, if your iMessage does not work after an update the best solution to this is to recheck your settings and set them back to the previous settings. Signing out and signing in your apple account may help.

There is another flip of this issue that is at times we need to update our IOS version because our prevision version does not support the Mac so, it enables s from sending iMessages.

9) Repair IOS System

There may be a possibility that Apple’s IOS server is down for your device and it may need maintenance in order to repair it. This repairing process is known as ReiBoot. It is the iOS system recovery software, which repairs our device and makes it function properly without any loss of data.

Reboot lets us repair and fixes our iOS back to normal mode on our own by staying at home. You need to get yourself connected with recovery software and web page with complete details of how the process takes place and how it had previously benefited the user and how productive that software is.

10) Keychain Access

The problem may be caused through some error in the keychain. Keychain is the password development system in macOS, which is developed by Apple. This feature is included in all the subsequent versions of Mac OS.

Follow these steps to fix keychain issue

  • Launch Keychain Access (Launchpad > Keychain Access)
  • Click File and Lock Keychain “Login”
  • Again go to File > Unlock Keychain “Login”, enter your admin password. Enter the password only when you are asked for it.
