5. Sign out of the iMessage and sign in again

If the iMessage app is still not working, signing out and back in may fix the issue. To Sign out from the iMessage, click on ‘Messages’ in the top of the window and go to the ‘Preferences’. These settings control the Messages app and your messaging data associated with your Apple ID, phone number, and iCloud. Click on the “iMessage” section, which is accessible from the “@” symbol at the top of the screen.

Click on an option opposite your Apple ID titled “Sign Out.”  Once you’re signed out, log back into the Messages app to see if this fixes the issue.

6. Check Settings

Open the Preferences tab again. Then First, you need to make sure your device is enrolled in Messages. Your device needs to be enrolled in Messages in order to receive messages. This means you’ll need to log in to your Apple ID on your Mac. You can check your login status in the “Accounts” tab of the Messages preference window. Make sure you check all the boxes.

If your device is logged in but not syncing properly, scroll down to the iCloud sign-in step. Delete, then add your account back in, but follow the steps carefully.

7. Time Settings

Incorrect time cause many authentication processes failure. This includes Messages. If your time zone is set inaccurately or your clock is manually set to an inaccurate time, you will face problems. This can cause issues from HTTPS failures to cookie loss to one-time password failures, so it’s a good idea to keep your clock in sync automatically. If you disabled it, set your clock to be automatically managed by Apple.

To change date & time, open Preferences > Date & Time and check Set date and time automatically. Apple then uses your location and IP address data to keep your Mac’s local time and system clock in sync.

8. iMessage sound not playing

Check your Mac’s system sound is turned on.

• Open Messages app on Mac > Top Menu “Messages” > “Prefrences” > General > Select Play Sound effect.

9. Hardware Serial Number Mismatch

To use Messages, you need to have a unique and unregistered Mac serial number. If your Mac is genuine Apple hardware, this won’t be an issue at all. In many cases, however, you can generate a valid and unused serial number. There are many of them out there: there are far, far more valid serial numbers than there ever will be Macs of a given generation.
