Here, I will share the nine best methods to fix iMessage not working on Mac issue:
1. Scan Your Mac for Malware
Although Macs are generally considered more secure than other operating systems, they’re not completely immune to malware. Unwanted software can interfere with system processes and applications, including iMessage. Performing a malware scan can help identify and remove these malicious elements.
Here’s how to run a virus scan on Mac using MacKeeper:
- Download and install MacKeeper.
- Launch MacKeeper and navigate to the Antivirus tab in the left sidebar.

- Initiate an instant virus scan by clicking the Start Scan button.

- If any viruses are detected during the scan, click the Fix Items button to resolve the issues.
- If your system is threat-free, you’ll see a No threats found message. You can tap the Restart button to run the scan again.

- Enable real-time antivirus protection to safeguard your Mac from future threats by clicking the Enable button.

Once you have configured your security settings, MacKeeper will continue to operate in the background, diligently scanning for threats and actively blocking any malicious activity.
What Else Can MacKeeper Do?
Besides scanning your Mac for viruses, MacKeeper can do many other Mac maintenance tasks. You can use it to connect to the internet privately via VPN, remove cache files, and delete login items. Learn more about its features in my detailed Mackeeper review.
