Before diving into the solutions, it’s crucial to understand how Mac Mail is designed to work. The application is built to sync seamlessly with various email providers, ensuring that you can send and receive emails without a hitch. Keeping your macOS and the Mail app updated is essential for its smooth functioning.

Common Causes

Software Conflicts

Third-party software or plugins can interfere with Mac Mail, causing it to malfunction.

Outdated macOS or Mail App

An outdated system or app can lead to various issues, including the Mail app not opening.

Incorrect Settings

Incorrect IMAP/POP settings can halt the Mail app from opening.

Internet Connectivity

A stable internet connection is crucial for the Mail app to function correctly.

Advanced Factors

Server Downtimes

Sometimes the issue might be with the email provider rather than the Mail app itself.

Corrupted Mailbox or Profiles

Software corruption can disrupt Mac Mail operations, leading to the app not opening.

Troubleshooting Steps

  1. Check for the Correct Mail App Version Ensure that you are using the most recent version of the Mail app. An outdated version can cause the app not to open.
  2. Internet Connection Use the Connection Doctor feature in the Mail app to check your internet connection. A stable connection is crucial for the app to open and function correctly.
  3. Force Quit and Restart Mail App If the Mail app is unresponsive, you may need to force quit the application. Restarting the app can often resolve minor glitches.
  4. Restart Your Mac Sometimes, other applications running in the background can interfere with the Mail app. Restarting your Mac can often resolve this issue.
  5. Update macOS and Mail App Regular updates can fix various issues, including the Mail app not opening. Always keep your system and apps updated.
  6. Check for Software Conflicts If you’ve recently installed new software or plugins, consider disabling them temporarily to see if they’re causing the issue.
  7. Rebuild Your Mailboxes If the Mail app is not opening, rebuilding your mailboxes can help. This function re-syncs all the messages in your accounts.
  8. Reset Mail Preferences Sometimes, a bug in the file that saves your app preferences can cause the Mail app not to open. Deleting the plist file can resolve this issue.
  9. Remove and Re-add Email Accounts As a last resort, you can remove and re-add your email accounts. This action will delete any emails waiting to be sent, so make sure to back them up first.

Expert Tips

For regular maintenance, consider using cleaning software like MacKeeper. It’s also a good practice to check your email accounts directly with the server to ensure your password is working.


The issue of “Mac Mail Not Opening” can be frustrating, but with the right troubleshooting steps, it can be resolved. Keeping your software updated and understanding the common causes can go a long way in ensuring a seamless email experience. Stay informed, stay updated, and enjoy hassle-free email communication.
