Why Isn't My Mac Mail Working After Sequoia Update?

As an integrated app that comes pre-installed on the macOS, the Mail app should work just fine. What are the root causes of your Mac Mail not working? Below are some common ones:

• Oftentimes, Mac Mail can experience glitches after updating macOS due to compatibility issues.
• Poor or unstable internet connections can prevent Mac Mail from sending, receiving emails, or loading content.
• If your Mac email settings aren’t configured correctly, the Mail app won't function properly
• Running a too-old version of macOS can lead to compatibility issues with the Mail app.
• Occasionally, third-party apps or plugins may interfere with the smooth operation of Mac Mail.
• The Apple Mail server may be down.

Basic Troubleshooting to Mac Mail Not Working on macOS Sequoia

Before diving into more advanced solutions that cater to each scenario, it's always a good idea to try some basic troubleshooting steps. These simple fixes may solve your problems easily.

1. A simple reboot to the Mac or the Mail app can clear out temporary glitches.
2. Check the Wi-Fi icon on the right corner of your screen. Is your Mac connected to the internet and the connection is stable?
3. Make sure you're running the latest version of macOS and that your Mail app is up to date. If not, follow our guide on how to update macOS.
4. If you have any plugins installed on Mail, try disabling them temporarily to see if they’re the cause.

If you’ve tried all the methods above and none of them worked, it’s time to target specific scenarios and solutions.

Case 1: Mac Mail Not Opening on macOS Sequoia

If you click on Mail but only find it keeps loading and not opening, there are a few solutions you can take to resolve the issue. First, try force-quitting the app by pressing Command + Option + Esc, then selecting Mail from the list and clicking Force Quit. If this doesn't work, the next step is to restart your Mac.

If the problem persists after restarting, the app may have been moved from the Applications folder in the beginning. To make sure it's in the correct location, here’s what to do:

1. Open a Finder window and go to the Applications folder. Look for the Mail app.

   

2. If it’s missing, press Command + Space to bring up Spotlight. Then locate the Mail app by typing the name.
3. Once found, drag the app from its current location back into the Applications folder.
4. After this, restart your Mac and try opening the Mail app again.

Case 2: Mac Mail Not Sending or Receiving Mails on macOS Sequoia

SMTP (Simple Mail Transfer Protocol) is the standard protocol for sending emails. IMAP (Internet Message Access Protocol), on the other hand, is used for retrieving and managing emails from a mail server. When you have issues with sending or receiving messages from Apple Mail, the priority is to check your SMTP and IMAP settings. How?

1. Open the Mail app on your Mac. Go to the Mail menu and select Preferences.
2. In the Preferences window, click on the Accounts tab and select the email account you want to check.
3. To check IMAP Settings, click on the Server Settings tab.

   

4. Ensure that the IMAP and SMTP settings are correct, including the server address, username, and password.

After verifying the settings, try sending and receiving an email to ensure everything is working correctly.

If you continue to experience issues, consider removing and re-adding your email account in the Mail app. This can often resolve configuration problems and refresh your connection to the mail servers.

1. Under the Accounts tab, click on the minus button from the left list. Remove the problematic account first.
2. Re-add it by clicking on the plus + button. Fill in all required info and enable it.

   

Case 3: Mac Mail Not Loading Content on macOS Sequoia

Mac Mail not loading content happens frequently if you are not having a good internet connection. Without an internet connection, new messages won’t appear in your inbox. Without a stable connection, Mac Mail can take a long time to load the full message. Therefore, whenever Mail fails to load the content, first check the Wi-Fi on your Mac and take action correspondingly.

Secondly, rebuilding your Mail updates the list of messages in a mailbox, which helps if your emails are missing, garbled, or not displaying correctly. To rebuild your Mail on a Mac, go to Mail > select the mailbox you want to rebuild > Mailbox > Rebuild. This process will discard messages and attachments stored on your Mac and download them again from the mail server.

In some rare occasions, the issue might not be with the Mail app itself but with Apple’s servers. If you are using iCloud Mail, visit the Apple System Status page and look for iCloud Mail. If it’s green, there are no current issues. If there’s an issue, you’ll need to wait for Apple to resolve it.

Case 4: Mail App Crashing on Mac (Sequoia)

When Mail crashes, it often ends up getting stuck on a certain page you are trying to open. When encountering Mac Mail crashing, the first attempt should be to force-quit the app. Besides, you can try refreshing Mail on Mac to troubleshoot Mail crashing.

To refresh Mail on a Mac, you can reload it by pressing Command + Shift + R, just like any other app. If this shortcut isn’t set up in your Keyboard settings, follow these steps instead:

1. Open the Mail app and click on ‘Mailbox’ in the menu bar.
2. Select Synchronize.

   

3. Choose your account. Repeat these steps for each account.
4. Wait for new messages to load.

Case 5: Slow Mail Performance on macOS Sequoia

To speed up a sluggish Mail app, try rebuilding your mailbox as we mentioned above, and clearing out old emails. If you are looking for professional tips, we recommend using third-party Mac cleaners to remove any junk data, duplicate contents, and accumulated cache generated by Mail.
