If you're here, you probably need help with Mac Mail. Email is a crucial part of online communication, whether for work or personal reasons. When your Mac Mail stops working after the macOS Tahoe update, it can be frustrating. You might experience Mail not responding, Mail not loading content, Mail not sending emails, but still receiving them, or other unusual issues.

In this guide, we'll dive deep into Mac Mail not working, explore its causes, and provide detailed troubleshooting steps to get your email flowing smoothly again.

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

As an integrated app pre-installed on macOS, the Mail app should work correctly. So what causes Mail not to work? Here are some common reasons:

• Mac Mail may experience glitches after a macOS update due to compatibility issues.
• Poor or unstable internet connections can prevent Mail from sending, receiving, or loading emails.
• Incorrect Mac email settings can prevent the Mail app from functioning properly.
• Running an outdated version of macOS can cause compatibility issues with Mail.
• Occasionally, third-party apps or plugins may interfere with Mail.
• The Apple Mail server may be down.

Basic Troubleshooting for Mac Mail Not Working on macOS Tahoe

Before diving into scenario-specific solutions, try these basic troubleshooting steps—they often solve the problem quickly:

1. Restart your Mac or the Mail app to clear temporary glitches.
2. Check the Wi-Fi icon in the top-right corner of your screen. Is your Mac connected to a stable internet connection?
3. Ensure your macOS and Mail app are up to date. If not, follow our guide on updating macOS.
4. If you have Mail plugins installed, temporarily disable them to see if they are causing the problem.

If these steps don’t resolve the issue, move on to scenario-specific solutions.

Case 1: Mac Mail Not Opening on macOS Tahoe

If Mail keeps loading but doesn’t open, try these steps:

1. Force-quit the app: Press Command + Option + Esc, select Mail, and click Force Quit. If this fails, restart your Mac.

2. Check the Mail app location:
   • Open Finder and go to the Applications folder. Locate Mail.

     

   • If missing, press Command + Space, type "Mail" in Spotlight, and locate the app.
   • Drag it back into the Applications folder.
   • Restart your Mac and try opening Mail again.

Case 2: Mac Mail Not Sending or Receiving Emails on macOS Tahoe

Issues with sending or receiving emails often relate to SMTP (sending) or IMAP (receiving) settings:

1. Open Mail > Mail menu > Preferences.
2. Click the Accounts tab and select your email account.
3. Check IMAP and SMTP settings under Server Settings.

   

4. Ensure the server address, username, and password are correct.

If problems persist, remove and re-add your email account:

1. Under Accounts, click the minus button to remove the account.
2. Click the plus + button to re-add it, filling in all required information.

   

Case 3: Mac Mail Not Loading Content on macOS Tahoe

Mail may fail to load content due to an unstable internet connection. Check Wi-Fi first.

Rebuilding your Mailbox can also help if emails are missing, garbled, or not displaying correctly: Mail > select the mailbox > Mailbox > Rebuild. This downloads messages again from the server.

Check Apple’s server status if issues persist, especially for iCloud Mail: Apple System Status.

Case 4: Mail App Crashing on Mac (Tahoe)

If Mail crashes, try force-quitting and refreshing the app:

• Reload Mail: Press Command + Shift + R.
• Or: Mail > Mailbox > Synchronize for each account.

  

Case 5: Slow Mail Performance on macOS Tahoe

To improve performance:

• Rebuild your mailbox.
• Clear old emails.
• Use a professional Mac cleaner to remove junk files, duplicates, and caches.
