11 easy ways to fix Apple Mail not working

Troubleshooting a Non-Functional Apple Mail App: A Comprehensive Guide

A malfunctioning Apple Mail application can be incredibly frustrating. This guide provides solutions for various issues, from crashes and freezes to complete unresponsiveness. Let's explore the fixes.

Before diving into technical solutions, a simple restart often resolves minor glitches. Select Apple menu > Restart. If this doesn't work, continue with the following steps.

1. Verify Internet Connectivity:

A stable internet connection is crucial for email functionality. Test your connection by loading a webpage in your browser or using online internet speed tests. For a deeper analysis, consider using apps like NetSpot or WiFi Explorer (available through Setapp) to diagnose Wi-Fi performance and optimize your network.

2. Force Quit the Mail App:

If the Mail app freezes, use the keyboard shortcut Option Command Escape to force quit it.

3. Close All Apps and Restart Your Mac:

Conflicting apps might interfere with Mail's operation. Close all applications, then restart your Mac using the Apple menu. For efficient app closure, use QuitAll (available via Setapp), which manages both foreground and background processes.

4. Reset the Mail App:

Resetting Mail to its default settings often resolves conflicts and incompatibilities. CleanMyMac X (available through Setapp) provides a safe and effective method:

1. Open CleanMyMac X.
2. Select "Uninstaller" from the sidebar.
3. Choose Mail and click the arrow to reveal associated files.
4. Select "Reset."

5. Clean Up Mail Attachments:

Problematic attachments can cause Mail to malfunction. CleanMyMac X's Mail Attachments module simplifies the removal of local attachment copies, freeing up space and preventing crashes.

1. Open CleanMyMac X.
2. Select "Mail Attachments," scan, review selections, and click "Clean."

6. Rebuild Mailboxes:

Rebuild your mailboxes to address potential corruption:

1. Open Mail.
2. Select a mailbox in the sidebar.
3. Choose Mailbox > Rebuild.
4. Repeat for each mailbox, then close and reopen Mail.

7. Reset Mail Preferences:

A corrupted preferences file can cause issues. Resetting it involves deleting the preference file:

1. In Finder, use Go > Go to Folder.
2. Enter: ~/Library/Containers/com.apple.mail/Data/Library/Preferences and press Return.
3. Move com.apple.mail.plist to your Desktop.
4. Restart your Mac and reopen Mail. If problems persist, restore the file.

8. Disable and Re-add Email Accounts:

If you have multiple accounts, disable them individually to identify problematic ones. If this doesn't work, completely remove and re-add accounts, ensuring you have your login credentials.

9. Remove and Reindex Envelope Files:

A corrupted envelope index can hinder Mail's operation. Remove and reindex these files (or use CleanMyMac X's "Speed Up Mail" function for faster results).

10. Manage Storage:

Low storage can impact app performance. Free up space by deleting unnecessary emails and apps (CleanMyMac X can assist with app removal). Aim for at least 15-20% free storage.

11. Update macOS:

Ensure your macOS is up-to-date to address potential compatibility issues. Use System Settings > General > Software Update.

Alternative Email Clients:

If the above steps fail, consider alternative email clients like Canary Mail or Spark Mail (both accessible through Setapp), offering enhanced features and security.

If all else fails, contact your email provider for technical support. Setapp offers a 7-day trial for access to the mentioned apps and its extensive app library.
