Apple mail mac stop split screen

A common issue!

If you're experiencing issues with Apple Mail not splitting the screen on your Mac, here are some troubleshooting steps to help you resolve the problem:

  1. Check if Split View is enabled: Make sure that Split View is enabled on your Mac. To do this, go to System Preferences > Mission Control, and ensure that the "Allow multiple apps and windows" option is selected.
  2. Restart Apple Mail: Sometimes, simply restarting Apple Mail can resolve the issue. Quit Apple Mail, then relaunch it.
  3. Check for updates: Ensure that your Mac and Apple Mail are up to date. Go to System Preferences > Software Update to check for any available updates.
  4. Disable and re-enable Split View: Try disabling Split View, then re-enabling it. To do this, go to System Preferences > Mission Control, and toggle off the "Allow multiple apps and windows" option. Wait for a few seconds, then toggle it back on.
  5. Check for conflicts with other apps: If you're using other apps that also use Split View, try closing them and see if Apple Mail works correctly. If it does, it might be a conflict with another app.
  6. Reset Apple Mail: Try resetting Apple Mail by going to System Preferences > Mail, clicking on the "Accounts" tab, and selecting "Reset" next to the account you're using. This will reset your email account settings to their default values.
  7. Check for corrupted preferences: Sometimes, corrupted preferences can cause issues with Apple Mail. Try resetting your Mail preferences by going to System Preferences > Mail, clicking on the "Preferences" button, and selecting "Reset" next to the "Mail" option.
  8. Reinstall Apple Mail: If none of the above steps work, you can try reinstalling Apple Mail. Go to the App Store, search for "Apple Mail", and click the "Install" button. This will reinstall Apple Mail and its associated files.
  9. Check for macOS issues: If none of the above steps work, it might be a macOS issue. Try restarting your Mac in Safe Mode or performing a System Restore to see if that resolves the issue.

If none of these steps resolve the issue, you may want to consider reaching out to Apple Support for further assistance.
