Apple mail this message has no content mac

A classic issue!

When you try to send an email from Apple Mail on a Mac, but the message has no content, it's usually because the email composer window is not visible or is not focused. Here are a few troubleshooting steps to help you resolve the issue:

1. Check the email composer window: Make sure the email composer window is open and visible. You can do this by clicking on the "Compose" button in the top left corner of the Apple Mail window or by using the keyboard shortcut Command + Shift + E.
2. Focus on the email composer window: If the composer window is open but not focused, try clicking on it to bring it to the front. You can also use the keyboard shortcut Command + Tab to switch between open windows and select the email composer window.
3. Check for any hidden windows: Sometimes, a hidden window can cause issues with the email composer. Press Command + Shift + H to hide all windows, and then press Command + Shift + H again to show all windows. This might help you identify any hidden windows that are interfering with the email composer.
4. Restart Apple Mail: If none of the above steps work, try restarting Apple Mail by quitting the application and relaunching it.
5. Check for any conflicts with other apps: If you have other apps open that are using the same keyboard shortcuts or window layouts, it might cause conflicts with Apple Mail. Try closing any other apps that might be interfering with Apple Mail.
6. Reset Apple Mail: If none of the above steps work, you can try resetting Apple Mail by deleting the com.apple.mail.plist file. To do this, follow these steps:
   • Go to the ~/Library/Preferences folder (you can use the Finder's "Go" menu to navigate to this folder).
   • Find the com.apple.mail.plist file and delete it.
   • Restart Apple Mail.

If none of these steps resolve the issue, you can try searching online for more specific solutions or reaching out to Apple Support for further assistance.
