Hi John, A couple of questions first: A] Is this since upgrading from OS X 10.11.6 to macOS Sierra 10.12? or updating macOS Sierra10.12 to 10.12.3? B] Do you receive any error message as to why Mail quit? C] Have you tried Restarting your MacBook Pro after Mail Quits, then launch Mail right after you restart? I would first suggest you “Try A Safe Boot” To perform a safe boot, follow these steps: 1. Start or Restart your Mac. 2. Hold the Shift key immediately when you hear the startup chime, press the Shift key and hold it down until the gray Apple logo appears on the screen. 3. Release the key when you see the gray Apple logo Your Mac will complete the startup process, which will take considerably longer than usual. You’ll eventually see the words “Safe Boot” on the screen—possibly within the login window, depending on which version of macOS you’re running. 4. Open Mail.app as soon as startup process completes. If rebooting in safe mode solves the problem, you know that some system level process is at fault or that one of the caches disabled by safe mode was corrupted. 5. Restart normally and see if the problem is gone.
