Mail is not working after upgrade to El Capitan

I just upgraded my system - MacBook Pro (13-inch, Mid 2012) 2.5 GHz Intel Core i5 SSD 500GB Drive running Mavericks to the El Capitan version 10.11.6 (15G1004).

Now -

1. MacMail is not working after upgrade - Menu bar shows, no window visible.

2. MacMessages is not working - Menu Bar shows, no window visible.

3. System will sometimes "Crash" or will "Restart" randomly.


Does anyone have advice to solve these problems?

Hello ArciMacBook,


Thank you for using the Apple Support Communities. I know having an issue with your Mac after updating to El Capitan is not what you expect. If I understand you correctly, after updating you're having an issue with Mail, Messages and restarting unexpectedly. I would use these steps to resolve these issues and get your Mac working properly again.


1. Try running First Aid on your hard drive with the built in Disk Utility tool, as this can correct simple issues like you're experiencing. Then restart your Mac and test Messages and Mail again.

2. Use "safe mode" to start up your Mac so that it performs certain checks, delete system cache files, verifies your startup disk, and attempts to repair directory issues if needed. Log into your user account in safe mode and test Mail and Messages. Then restart your Mac normally and test again.

3. You can figure out if unexpected behavior is related to a user file or setting by trying to reproduce the issue from another user account. This process includes creating a new user account, logging in to it, and testing for the issue.
