Mail Stopped Woking in Sierra

Installed Sierra on late 2009 27" iMac. Most seems fine but when Mail tries to load, window will not load and none of the navigation menus are available (really, none at all!). Reinstalled Sierra--- same problem. Kind of disappointing to have to spend any time to sort out this basic computer application.

VIN,iMac (27-inch Late 2009), macOS Sierra (10.12)

Try setting up a test account, see if the problem's global, or just related to your account.


CREATE A NEW USER


Go to System Preferences --> Create a New User in Users & Groups.

Switch to the New User by logging out/in or use Fast User Switching.

You can skip signing in with your Apple ID unless you need to test iCloud Mail.


Only default Apple apps will be in the Dock in the new User. Go to Applications to open other apps you might want to test.


Do you still see the issue? If yes,


  • What version OS X were you running prior to upgrading?
  • What type of account(s)? (POP, IMAP, Exchange)
  • What Email Provider? Comcast, Earthlink, Cox, ATT, Yahoo, iCloud, Gmail, AOL, Hotmail (other)
