Q: Mail won't open since upgrade

Can anyone help me please?

 

Since upgrade to Sierra 10.12 my Mail app has completely stopped working. I just get a message advising that Mail upgrade is taking place with an option to read about the new features. Seems to be stuck.

 

Thanks for your help! Not impressed so far.

Fix Sierra Installation

 

Try each of these in order. Test to see if the computer is working properly:

 

  1. Reset the PRAM
  2. Reset the System Management Controller (SMC)
  3. Start the computer in Safe Mode, then restart normally. This is slower than a standard startup.
  4. Repair the disk by booting the from the Recovery HD. Immediately after the chime hold down the Command and R keys until the Utility Menu appears. Choose Disk Utility and click on the Continue button. Select the indented (usually, Macintosh HD) volume entry from the side list.  Click on the First Aid button in the toolbar. Wait for the Done button to appear. Quit Disk Utility and return to the Utility Menu. Restart the computer from the Apple Menu.
  5. Reinstall OS X by booting from the Recovery HD using the Command and R keys. When the Utility Menu appears select Reinstall OS X then click on the Continue button.
