Question: mail won't launch after High Sierra upgrade

Since upgrading to High Sierra I've had really frustrating problems with Mail. I have several e-mail accounts: three g-mail, one Yahoo!, one iCloud, and one "other". These accounts work fine on my iPhone.


After upgrading to High Sierra on my 2016 MacBook Pro, Mail is unusable. When I click on its icon in the dock it starts, but it runs for only a second or two before quitting, with no error or other message--it just disappears.


I have tried deactivating all the mail accounts, in which case Mail seems to start and is stable. I have even deleted all the accounts and re-added them. At best Mail works for a while (like, several hours) but then resumes its unexpected quits.


What's the problem here? Do I have to downgrade to Sierra?


After two decades as an Apple customer, I have *never* had such a frustrating experience with Apple software. It makes me think that Apple is more a luxury accessories company than a computer and software company these days.

MacBook Pro (15-inch, Late 2016), macOS High Sierra (10.13.1)

Answer:
Answer:

Yes, the problem does still occur in safe mode.


Or at least it did; It no longer appears to be happening, in safe mode or out. Odd, because I didn't change anything that I know of.


This is sort of an unsatisfying end to this, but at least it's working.

See the steps in the article Repair a disk using Disk Utility - Apple Support

Also in user library macOS Sierra: Library folder

Delete the contents of Folders Caches , Cookies and saved application state into the trash , restart the computer and empty the trash .

If the issue still persists create a new user account How to test an issue in another user account on your Mac - Apple Support

And configure the mail account Set up Mail with email accounts - Apple Support

Thanks; I did try repairing the disk. No problems were found and it didn’t solve the problem. I didn’t try deleting anything from Library, as I assumed deleting all the mail accounts and starting over would have done that.


Anyway; like I said I’m not sure why it’s working now, but at least it’s working.
