mail suddenly stops and I can't restart it , it always stops
I've tried rebooting in safe mode but that doesn't change it
help?
iMac 27″, macOS 10.14
If still no good Disconnect from the Internet, then start Mail, look for the last rec'd eMail.
Does Mail crash if no internet?
Quit Mail & login to your WebMail in a Browser, if possible delete any later eMails there after the last rec'd one on the Mac.
If you have no POP accounts & they’re all IMAP accounts then in Mail’s Mailbox menu choose Rebuild.
