Q: Mail crashes when importing MBOX files
Mail crashes instantly when I select an MBOX file to import. In the brief moment before crashing it creates an Import folder and an MBOX, but the MBOX is empty.
A few days ago, I got one MBOX to import. It shows up in the Library/Mail/V3/Mailboxes/ folder, and the MBOX container holds working messages. However, this MBOX doesn't show up in the side bar.
I went to a clone backup made shortly after installing El Capitan. I replaced Mail and every Mail-related file that was in my user Library. That resulted in instant crashes every time instead of intermittent crashes partway through an import.
I did a Safe Boot startup. The problem remained.
This is reason 49 on why it is bad to leave Snow Leopard. I wouldn't have switched to Mail except that Outlook 2011 can't search emails or run simple filters such as Unread. (Microsoft's recommendation is to buy Office 2016.)
Any ideas on how to fix Mail other than reinstalling El Capitan?
