To be clear, this was not an app crash, but more of a catastrophic upgrade failure.
1. I am running 1password 7.9 and the autoupdater starts.
2. I enter the credentials for it to complete.
3. During the process 1password stops(expected), but it never restarts.(unexpected)
the autoupdater says that 1password upgrade failed.(try again?)
4. I look and see a 1password.app that is 10MB and is not starting.
5. I try to reinstall, but it fails again.
6. I see no way to download a new dmg from 1password.com without signing up for an account.
7. give up on the process and restore from backup
This is a great exercise in recovering from a 1password failure.
Of course, I can access my data from the website. (what is my secret phrase again? where is that? hmmm...)
I could have walked over to my phone to get the data there too.
But it stopped working everywhere including the extensions on the browser because they couldn't hand shake any more.
Took a good 30 minutes to fix.
My guess is that when the autoupdater was running, it either couldn't talk to the server or it downloaded a corrupt file.
I don't know if either one of those are valid otherwise loads of people would be complaining now. -_/-
Ill try to recreate the problem, but I'm not sure about your diagnostic tool helping because 1password wasn't running at the time.
