1332399 - “Thunderbird.app” is damaged and can’t be opened. You should move it to the Trash.

Status: RESOLVED INVALID

(Thunderbird :: Build Config, defect)

Earlier today I replaced my Thunderbird 45.6.0 installation (which I have since 45.3.0 installed) with Thunderbird 51.0 Beta. 

Then I started to experience permanent startup crashes (as reported as bug 1267288). After some unsuccesful restarts I wanted to downgrade again and downloaded 45.5.0 en-US from mozilla.org.

After moving the application to /Applications and trying to start Thunderbird, it gets refused by the following failure:

> “Thunderbird.app” is damaged and can’t be opened. You should move it to the Trash.

So I tried older versions from the 45.x.0 release and it still fails down to 45.0. 

But when I start the application from within the mounted DMG it works fine.

Markus, Wayne mentioned that you might know something about such a behavior?

Maybe this was a Gatekeeper internal bug which went away after restarting my machine. Most likely this was indeed related to the number of crashes and then the replacement of the application files due to the downgrade.

Happened to me too, on OS X El Capitan (10.11.6). Not sure exactly what I did to trigger (if anything), as I don't start Thunderbird every day on this computer.

Console only said:

I could start Thunderbird again after reboot.
