I am on BigSur 11.6, I have been lately observing this issue where the installer command is hung while installing package. When observed carefully I see that the last thing executed by the installer is trying to verify the package. Here are the logs, I feel there is a bug either in trustd or installerd where in corner case it waits on a lock forever. Any suggestions to over come this issue? 2021-11-17 18:16:58+01 OSX3-BigSur installer[14815]: Set authorization level to root for session 2021-11-17 18:16:58+01 OSX3-BigSur installer[14815]: Administrator authorization granted.
