The digital signature on the update is missing or invalid.

After today's update on Monterey, I get a notification that I have pro format update available... But when I try to click on it, I get an error that the digital signature is missing or invalid... I get this same error on 2 different machine, any way of getting an update with a valid digital signature?


MacBook Pro and an older trash can Mac Pro.. Same error on same update.

Similar here on M1 MBP. I'm at 12.6 and tried to install 12.6.1 and ProVideo Formats from "other updates available," not wanting to put 13 on just yet. The update downloaded and I think I waited a bit or started to go ahead but got sidetracked by having to quit apps. Rebooted and now getting the error.


PS. I had updated M1 MBA yesterday to 12.6.1 and then this morning to 13 with no issues. The MBA is not mission critical so went ahead and updated. Want to wait on MBP for at least several days.


Guess a feedback needs to be filed. But not surprising a glitch with so many updates going out.


OT: PSS. Where is the M2 Mini?
