This update seems to by-passed our delay configuration and gave user 5 minutes to prepare a reboot.
Is anyone seeing the same issue?

And in the news you're going to love category, after installing Catalina 10.15.5, or the 2020-003 Security Update for Mojave or High Sierra, the softwareupdate tool will no longer recognize the --ignore flag to hide "major new releases of macOS". We knew it was coming for 10.15.5, but adding it to the Security Update for High Sierra and Mojave is a rude middle-finger to Mac Admins from Apple.

^ YES

This leaves Mojave with no way to block Catalina from showing up in the software update system preferences pane.

Mojave 2020-003, Catalina ignored in softwareupdate, updates deferred 90 days in MDM, Catalina still available in Software Update pane. See you all on 10.15.5 I guess.

Updated the article to include download links for the 10.15.5 combo, delta and both 2020-003 security updates.

No configuration profiles can be added to block the installer? Or simply blocking the macOs Catalina installer.app?

Does adding Install macOS Catalina.app to disallowed list still work?

I know APPL want everyone on latest and greatest the moment it's released but organizations need to have this control.
Basic support, manpower, user training, software compatibility... I don't have to preach here.

@atomczynski > Does adding Install macOS Catalina.app to disallowed list still work?

Yes, blacklisting app works, but action happens after user download full installations image, opens app. And it doesn't not prevent System Update messages "Update is available, install it". Expect more support calls...

Just to double check 15.5 update is not respecting "forceDelayedSoftwareUpdates key"? That is what I am seeing I just started testing it a few days ago...

What is a good way to deploy this to everyone? We've done our testing and it is working for us. The built in prompt for software updates/user apple software update servers isn't the greatest.

I'm looking for some sort of script that would download combo and update.

@j_allenbrand What about softwareupdate -i -a

I've tested the softwareupdate -i -a -R, and it did work for my system going from 10.15.4->10.15.5.

@mhasman Thats works but it doesn't really work from going from 10.14.6 to 10.15.x. Its good for the incremental ones.

Hi jamfNation,

I am getting error in few macs like this:
To install these updates, your computer must shut down. Your computer will automatically start up to finish installation. Installation will not complete successfully if you choose to restart your computer instead of shutting down. Please call halt(8) or select Shut Down from the Apple menu. To automate the shutdown process with softwareupdate(8), use --restart.

Any idea about this?

@Rohitds14 I have tried to use the Execute Command option in a policy, but am getting errors on a few. Any success?

Running command softwareupdate -i -a --restart...

Error installing updates.

Have same **bleep** issue, and I don`t know why. Yesterday works flawless, and security updates from today show me this.... I am getting tired

The shutdown thing shows up if there is a firmware update that it needs to install. If you use the -R switch, it should handle that gracefully.

Has anyone noticed a change in behaviour relating to recovery keys? I'm starting to see users who's recovery keys were generated "today" all over. It seems to replace the existing entry with the same key, like the same key's just been re-sent.

With the test I did, the key was "re-sent" on boot. No inventory scan or anything, just on boot from a deep(?) sleep. I imagine it would be the same whether the MBP had been off.
