Preventing Big Sur via KACE

I know it's not publicly available yet, but I'd like to prevent as users from installing Big Sur. Is there something in scripting that anyone has tried in KACE 10. In a prefect world the user see the "install macOS updates" option as greyed out.

  • One way I've seen people do this online is making a dummy application in "Applications" with "Install Big Sur" and some odd permissions.

    But don't know the best way to implement this via KACE. - rwt 3 years ago

Not sure if this will help but I found the following link


In the post is tells you what command can be run to prevent an update running, as a guess you will insert Big Sur into the command, maybe

sudo /usr/sbin/softwareupdate --ignore "macOS Big Sur"

If you have the KACE agent installed with admin privileges you should be able to run that in a script

  • I haven't tested this, but this method supposedly was "obsoleted" by 10.15.5 so I'm not sure it would work. - rwt 3 years ago

Hope this info can help you out. I have 2 Online Shell Scripts that run on schedule. 

1.  Disable Automatic Updates. This will show the current status then turn it off 

echo Current status:

sudo softwareupdate --schedule

echo Ending status:

sudo softwareupdate --schedule off

2. Remove Mac OS Download Files - The second line will delete the "Install macOS (os name)" from the applications folder since they are usually saved to that location.

find / -name "Install macOS*"

rm -rf /Applications/Install\ macOS\ *.app
