titleBlock Install macOS installers

To block users running macOS installers, e.g Install macOS add the following Launch Argument as per the steps below:

  • osinstallersetupd

For greater control over the application installers of macOS, with user interaction, take a look at the alternate method (designed just for this task) in the following KB:

macOS - Block Apple Install macOS Application

Step-by-step guide

Download, edit and associate the below Fileset. 



If you are wanting to block an Application with a space in the name like ,Keychain Access, you will need to have quotes(") around the name. So you would add, "Keychain Access", to Executable > Launch Arguments.

Blocking Install macOS Apps

Install macOS Apps may be blocked by supplying the following Launch Argument in the Fileset:

  • osinstallersetupd

However, this will block all Install macOS Apps.  If you wish to block one installer, e.g Catalina, but have workflows that require earlier versions to instal, consider the following Fileset example.

Inside the script you will find a 'case' block.  This section should be edited to meet your requirements.  Currently this example blocks Catalina only, but demonstrates how you could include other instal Apps or how you can capture all other installers.

Code Block
	case \$process_details in

			echo "Catalina"
			pkill -x "osinstallersetupd"
			echo "Found: Mojave"
			echo "Nothning to do"
			echo "Found: \$process_details"
			echo "Allowed.  Nothing to do"

Use this Fileset instead of the earlier one and supply all desired Apps to block as per the guide.
