What is a NoPkg?

A NoPkg is a Munki PkgInfo item that can be deployed with Munki without being associated with a specific PKG or DMG.

A NoPkg typically uses an installcheck_script or an installs array to determine if something is installed. If something is not installed, it will run a postinstall_script. Every time Munki runs, a NoPkg will check for changes in the “installed” state and will run the script if needed.

NoPkgs are great for running scripts and automatically checking for changes in the installed state. They can also provide self-service scripts via the Managed Software Center.

See the official Munki documentation for NoPkgs:

How to create a NoPkg

To use a NoPkg with SimpleMDM, you’ll first need to create one. As noted in the official Munki documentation, there are typically three components to you’ll need to include:

  • installcheck_script: to determine the installation status
  • postinstall_script: the script you want to run
  • uninstall_script: a script to uninstall the original script (optional)

Once each of those components exists, the NoPkg can be created by running the following command on a Mac with Munki tools installed:

makepkginfo --nopkg --name=NAMEOFYOURNOPKG \
  --pkgvers=1.0 --installcheck_script=/PATH/TO/installcheck_script \
  --postinstall_script=/PATH/TO/postinstall_script \
  --uninstall_script=/PATH/TO/uninstall_script \
  --unattended_install > NAMEOFYOURNOPKG.pkginfo
