Importing the latest MacOS upgrade into Munki

Follow the following instructions to import the latest macOS upgrade to munki for distribution to all Orchard Macs.

Downloading the latest macOS release

To download the latest macOS release we use a python script by Greg Neagle. This script can create disk images containing macOS Installer applications available via Apple's softwareupdate catalogs. The script is already located in a cloned github repo located on the build host Autumn-Glory /srv/munki/macadmin-scripts please ensure the repo is up to date prior to running.

Run the script installinstallmacos.py as the root user, chose a macOS and download.

importing into munki

Once you have your dmg downloaded, use munkiimport to manually add the dmg. The name should always relate to the macOS for example Install_macOS_Big_Sur and ensure the version is correctly applied, Installer_item_location is macOS.

Create and set icon

Find the product page icon icns from within the dmg, you may have to mount the original dmg and search. Create a 256x256 png file of the icon, named the same as the munki pkginfo's Name key to /srv/munki/orchard_repo/icons

Scoping

Use manana.orchard.private to create a new computer attribute mapping. Insert an attribute value of a pre-configured Jamf Smart Group all the computers you want to scope to.
