Self Service for GarageBand Loops

Self Service for GarageBand Loops

2018, Jul 18    

With the move to Volume Purchasing for Apple Applications through MDM, I was left wondering how we could add the GarageBand loops to our systems if users wanted to use GarageBand. Before I would run the wonderful project appleLoops and then package them to install when installing GarageBand with Munki. Well since GarageBand is now automatic that method would prompt the user afterwards to install the GarageBand loops and what we definitely saw with new systems was seeing the loops available when the application finally pushed down with the new MDM approach.

To rememdy this I got to thinking couldn’t we just pull the appleLoops python script down to the system and then run it on demand now that Munki supports on Demand scripts? The answer is yes, and this way you are always pulling down the latest version of the script and getting the latest version of the loops so there is no need to run this periodically and import into your repo. To acoomplish this, I threw together a very simple bash script that will download the GitHub project and then extract and run the script through a Munki on demand nopkg script. This way users that actually want to use GarageBand can download the loops at their convienience. Here is the package info that you can copy and change to your repo’s liking.
