quickpkg VS Installomator

Composer works, but I'm a fan of quickpkg. Builds a deployable package from a .app, which is exactly what you're looking to do.

If you have access to a Mac, Installomator is a good encapsulation of shell scripting.

I used to use something like the above script but switched to using Installomator for all apps we use that it supports. It can do the initial install as a push or from Self Service, and then you can set it up to patch software as well. https://github.com/Installomator/Installomator

If you want to make things easy for your users and yourself, take a look at Installomator. It'll unlock a lot of nice workflows for your users, since you could put a specific title's install action available in Self Service and thats always gonna be easier than trying to track down the vendor's URL and finding the right download. It also means you don't have to repackage anything.

Munki is not an MDM and I recently learned there's this project called Installomator that might help.

Looks like you’re trying to update/work with version 4 but the installomator version is still on version 3. I’d suggest using build a label for musescore4
