The loopdown utility has been created to make it easier to download and deploy the audio content that accompanies GarageBand, Logic Pro X, and MainStage 3.

Each of these apps has a 'mandatory' set of packages that the user is prompted to download and install when the app is first run, followed by a prompt to download the remaining optional packages and install them.

In both cases, the user must provided credentials for an account that can install software, which is not always possible in managed Mac environments.

From time to time, Apple changes the set of packages that these apps require. For environments where pre-deployment of this content is required, it can be a challenge to keep updating the content in a repeatable manner.

loopdown aims to make this process easier to manage.
