There is a shared folder for Ableton Live Factory Packs, but each user will need to change their pack folder location to use it. This setting is per user per computer, so it will be easiest if students try to use the same computer for the semester. This will save users time downloading these huge packs, and it will save storage space on the Macs.
Please note that this will disable the ability to browse for packs. Any additional packs for the class will need to be requested from the IT Service Desk.
