I tried downloading the Garageband sound library which is 16GB, before it was even 5GB into the download it had added 40GB to my “system data” and I can’t get rid of it, I’ve deleted Garageband and the sound library and stuff and I can't get it to go away. Does anyone know a way I can get rid of it without having to format my computer? This is a brand new computer I just got this week and just finished setting up
