Can I delete the GarageBand and Logic sound library on my Mac?

/Library/Application Support/GarageBand
/Library/Application Support/Logic
/Library/Audio/Apple Loops

By Parsa Nasirimehr

Yes, if you don't use GarageBand or Logic Pro: the apps download their sounds again when they need them. If you do make music, Logic Pro can move its library to an external drive instead.

How big it gets

On the Mac we measured, one Mac on macOS 27: 2.4 GB: GarageBand 1.0, Logic 0.9 and Apple Loops 0.5. A full sound library downloaded in the apps takes many times more.

What it is

What writes itGarageBand and Logic Pro, when they download their sound library: instruments, loops and drum kits.
SharedThe three folders are shared by both apps.
AdministratorThey are in /Library, so moving them to the Trash asks for an administrator password.
Comes back?Yes. The apps offer to download the sounds again.

How to clear it

  1. Quit GarageBand and Logic Pro.
  2. In Finder, choose Go › Go to Folder for each of the three folders and move it to the Trash, entering your password when asked.
  3. If you never use GarageBand, delete it from Applications too; it's free in the App Store.
  4. To keep the sounds on another drive instead, use Logic Pro › Sound Library › Relocate Sound Library.

What you lose: The sounds, until the apps download them again.
