Where apps hide your files
GarageBand's loops and instruments live in top-level Library folders shared by every account, while Logic Pro 12 packs its whole sound library into one file in your Music folder. Here is where each one is and how to reclaim the space.
GarageBand and older Logic Pro versions keep their sound content outside your home folder, in the top-level Library shared by every account on the Mac:
/Library/Application Support/GarageBand/
/Library/Application Support/Logic/
/Library/Audio/Apple Loops/
Logic Pro 12 (and MainStage 4) changed this. Apple's Logic Pro guide says it keeps all its sound files, including Apple Loops, patches, channel strip and plug-in settings and samples, in a single file in your Music folder:
~/Music/Logic Pro Library.bundle
Note the leading slash on the first three. That is /Library at the top of the startup disk, not ~/Library in your home folder. If GarageBand was installed but its extra sounds never downloaded, these folders can be nearly empty: on the Mac checked for this article, the GarageBand folder held only lesson content (ChordTrainer and Learn to Play, 17 MB in total) and the other two were empty.
Your own files sit elsewhere:
~/Music/GarageBand/
~/Music/Audio Music Apps/
~/Music/GarageBand is the default folder for GarageBand projects. ~/Music/Audio Music Apps holds your own patches and settings, in subfolders such as Patches, Plug-In Settings, Sampler Instruments and Databases.
In Finder choose Go > Go to Folder (⇧⌘G) and paste a path. In Terminal:
open "/Library/Application Support/GarageBand"
open "/Library/Audio/Apple Loops"
Finder shows Logic Pro Library.bundle as a single file. Logic's own Settings > General > Sound Library has a Show in Finder button for it. To see how much space everything takes, read only:
du -sh "/Library/Application Support/GarageBand" "/Library/Application Support/Logic" "/Library/Audio/Apple Loops" ~/Music/"Logic Pro Library.bundle"
du prints a "No such file" line for any folder you do not have, which is harmless.
| Location | Holds |
|---|---|
/Library/Audio/Apple Loops/ | Apple Loops for the Loop Browser (GarageBand, and Logic before version 12) |
/Library/Application Support/GarageBand/ | GarageBand content such as instruments and Learn to Play lessons |
/Library/Application Support/Logic/ | Logic Pro's instrument and sampler content before version 12; GarageBand uses some of the same content |
~/Music/Logic Pro Library.bundle | Logic Pro 12 and later: the whole sound library in one bundle |
~/Music/Audio Music Apps/ | Your saved patches, plug-in and channel strip settings, sampler instruments |
If you have both apps, they share content, so deleting a folder because "GarageBand is not installed any more" can break Logic, and the reverse.
Apple's GarageBand guide lists two commands, both in the GarageBand menu:
In Logic Pro 12, choose Logic Pro > Sound Library to open the Sound Library window, where each pack has a Get button. When a project opens with a message about missing sounds, it is asking you to download a pack, not telling you the project is damaged.
The full library runs to many gigabytes. Use the supported route first:
Deleting from Finder:
du command above.~/Music/GarageBand and presets in ~/Music/Audio Music Apps do not.rm. Finder may ask for an administrator password for the top-level /Library.This depends on the app:
Logic Pro Library.bundle from your Music folder to the new drive, then point Logic at it with Locate in Logic Pro > Settings > General > Sound Library. Apple says that once the copy is on the external drive you can delete the original to save space.You do not need to copy Apple's content. On the new Mac, download it again from the Sound Library menu, or carry Logic Pro Library.bundle across if that is quicker than downloading. Copy what is yours:
~/Music/GarageBand (projects)~/Music/Audio Music Apps (patches and presets)Spotlight treats Logic Pro Library.bundle as one file rather than looking inside, so a loop in it never turns up by name. Typing a loop's name, or part of one, into Everywhere lists the matching files in the top-level /Library folders, and, once Everywhere has Full Disk Access (macOS protects the Music folder), inside the bundle and your own ~/Music folders too. ⌘↵ reveals one in Finder so you can see which pack it came from. It matches file names only, not what the audio sounds like.
In /Library/Application Support/GarageBand, with Apple Loops in /Library/Audio/Apple Loops and shared content in /Library/Application Support/Logic. These are in the top-level Library, not the Library in your home folder.
Apple's Logic Pro guide says Logic Pro 12 keeps all its sound content in one file, ~/Music/Logic Pro Library.bundle. You can move it and point Logic at the new location in Settings > General > Sound Library.
Yes, if you can download them again: GarageBand > Sound Library > Download All Available Sounds or Reinstall Sound Library brings them back. Quit GarageBand and Logic first and move folders to the Trash rather than deleting permanently.
Apple documents no option for GarageBand. Logic Pro can: version 12 lets you move its library bundle, and earlier versions have Relocate Sound Library in the Sound Library menu.
Everywhere keeps track of every file on your Mac — including the folders Spotlight hides and drives you have unplugged. Free for a day, then $19 once.
