Get more sounds and loops for GarageBand on Mac
After you install GarageBand on your computer, additional content—including patches, drummers, and Apple Loops—may be available.
Some additional content may be needed to perform certain tasks. In these instances, a dialog appears, informing you that additional content is needed, and asking if you want to download it.
In case the Sound Library is altered or stops working, you can reinstall the patches, loops, and other content in the Sound Library to its correct location.
Some additional content can also be downloaded directly in the Library and the Loop Browser.
