The short answer
Usually, after a check. Might hold something you care about. Look inside before removing it.
What is it?
The shared Apple Loops collection used by GarageBand, Logic Pro and MainStage: thousands of short audio and MIDI loops sorted by genre and instrument. It typically takes a few GB, more when the full Logic Pro library is installed.
Loops shared by Logic Pro and GarageBand. Managed by the Sound Library Manager; downloadable again.
What happens if you delete it?
Apple’s loops can be downloaded again from Logic Pro’s Sound Library Manager or GarageBand › Sound Library. Projects that use a removed loop show it as missing until then.
How to remove it properly
Use Logic Pro › Sound Library › Open Sound Library Manager to remove loop packs. Deleting files in Finder needs an administrator password and leaves the loop browser’s index out of date.
From the app itself: Logic Pro > Sound Library > Open Sound Library Manager.
Before you delete it
Third-party loop packs you bought may also be installed here and may not be downloadable again: check before removing them.
How MoreRoom helps
