HD/Library/Audio/Apple Loops/Apple/Apple Loops for GarageBand. Contains 1198 aif files about 1 gig HD/Library/Application Support/GarageBand/Apple Loops/Apple Loops for GarageBand. Contains 1106 aif files another one gig. Most of the files appear to be the same. I've just done an archive and install. Where exactly should the loops reside? I've just checked this on another computer and it is the same. Two questions: One, which set of loops does garageband use and Two, why are they duplicated? What is the reasoning behind this.
