So I just got my new 17 inch macbook pro. I open up garageband only to see that not all the loops are there. so i click on it and it opens up saoftware update saying it will download the rest of the grayed in loops that aren't downloaded yet. well i've tried a few times and to no luck. it says all software is up to date and is done. how do i get it to download the rest of these loops?
