New GarageBand Jam Pack Loops after Mountain Lion Upgrade
I went to an Apple store recently, and I noticed that GarageBand had jam pack loops I don't currently have, even with the most updated version. I recently upgraded to Mountain Lion 10.8.3. How do I get the latest jam pack loops? I tried to get a new GarageBand app, and I get a message I am up to date.
iMac, OS X Mountain Lion (10.8.3)
