I got a new MBP and it's from 2006. I wiped the hard drive clear with my install disk for Leopard. Then I updated everything, but I didn't have the apple apps. So I used the install discs that came with it (privately sold, by the way), and installed the 06 applications (ilife). This garageband has that 3.0 4 update. The thing is, my friend has this garageband that is 08 but has LESS software instruments. Mine has MORE How does this make sense..? I plan on using garageband a lot.
