I'd like to move GarageBand's lessons ("Learn to Play") to another drive. How do I tell GarageBand where to look to find the files?
Some context : I removed my Late 2009 MacBook's SuperDrive and now have two internal drives, a SSD drive on which I boot and the original internal drive. The "Learn to Play" directory in /Library/Application Support/GarageBand is now 7GB and I haven't downloaded all the lessons I want. It is on the SSD drive, but I need to save space on that disk. I think that for the lessons it is less important to have a fast drive than for the loops and instruments (but maybe I'm wrong?), so I'd like to move them to the other drive.
