I am on iTunes 12.5.1.21 on OS X El Capitan 10.11.3. I would like to know where (by default) downloads are written (I am downloading many iTunes U lectures in sequence).
Window > Activity shows me active downloads which I can pause and cancel, but that isn't exactly what I need. I can also click the tiny arrow at the top right of the iTunes navbar that shows up when you are downloading something, but it just gives me the same tools as Window > Activity.
