For recording the BEST is “Logic Pro” software. And the training for it is called “Lynda”. It’s a video training, so you do not need to BE anywhere to get it, and it IS the training video all Mac Employees use. Hands down it is simple, monkey see and monkey learn to do very quickly.
I do recordings too, for Rock Bands.
I Logic Pro is way way overkill, then the cheaper answer is iLife which comes with most Mac bundles or you get it separately pretty cheap, and includes a very stripped down version of Logic and other editing software. And when I say stripped down I mean for Apple Standards... what comes with it is usually far BETTER than the most radical custom expensive recording software you could Buy just 4 or 5 years ago anywhere.
CALL APPLE and talk to them, they actually WILL answer questions. Just call the nearest apple store even if it is 300 miles away.
