That would make sense to me if anyone ever had access to my machine. I bought it from Apple directly, it is a refurbished machine it has only solid state storage, which I strongly suspect was cleared out before they shipped it to me. This is not a really important question obviously but I was just curious how they wound up on my machine. Were they part of a demonstration package Ford garage band, are they the audio track something else that I download (I find that very suspect). My guess is that it will forever remain one of the mysteries of the universe. Thanks for taking the time to reply.
