So apparently Apple has put out a new version of software for the 6th gen nano. Sweet, it has capabilities for me to manually tell the Nano to shut off. I tell it to go ahead and update. It gives me an error saying I do not have permissions and links me to a page that doesn't even list that error. I'm using a 2010 MBP 13" base model if that makes any difference (running Snow Leopard). I update itunes just in case it is that, still same error. Why won't it update and what can I do to fix that?
