I have two iPods, 80 gb Classic and 16 gb Nano (touch with FM radio). I plug them into my 2012 Mac Mini and I get this message: iTunes has detected an iPod that appears to be corrupted. You may need to restore this iPod before it can be used with iTunes. You may also try disconnecting and reconnecting the iPod. I plug them into my MacBook Pro or MacBook Air and they are fine. I've tried both a USB port on the back of the Mini and the USB hub in my HP display with the same result. Any idea how to resolve this?
