My Ipod 3rd Gen will not add music any more from my macbook. I tried updating my ipod and it says it's updated. this is what I keep getting. This version of the iPod software (4.2.1) is the current version. It will not up date. I have all my music in my itunes program on my mac and I can not sync the music. My Itunes software is. This version of iTunes (11.1.5) is the current version.
