The new update will not take to my husband macbook. When I open iTunes, and check for updates it tells me there is a new update, but when I go to software update it tells me that everything up to date. I also have tried to download it from the Apple website, it runs normal, but nothing happens, iTunes 8 is still on his Macbook. He has the Late 2008 13 UBM 2.4Ghz. He had no problem updating his iphone to 3.1. Thanks in advance.
