Ok, so for my birthday my mom got me the new iPod nano. She didn't know that I could not use it because our iMac has os x 10.4.11 and it requires os x 10.5.8 or later. I haven't been able to use my birthday present for almost a year now and I don't know what to do. I've looked at many reviews and such from customers trying to get help, but I just don't understand what I need to buy. I don't want to waste my money by getting the wrong thing. My processor is a 2 GHz Intel Core 2 Duo. I have 1 GB 667 MHz DDR2 SDRAM memory. My iTunes version is 9.2. and I really need some help so I don't get the wrong thing and so I can actually use my iPod.
