I have 3 Macs and I already installed Pod Updater 2005-06-26 with my 15" PB and iPod mini. However, my other PBs are also showing the same update on the software updater window and I am wondering if it is necessary to download the same update. I am guessing I don't need to do because that update was already synched up with iPod mini when I did originally with my 15" PB.
