I started installing IOS 7 with iTunes yesterday evening before going to bed, and when I tested on it this morning iTunes download window showed it was completed. I just examined for it in ~/Library/iTunes/iPhone Software Updates and it's not there. Did Apple switch where the download goes to?
If I keep in mind correctly, to up-date several iPhones/iPods I would need to link each device individually then Choice click the Update button in iTunes and then navigate to where the up-date downloaded to. Is this right?
