Updating album artwork on ipod
i Tunes Authorization basically tells Apple that the apps, music, and media you have purchased belong to you, and that you have the rights to them and thus that media can be copied and synced to your i OS devices.
All you need to do is switch the USB cable from one port to another and see if it works.
It will not work if they are not joined to the same network.
If USB syncing isn’t working but Wi-Fi syncing is working, then you may have a faulty USB cable, or there may be an issue with the USB port you are attempting to use, and that leads us to the next troubleshooting tip.
i Tunes is a digital media player, written by Apple Computer, for playing and organizing digital music and video files.
Additionally, the program connects to the i Tunes Music Store which allows users to purchase digital music files that can be played by i Tunes.
Once the i OS device has been restarted, try syncing again. Try using Wi-Fi syncing instead to see if that works.
