Have an iMac that had to be factory reset. Made a complete backup with Time Machine prior so have all original system and data on external drive. Reset the mac to OS X.8.5 after wiping the drive using Disk Utility/Apple Restore and it worked perfectly. Then after restore, used Migration Assistant to restore all user data that was backed up. Opened iTunes and all content is present, including playlists, play counts, etc. Have reauthorized the mac in iTunes. However, of over 400+ AudioBooks, I am not able to play the content because the "mac is not authorized", meaning that a different Apple ID, Audio.com, or other account credentials were used when the content was purchased. Using iTunes Get Info, I can clearly see what Apple ID was used to purchase the content and is the AOL screenname from years ago. Problem is today AOL screennames are no longer validated through the iTunes store and I am unable to reauthorize the mac to play any of those purchases.
I have access to AOL account so I know the credentials.
I have access to Audible.com account so I know the credentials. When I log into audible, I see only 30+ purchases so I know the library did not all come from Audible directly even though each of the books begins with 'This audio book is presented by Audible.com, audio that...' so I know they are Audible content.
If I was to use Migration Assistant and choose to migrate all apps, all settings, all users, etc., instead of just concentrated folder selection as I did, this would not be an issue so that tells me that somewhere, there is a file that ties to this mac and contains all the credentials needed to play DRM content previously purchased with the AOL screenname credentials.
I need to find that file and restore it.
I do not want to revert the mac back to before reset as that is counterproductive and defeats the entire reasoning for resetting to begin with.
Even Apple is not able to help because they claim the authorization process has changed so greatly that they have no way to regrant the purchases for 400+ audiobooks where not all of them came from the iTunes store, and obviously only 30+ came from purchases directly with Audible.com.
Audible.com did provide assistance to get the 30+ reauthorized and playing without problem. That leaves over 370+ audio books that will not play.
Can anybody point me in the right direction to restore the entire iTunes data without reverting to going back to the old drive image?
