I have an update for iBooks Author waiting to be downloaded but when I try to enter my password to start the update I get this message in red under my user name "an unknown error occurred" and I have done the usual, restart, force quit. The username and password work fine everywhere else from my iPhone, iPad and in iTunes

    Make sure to quit the App Store before downloading updates.

     

    If that's not the issue, try deleting the cache, cookies, and preferences associated wtih the App Store.

     

    Quit the App Store if it's open.

     

    Now open the Finder. From the Finder menu bar click Go > Go to Folder

     

    Type or copy/paste:    ~/LIbrary/Caches/com.apple.appstore

     

    Click Go then move the Cache.db file from the com.apple.appstore folder to the Trash.

     

    Type or copy/paste:    ~/Library/Cookies

     

    Click Go then move the com.apple.appstore.plist file from the Cookies folder to the Trash.

     

    Type or copy/paste:    ~/Library/Preferences

     

    Click Go then move the com.apple.appstore.plist file from the Preferences folder to the Trash.

    You could try deleting the iBooks Author app then reinstalling. That should reinstall with the most recent version available.

    Try the App store menu item for logging into your account and look for the button to reset app store warnings. Click it and retry.

    I fixed mine by creating a new account with my existing information. It gives an error saying you already have an account and use that to login. Exited. Signed in and went fine.

     

    I think it's to do with the TOS acceptance, because I tried everything else and it didn't work.

    Thanks JoseffNYC, that worked for me. I just got to the point where the TOS and accepted that. I cancelled on the next screen and was able to log in normally. Easy!
