There are no updates available for any of the apps in your iTunes library
For the past few days when I try to update the apps via itunes on my mac, I get the message "There are no updates available for any of the apps in your iTunes library". Now I know that this isn't true as I get updates on my iphone, ipad and my husband's iphone. I have tried logging into both mine and my husband's account on itunes on mac and still no joy. The only workaround I have found at the moment, is to manually type in the name of the app that needs updating in the search facility on itunes store and then the update box appears for that particular app. Not only is this time consuming and frankly a pain, but it relies on me remembering the names of apps that need updating. This has only happened in the last few days and was working fine about a week ago. I haven't changed any settings on the mac (running OSX Lion).
I can't seem to find any solution. The only post that I have found is possibly some Apple server issue, but that doesn't explain why updates still work on iphone and ipad. Help please (am now really fed up with this).
Unfortunately Apple phone support has been most unhelpful...
