I have noticed a quite strange pattern with my software updates: Over the past several months iTunes keeps reminding me that there is a newer version of iTunes available and when I click the button to update it, App Store loads, but under Updates section I find nothing to update. I have also noticed it with other system updates when I read there is a new security or other updates of the system, but my App Store can't find anything. I saw on the forum that there is a Security Update available today, but again, my App Store can't find anything. Is this a bug or is there something wrong with my App Store or iTunes? Is there a way to fix it? To complete the picture: I am using mid 2012 MBP with i5 processor with 4GB RAM, ML. iTunes version: 11.0.2 (26), App Store version: 11.2.2. I am using the Italian version of iTunes/App Store.
