iTunes evolves over time, and sometimes there are good reasons why features don’t seem to work as they should. In this week’s column, I discuss why apps don’t transfer from iOS devices, and how to get them back. Yet some changes are inexplicable, such as one affecting an iTunes Store menu; I explain a workaround for this change. Finally, I look at a problem with duplicating playlists, and offer a possible fix.
Q: All my apps have disappeared from my iTunes library. iTunes also refuses to let me transfer the apps from my iPhone or iPad. The Transfer Purchases menu command is visible when I right-click on my iPhone, but nothing really happens. How can I get them back?
