Updated: Fix for iTunes AppStore Update Errors (page is outdated & error 5002)
I’ve discovered the iTunes iOS App update error (The information on this page is outdated.) can be caused by never quitting iTunes.
The new fix: Try quitting iTunes every once in a while. I’ve found I still get this error if I leave iTunes open and sleep my MacBook Pro overnight. Simply relaunching iTunes when you first wake your Mac might fix this error.
