I have a Late 2013 rMBP running uptodate OSX and iTunes.
One thing I've always noticed is whenever I see in iTunes that apps need updating and I click update, it then asks me to enter my password even when those apps are free (not really an issue but a slight annoyance) it will update the first app and I have to then click update again (this time I don't enter my password) and it updates all the subsequent apps. Why do I have to update twice? It's been like this ever since I got my Mac (using an iPhone 5S).
