Error downloading iphone/ipad app through iTunes
Hi all.
I'm running 10.11.1 on a macbook pro retina (late 2012) with iTunes 12.2.1.23. After upgrading to 10.11.1, every time I open iTunes a window pops open and prompts me for my iTunes store password. I haven't changed any settings and this has never happened before.
Additionally, I purchased Lumino City on my iPhone and when I sign into iTunes on my mac and it attempts to download the app, it fails and I get this pop up.
Any help with this would be appreciated. Thanks.
MacBook Pro (Retina, Mid 2012), OS X El Capitan (10.11.1)
