macOS 10.13.6 requires a software update to recognize iOS 12.1?
My mid-2014 13 inch MacBook Pro running macOS 10.13.6 displays a dialog reading "A software update is required to connect to [my iPhone]. Would you like to download and install this update now?" when I connect my iPhone 5S running iOS 12.1. Photos recognizes this iPhone, but iTunes does not.
What is required to use iTunes with my iPhone running iOS 12?
MacBook Pro (Retina, 13-inch, Mid 2014), macOS High Sierra (10.13.6)
