I am using El Capitain on my Macbook Pro. iTunes will not sync future events from my iPhone 5S tcalendar to my computer. What am I doing wrong? I've tried syching again (multiple times), I have updated the iPhone to iOS 9.3.1. I don't know what lse to try.
MacBook Pro (Retina, 13-inch, Early 2013), OS X El Capitan (10.11.4), iPhone 5S
