Mavericks calendar doesn't update iphone 6 calendar
When I alter an event in Calendar on my laptop (10.9.5), the change doesn't show up in my calendar in my iphone (8.1.2).
Syncing is happening because changes made on my iphone show up on my laptop. New events on either show up in the other. There is just this one element that is missing.
What do I need to do to make changes to events in Mac Calendar show up in iphone Calendar?
iPhone 6, iOS 8.1.1, Macbook Pro 2012 OS 10.9.5
