Just got a MacBook Pro, the calender appointments do not transfer to my iPhone 5 calendar I just got a MacBook Pro laptop and am in early stages of learning.  The calendar that comes with the computer does not transfer the appointments to my iPhone 5S. I could never get Microsoft Outlook calendar to transfer either. What do I need to do to get the transfer to occur?
On both devices make sure that under iCloud settings Calendars is on. This will ensure that both calendars are syncing with iCloud simultaneously.
