Calendars and Contacts not syncing between iPhone and Mac
Hello.
I am using a MacPro4,1 (early 2009) running OS X 10.9.1, and an iPhone 4 running iOS 7.0.4.
In iPhone, Settings > Mail, Contacts, Calendars, Calendars Settings are set to: Sync – All Events.
In iTunes, Sync with this iPhone over Wi-Fi is checked.
Calendar and Contacts aren't syncing, in neither direction, neither over Wi-Fi nor by cable. (I haven't, and won't try iCloud or however that thing is called now.)
No idea why. I'd be thankful for any hint.
iPhone 4, iOS 7
