Hallo, I have iMac (OS 10.8.5 Mountain Lion) with iTunes 11.1.3 and I am trying to sync Calendar with iPhone 5 (iOS 7.0.4) but sync doesn't work anymore. I tried also with other device (iPad mini) but same result: no sync anymore. It wordked fine until 3/4 days ago.
I tried many solutions but no solved the problem:
- delete/restore calendars of iMac Calendar
- select the Sync Calendar checkbox and tried to select one calendar at a time to see if it syncs
More, in iTunes the Sync Mail checkbox is disable and it is no possible to activate it: in the past I could select mail accounts I wanted to sync, now there are no mail accounts in the box and the checkbox is disable (but it seems mails sync correctly... so don't understand why...).
I tried with a MacBook air with the same version of iTunes and it works perfeclty.
I think the problem is in iTunes: have I to reinstall iTunes? How? How do that without loss library, apps etc?
