Hi, Not sure this is the right forum, but would appreciate some help. I have an iphone 4s and an iMac. I currently sync my google calendar to my iphone via exchange and to my iMac via CalDAV. I sync my google contacts to my iphone via iTunes and to my iMac via the sync tool inbuilt in Address Book (I do this because I like to reorganize the contacts into the correct groups in Address Book before it syncs to my iPhone). The problem I'm having is that while the calendar syncs fine between google and my iphone, it doesn't sync well between google and my iMac. If I delete/modify entries in google calendar, some of the changes/deletions get reflected in iMac, but some don't. Am I missing something here? Is there a better way to do all this?
