Since I upgraded my Mac to Lion and IOS devices to 5.0.1 I can sync recurring calendar entries to iPad and iPhone from the Mac using advanced settings on iTunes (Replacing calendars with info only from my mac) However, when I do a regular sync I get an error message on my Mac "Syncing with xxx iPad will change more than 25% of your calendars, events or to dos on this computer. The before has the correct info. The after has a start and end for the next day. If I don't stop the sync I get an event listed twice on two separate days. I have spoken with the tech department several times and all of my time zones are correct and I've got iCloud turned off (what a mess). Has anyone else had a problem like this and discovered a fix? Could it just be a New Zealand problem? Please advise.
