I'm on 10.4.1 and I just synced fine. Wow, iSync over Bluetooth is awesome, I'm glad I upgraded to Tiger...no more USB cable for me.

Sorry, I don't know how to help you--I really didn't have to do anything. It just worked!!


However, I couldn't sync my iCal calendars. iSync kept telling me it needed to open iCal and it does, but then iSync itself never refreshes to allow me to select which calendars to synchronize. I'm sure this is a little bug that will be fixed soon enough.
