I have always had trouble getting NUD to iCal. The Now Software utility never worked reliably before, and refuses to work under Leopard. So I resorted to manually transferring key items over.
Then last month I found a fantastic utility called iCalSyncNUTD. It comes from some company whose website East Coast Silicon
discussed the product. Let me tell, this product works! It worked 100% in transferring all my NUD dates over, and the cost is only $3.
I don't know anything about the company and what other programs they do, but this one gets 5 stars. It is reliable, never crashes, works, and is unbelievably priced.
In many years, Now Software has never been able to do this with their calendar and then these guys come along and do it for $3. What a deal!
I recommend this product. Very Happy
