I've been trying to sync my address book and iCal via .mac by iSync. I've followed the instruction to register my 2 macs under my .mac account. After registration is done, i start to sync with .mac one by one. My newly purchased powerbook synced without any porblems because basically it has got nothing in it. But, when i sync my old iBook, it said "Monday, 17 November 2003 4:17
Can't synchronize contacts to Steven Chang: device is not available
Can't synchronize calendars and To Do items to Steven Chang: device is not available" in an alert dialogue.
What really is going on here??
Also, what is the alternate way to sync two macs beside using .mac account?
