How do I import address book
I want to import my lengthy address book from my my old iMac (PPC 10.4.11) to my sparkly new iMac (Lion 10.7.2 3.1GHz. 8GB RAM). I backed up the existing book to an .abbu file and transferred it to the new desk top from my "passport". I can't make the new address book accept the .abbu information. Someone please tell me that I dont't have to do this laboriously "card" by "card".
iMac, Mac OS X (10.7.2)
