The first time I ran Syncmate 2.6 to put my Address Book on a new Macbook, a bunch of conracts marked "no name" popped up on the source computer (iMac). I was not sufficiently alarmed. I then ran a couple more sysncs, making a change on each computer to check the syncing went both ways, after which I noticed, again on the iMac, that I had a whole bunch of new contacts, each with no name and with several email addresses. I finally put two and two together and realized that all these addresses were from entries that had ONLY an email address. I stopped using Syncmate at that point, before it could completely mangle my entire address book. Luckily had a recent backup.
Can you give me any hope that Syncmate can be made to work? I really like the parts that work correctly.
