My macbook somehow erased all of my address book. What do I do?

Time machine would be a good place to look (if you use it).
Any backup of the full system would do.

I can’t imagine what could have randomly deleted the contacts, though… were they moved? Use spotlight to search for names, and other things you would find in the contacts: such as unique phone numbers.

They’re just gone. I have tiger so I don’t use time machine. I searched for contacts and found nothing. I also opened ichat and it was as if I was turning on my computer for the first time- it was in setup mode or whatever.
I only backup documents. Would it be anywhere in my docs folder, do you think?

The folder you need to look in is:
~/library/application support/addressbook

This is were all of your Address Book contacts are stored. (just looked it up).

If not there, then I think you are out of luck.

Hopefully, you have a backup of the personal library somewhere…

Is this only your adressbook or other things on your mac aswell?

Well my ichat is wiped too, but that is tied to my address book so it’s definitely related.

Also, under app support there isnt even an address book folder.

I can’t even imagine how that could happen accidentally. Everything else on your machine is normal? Do you use MobileMe (previously .Mac)?

I would restore it with MobileMe or TimeMachine, provided you use either of these.

I am in the same predicament – No folder under the application support or anything~ I belive myself to be a fairly good Mac person – and would never delete such files – So I am as puzzled as can be….Can a new folder be recreated? Or use one from another computer?
Any Help would be greatly appreciated!
