Does this work with current version of OS X key-chains? If yes, this
will be the most promising option for developing a JtR plug-in.

It looks like this tool too uses OS X internal calls (people have
complained about its speed).

I also found a new tool : osx-keychain-brute
(http://mirror.transact.net.au/pub/sourceforge/p/project/po/potaru-pentest/,
no sources though). Looks like it calls SecKeychainUnlock function.
Claimed speed is 500 k/s.
