Make sure That you have, in your bitcoin.conf file located in ~/Library/Application Support/Bitcoin at least the following:
server=1

Restart Bitcoin client, enjoy Bitcoin solo mining. ;)

Ensure that you must have a locally-running instance of Bitcoin-Qt or `bitcoind` running with its JSON-RPC interface active.
