ODBC driver for Oracle on Mac

[D4vidrim]

I use Livecode at work to connect to an Oracle db via odbc with my Windows pc and it works.
Sometimes I'd like to do it at home, where Ihave a Mac with Maverick: I have no idea how to setup the odic connections, because I cannot find any free oracle odic driver on google.
What I've found so far are the Actual ODBC Driver, which are not for free. Is there anything else?

Unfortunately Livecode requires me to buy the commercial edition if I want to use "direct" Oracle connection without odic...

Thanks
