Casio Clavinova ap80r, Mac OS connection?

[dlj]

I had a my casio for a few years now and have been using a mac for a lot longer. Not long after I got it I tried connecting it by USB, but it didn't work and casio did not provide the drivers for Mac, just windows. but now I want to connect it up for use in programs like garage band, logic pro and "piano hero". Is there any way of connecting the two so that the piano registers fully with these and other programs? Thanks for any replies
