Automotive diagnostic programs?

Hey, first off, want to say I'm a newbie here, but it looks like you guys know what you're talking about, so I must be in good company. But here's my question:

Is there any free programs out there that I can download that will allow me to read the diagnostics of my car's OBDII port? There are tons of programs for Windows (granted, there are ways to make it work), but I'd like to find a program that is made for Mac. Any ideas?

What are they? My laptop is a Vista machine, so that would be more practical. Thanks.

I know that the best for windows is RomRaider. It's made with Subarus in mind, though it will work for others. It's only available for Windows Vista and Linnux.
