A good scantool native to Mac OSX??

I'm looking for a good scantool native to mac OSX. I want to be able to read and clear trouble codes, and look at some data with my macbook. Has anyone had any experience with Movi?? www.yhasi.com seems to be the only one I can find. It is a good price, and looks like it has everything I would need. I'm just wondering if anyone has used this software, and if it works well.

Just a hobbyest looking for a cool tool:-)
