Truck diagnostic code scanner OBD II for Apple?

[webexplorer]

I am looking for a diagnostic code scanner OBD II to verify my light truck system. Do you know some list of names of the brands?

I found one that might be compatible with Apple computer: http://www.mactools.com/productdetails/tabid/119/c-23109-scan-tools.aspx

EDIT: Maybe, it is not worth it. I just searched other type of scanners that do not require a computer. Perhaps, that would be better.

Thanks.
