Query: DOES NOT WORK ON A MAC!!

This product has not worked on a mac for the past 18-24 months and perhaps never since OS 10.3! DO NOT PURCHASE THIS IF YOU INTEND TO USE IT ON A MAC. The company does not support anyone's complaints and directs them to Apple for a solution.The product is still marketed for cross platform use and the company knows it does not work - do not support this company!
