I bought this last week and finally popped it into my iMac today. In order to view the videos it said my browser needed the Real Player plugin. The plugin that was included did not work with Safari or Chrome or Firefox. The only browser this software is compatible with is Internet Explorer. To my disgust I downloaded IE for Mac on to my machine, but even still, the Real Player plugin was undetected. I'm sure if I were more proficient with outdated products like Real Player and IE, I could dig into the advanced preferences and make it work, but I'm not. I'm a Mac user, and I prefer technology that actually works.
