HELP!  I have updated everything I am suppose to and I can download blackra1n, but when I try to click on it, it will not open it says there is no application to open it.  What am I doing wrong?  I have a mac, and I need some very basic or detailed instructions on what I am doing wrong.  I really just want my intelliscreen back!
