I have to do a project with Dr Java but it doesn't work on my macbook pro 2012. The website allows me to download Dr,Java on my laptop and the icon even shows up on the desktop, but when I click it to open it it says "this file is damaged, move to trash?" I tried downloading it from firefox (used safari originally) but the result was the same. Some one please help this is very urgent, i need to complete my project by next monday!!!!!!!!!
