Try lowering your Java security temporarily as I had the same issue (same Mac specs as well). See post 9 above. I started up my old windows laptop and had to install java on it, but I got the digital ID website to work for me and it's now created. Just out of curiosity, how do you lower the java settings for safari? I looked around and couldn't find anything that would allow me to do so. So now that I have my digital ID created can I use my mac to start the application process or do I need to stick with the windows laptop I created my ID with?
