    Folks, I want you to take a look at this and, for those who may know, tell me what it means. I was gently browsing the internet yesterday - a Brazilian news blog: - using Firefox on El Capitan Public Beta when, suddenly I got this:

    Display divided in two parts: Black and Yellow and
    Mac was completely frozen. I had to switch it off...
