Now that I am all ready with my fresh OSX 10.10 installed, I have noticed that the screen starts flickering and then freezes. Sometimes I can go back an work on my computer after the flickering stops, but most of the time the whole computer crashes and restarts itself. I googled and apparently it was a fw problem with the display. I downloaded the fw, but it is not available for my version. Do you think that it that it's going to be hardware related? I hope Apple releases another fw update if they already haven't.
