Hello, Somewhat comforting to know this isn't only happening to me, as unfortunate as it is for all of us who are having to deal with it. I have the same problem, tried rebooting while holding down the option key, now I am trying with "T" but as yet nothing has helped. Maybe a class action suit against Apple? This would be the third one that I know of. If anyone finds a solution that is simpler and works, I would love to hear about it. Good luck.,
I have a MBP Late 2012 Model and the same thing has started happening to me too!

I have done all the Remove Mem and PRAM and reset, remove Batt, Cmd and R etc etc......Really Frustrating as I have just purchased Adobe CC for the Mac and have been using this for my photography!!! More money down the drain. Apple are the worst in looking after their customers. "Apple throwaway society".......Maybe a Class action suit would be a good idea...!
As an IT Engineer, coming from PC world, where there was constant trouble with Software, Hardware, Virus, all the drivers who were overwritten by new programs or doesn't fit and the system did get unstable after half a year. All the reformatting and reinstall I did know in the PC world, did stop when I did buy my first Mac in 2009. One first install, then automatic update and never ever one second I did experience any trouble.
So much time I did spent in the PC world since the early 1980s, without any Class action agains Microsoft or HP or Dell or IBM. They still have not solved the most simple problems like finding a printer / scanner or phone and is often a huge source of frustration amongst our students - whilst with Mac non of the problems occur at all.
But now on my MacBook Pro from 2009 pink flickering stripes showed up on the white surfaces in all Apps. Not on the white startup screen, not on an external screen. It is ok when this Macbook Pro is cold, but after starting up, the problems occurs slightly. So it must be something to do with the expansion of metal when the laptop is getting warm... Did only look for a quick solution here - but only get frustration and blaming.
Starting a class action against Apple, after 10 years of perfect operation is perhaps a bit stingy and making very high demands, compared to all the other computers and stuff we buy.
