I have an early 2011 17" MBP and I'm a Blender user. I just became aware of Radeongate two or three months ago and have been hoping ever since that I would be lucky and wouldn't be affected.. Just now, however, as I was working in Blender, my screen started tearing and flickering. I immediately saved my file and quit Blender, which automatically made the graphics card switch back to integrated only, and the screen went back to normal. Opening Blender or otherwise activating the discrete AMD Radeon HD 6750M graphics card now makes my screen go black. What do I do? Should I refrain from powering down? I have seen some threads about Radeongate-affected MBPs not even booting up.. I depend on Blender for my livelihood, and as far as I have read, Apple has still not announced any type of replacement program or compensation. Is this accurate? I bought the full 3 year apple care protection plan, which I hardly used and of course just expired in February of this year. I am so pissed right now, I don't know what to do.. I sold my car for this computer, and now it's practically worthless to me.
