There is trouble in paradise. My 2011 iMac has a faulty graphics card and has all the classic symptoms. After taking it for a checkup with an Apple tech, they confirmed my own diagnoses. After doing some research I found there was an recall on my iMac, but I was unware of it at the time in 2013 when they issued it. Now I am stuck with a computer that is going to cost more than it’s worth to fix. So I guess it’s time to recycle it and start saving for a new one.
