Actually, their “solution” to that problem was to just replace the logic board with another logic board with the same issue. They just postponed the inevitable death of the machine (caused by a design defect) until after their extended repair program ended.
My 2011 machine was repaired under that program, and died again about a year later from the exact same gpu issue. The Apple Store even diagnosed it.
The Apple Store refused to fix it the second time, stating that they would break California state law if they fixed it and instead only offered to sell me a new machine at full price. I got the machine up and running again by disabling the dedicated gpu, and when I pointed this out to Apple’s customer relations team they gave me a free set of Bose QC35 ii headphones as compensation.
I’d rather have seen that they had actually solved the engineering problem, but that costs more than dodging customers and giving away headphones.
