I've had frayed insulation with multiple MacBook adapters and Lightning cables. I wonder if it is climate related; I live in a hotter and more humid place than Cupertino. In any case there is no excuse for the insulation being so fragile when $5 USB cables never have this problem.

Yes, me too, I'm sure the heat and humidity is a factor, but for the insulation to actually decompose in this way just from the climate is absolutely unacceptable.
