Ok so this weird thing happened to me: My Mac Mini 2012 power supply kinda exploded...
I needed the Mini on another station for the day so I unplugged it and (perhaps the mistake) took a random power cable.
Connected everything, power on. Switching to the keyboard... BOOM
The power cable...
I purchased my rMBP a Year ago and Yesterday after charging a few moments later I heard a Popping sound as if something had blown up. There was a faint smoke smell but i didn't suspect it to be the charger . When i plugged in the charger later on it was DEAD. There are no signs on the charger...
