Hello, while doing audio work using a firewire Audio interface (Apogee Ensemble) audio stopped suddenly and i saw smoke coming out of my mac. I switched it off and opened it and found a burned chip. The computer still works (I haven’t dared using the firewire port) and wondering it it’s fixable maybe replacing the component. I don’t know what component it is and how it’s affecting the computer’s behaviour. You can see a picture here burned chip macbook pro mid2012 Picture Thanks! Guido
The part you damaged you is a 24volt fuse for the FireWire ports power service. You can see it here in this image: Logic board - Bottom side
