I have a mid 2012 A1398, after having it “repaired” by Apple two years ago the problems with the dgpu are back, as far as I have read it’s probably not the chip itself but a small component. There’s a famous repair shop that repair the machines in NY, but they suggest of finding a repair shop locally. Are you aware of any that does it? Thanks for your help!
See if these folks can help you RS-Tech Informatica find a local person
