Hello all I use my 2014 15” MB pro (has double video card, good processor and fast ssd) and after the stupid update yesterday (I use Catalina still and Safari updated too) my laptop won’t start. The fans blow off big time and screen is dark grey. It powered up a couple of times when off charger but when I plug it and the fans go off big time. Tried reseting Pram and Smc but now it won’t even start. I don’t know what to do. Is apple liable for this???
