"MacBook Pro suddenly dead and does not turn on"에 답변I have the same problems TODAY. No response from Mac Pro 13 “ Retina Early 2015 after holding down the power button. I try the SMC reset . Plug out the AC power. HOLD THE KEYS: SHIIFT, CONTROL, OPTION, AND POWER SIMULTANEOUSLY FOR 10 SECS. THEN Release. Hold down Power button for 15secs. It power up again. IT works !
