Random shutdowns using MacOS SierraMy late 2013 MacBook Pro 15" Retina MacBook Pro the screen flickers slightly, then 5 seconds later, the computer shuts down. ...
Responder a:MBP turns off Randomly Without WarningAfter getting to the point where my MacBook Pro won't stay powered on for more than a few minutes at a time, I finally broke down and went to the Apple Store. After 6 months of progressively worse and random shutdowns, thousands of dollars in lost time and revenue, and abject, utter frustration . The Genius Bar "guru" ran a bunch of tests, and of course, my computer passed all with flying colors. They told me to leave it and they'd open it up to diagnose further. Finally they told me that one of the screws that holds the heat sink in place has snapped and I need to replace the motherboard! A brand new motherboard when the computer is less than 3 years old and in mint condition? I was floored. I paid almost 2k for this computer, and now have to pay another $600 to fix an obviously faulty part?! I'm beyond livid at Apple and it's BS.
