I am on OS X Sierra on a Macbook Pro Retina 2015 and I have just experienced a strange, weird issue. My Macbook just randomly shut off, not a kernel panic, it literally turned off like the power was disconnected. I am at 42% battery and it started back up just fine.. I can't find any logs what caused it (probably didn't have time to write to log if it shut off suddenly). Anyone else has this?
