Hi, Can you elaborate on what was happening to your machine regarding 'which was spontaneous black screen and poweroffs'? My late-2013 Macbook Pro has recently started similar behavior. Somewhat randomly the screen will go black, sit like that for a while, then fans speed up for maybe 10 seconds then it eventually turns off. This whole cycle is something like 20 seconds. Is this similar to what you observed which was fixed in your case by the script?

YES! This is exactly what I was experiencing. Well, to be exact, there were three or four different failure modes. What you described is one of them. Another was sometimes I close the lid to put it to sleep, and instead the fans would rev to 100% and sit there forever until I held the power button. I have the script running in a terminal window and haven't had a spontaneous poweroff for 2 weeks now.
