I used to use sudo pmset -a hibernatemode 25 to try setting my MacBook to hibernate instead of sleep, so that it pulls power away from the RAM/hard drives, etc. and puts the laptop into a proper sleep. A few major updates ago (maybe El Capitan), pmset ... 25 no longer worked to set my MacBook into hibernate/safe sleep. I'm using a MacBook 13" from 2017. Is hibernate no longer supported on this model? After hearing about the defect in the 15-inch MacBooks from 2017, I have to admit that I'm concerned they'll find an issue with 13-inch MacBooks as well, and I want to be as safe as possible. I use a lot of applications whose state needs to be maintained across many days for development and testing, so shutting down my computer every day is not efficient nor is it a viable option. Here is my pmset -g custom after running sudo pmset -a hibernatemode 25 to try enabling hibernate mode again:
