Answer to "Auto power on, when connect my MagSafe."Hey guys, I’m having the same issue and I came across this - https://apple.stackexchange.com/question...-does-a-mac-laptop-startup-automatically-after-a-power-failure - Unfortunately *I* can’t test it because I wiped out OS X and put Linux on it without having a way to restore OS X. But you guys (if you’re still checking this) can give it a shot and let me know if it works! Update (11/06/2018): Got a spare USB drive with an OS X installer on it today! Installed OS X, ran the terminal command, and problem solved! Confirmed working!
