I wonder how to make a 2010 Macbook Pro with High Sierra (10.13.6) restart when power adapter is plugged in. "Energy Saver" panel shows no "Start up automatically after a power failure". sudo pmset -a acwake 1 doesn’t work. I tried a NVRAM reset. sudo nvram AutoBoot=%03 doesn’t work. pmset -g capshows that autorestartis not an option. I use the MBP as a music streamer (iTunes, Bit Perfect, "Remote" App on the iPhone, optical output). Battery is disconnected. I want the MBP to turn on if power is switched on by the amp - without touching the MBP. Anyone any Idea? -Martin

  • @Buscar웃 it runs on the power adapter. That's why he wants the MacBook to automatically perform a reboot, like iMacs do (if enabled) when disconnected from power. I suppose MacBooks don't have that option by default as they are expected not to suffer from sudden power loss because they usually have batteries in place..

  • @Buscar웃 Kevin Grabher Yeah. The amp is on the cabinet, the MBP is placed in the drawer. The MBP power adapter is connected to the amp. When I turn on the amp, the power connector is connected to power and the MBP should turn on (Itunes is auto started). When the amp is turned off - well, there’s no battery, and the MBP suffers from sudden power loss ...

  • I don't know the solution to your problem but I just might want to add that it is generally not a good way to power off a computer by just "plugging it out" instead of a proper shutdown. You might experience file/system corruption at some point.

  • I think you have to do that in the boot sector.

Try doing that in the boot sector.

Use Restore > Disk Utility > Terminal

  • Thanks for your answer. I forgot to mention: pmset autorestart 1 is no option on my system - I checked with pmset -g cap. Sorry!

  • I tried sudo pmset -a acwake 1 - it’s in the list showed using pmset -g capbut didn’t work. I also tried a NVRAM reset.
