I upgraded to macOS High sierra and now my system shuts down automatically at night. This is quite annoying.

I tried looking in System Preferences > Energy Saver > Schedule… settings but, there's no schedule set.

Can someone please help me with this.

I am using MacBook Pro 15" Mid 2015

  • The only place I know that could be set to do that is.. System Prefs > Energy Saver > Schedule There was recently a question where someone found that was enabled without their knowledge. – Tetsujin Sep 29 '17 at 06:24
  • Thanks @Tetsujin, I have already checked it, it is not enabled. – banjara Sep 29 '17 at 06:48

    Same problem here on a Touchbar MBP 15". Hoping a dot release fixes it. – simontarr Oct 04 '17 at 01:38
  • couple of days back, I reinstalled "command line tools" and after that I haven't faced this issue, I don't know how they are related. – banjara Oct 05 '17 at 05:07
  • @banjara: How did you install this? Me too facing this problem ! – Akshay Lokur Oct 08 '17 at 11:06
  • @AkshayLokur you can download it from App Store. – banjara Oct 08 '17 at 18:04
  • @banjara Thanks for reply. I searched but App store does not return any results for "command line tools", do I need to search something else? – Akshay Lokur Oct 09 '17 at 02:33

    @AkshayLokur try 'xcode-select --install' – banjara Oct 09 '17 at 04:53
  • I checked the Schedule settings (which were off) and already have command line tools installed. Problem still persists on two machines. Most nights whilst in sleep mode, they do a shutdown. Occasionally they stay in sleep mode. – drekka Oct 18 '17 at 11:33
  • Could you add in your question if these "shutdown" happened on battery or power supply? – dan May 14 '18 at 17:00
  • @drekka: do you still have these unsollicited shutdowns? Do they happen on battery or on power supply? – dan May 14 '18 at 17:02
  • Nope, all been good for a while. – drekka May 16 '18 at 01:28

Installing "command line tools" solved this issue. However, I have no clue how they are related.

To install command line tools run following command in terminal.

xcode-select --install

I have had the same issue each day since installing High Sierra. However, in my case, the computer doesn't shut down, but rather goes into deep sleep. I called AppleCare and they acknowledged the issue and said they are working on it.
