Q: 12" MacBook Crashes and reboots every night in sleep mode

Overnight, every night, my 12" MacBook reboots after crashing While in sleep mode. Occasionally, I hear it reboot. But, without failure, when I lift the lid of the Mac I will have a crash report message and opportunity to report it to Apple.

 

The only other oddity with this Mac is that it forgets it has a Facetime camera. I'll have to reopen the app three or four times before it recognizes the problem.

 

does anyone have have an idea?

MacBook, OS X El Capitan (10.11.6)

    There are Console logs and crash reports that itemize details in the system

    which may be helpful in the course of actual troubleshooting. To log a KP

    or kernel panic (if you get a restart message, etc indicating such occurred.)

    Given the instructions above, you may be able to get a report from MacBook

    and then enter it into a reply in your thread here in ASC. Also, if you have an

    easily repeatable issue, and an Apple Store with Genius isn't too far off, you

    may choose to see if an appointment with Genius may help reveal this matter.

     

     

    Have you tried a system management controller - reset, as outlined here?

    Because your model MacBook computer does not have a user-removable battery; note:

     

    If the battery is non-removable

    1. Shut down the Mac.
    2. Plug in the MagSafe or USB-C power adapter to a power source and to your Mac.
    3. Using the built-in keyboard, press Shift-Control-Option on the left side of the keyboard, then press the power button at the same time.
    4. Release all keys, then press the power button again to turn on your Mac

     

     

    Not sure what among the NVRAM information stored in the MacBook would affect

    the issue yours has; you could read & perhaps reset it - info here: NVRAM or PRAM

     

    In any event...

    Good luck & happy computing!
