Apple Event: May 7th at 7 am PT
I have a late 2013 Mac book pro with retina display and after upgrading to El Capitan it just randomly shuts down. I can find no rhyme or reason for when it decides to shut down. It even shuts down when I'm not using it and is closed (I can hear it chime) Any help? I had to start up again just now because it shut down while I was typing this.
MacBook Pro with Retina display, OS X El Capitan (10.11.1)
There have been several abnormal shutdowns in the last few days. A negative shutdown code may indicate a hardware problem. The precise meaning of the codes is not publicly documented.
If you haven't already done so, you can try resetting the System Management Controller. Otherwise, or if the reset has no effect, see below.
Make a "Genius" appointment at an Apple Store, or go to another authorized service provider. You may have to leave the machine there for several days.
Back up all data on the internal drive(s) before you hand over your computer to anyone. There are ways to back up a computer that isn't fully functional—ask if you need guidance.
If privacy is a concern, erase the data partition(s) with the option to write zeros* (do this only if you have at least two complete, independent backups, and you know how to restore to an empty drive from any of them.) Don’t erase the recovery partition, if present.
Keeping your confidential data secure during hardware repair
Apple also recommends that you deauthorize a device in the iTunes Store before having it serviced.
*An SSD doesn't need to be zeroed.
