MacBook Pro crash after sleeping for a long time I have a MacBook Pro (15-inch, Late 2016) running macOS Sierra 10.12.1 (16B2659). Recently I found out that if I left my machine sleeping for a long amount of time (about 15+ hours), it will cause a kernel panic and restart itself so when I open my computer the next time it will tell me the computer have shutdown unexpectedly. Is this a software bug or my computer have problem?

EDIT:

I got this problem today. The shutdown cause is -128. Maybe a hardware failure? Also sometimes instead of a crash, I also have this problem. (I posted that as a separate question since it's not a crash). Here is the crash report.
Occasional kernel panics are more nanannoyance than something to be fixed. 


How serious are occasional kernel panics?


However, if you can make them happen, there is a process to resolve them:
