Fire up the Console app in Utilities and filter the system log for "shutdown".

Sometimes it gives a shutdown code or some other details that can indicate whats going on.
Modern MacBooks wake up and do stuff in their sleep quite often. Time Machine backups being just one example. I think you can switch that behaviour off in the energy saver system preference.
I have plenty of more important things to do, if only I could bring myself to do them....

That indicates it didn't just power off for any reason. Even a dead battery writes a shutdown code into the log I think.

Typically you get a line like this:
Previous shutdown cause: 3
It only shows under the system log though, not under 'all messages'.

Could be its logging out rather than shutting down.

So your apps don't reopen when you log back in? Thats weird. It should do that whether its a logout or a restart.

Not all of us like apps and windows to reopen. I disable that at shutdown every time using the checkbox.

However, after a forced shutdown, the system ignores the checkbox and always makes apps/windows reopen. I haven't lived in HS enough to notice if the behavior is identical, but under Sierra if apps/windows don't reopen, it definitely didn't crash.

No, that is for crashing applications. Look under System IIRC.
The new Mac Pro has up to 30 MB of cache inside the processor itself. That's more than the HD in my first Mac. Somehow I'm still running out of space.

IIRC =If I remember correctly. I don’t have my Mac with me this weekend, will check the exact location when I get home.

The system log is useful. If you go past midnight, the system log breaks and starts anew. But you can still view the old ones up to a week ago.

Click on /var/log - not the disclosure triangle. Instead, click to highlight /var/log itself. This will reveal the full list, not just the subfolders. That's where the system.log actually lives, along with the zipped up previous days. Which you can view just by clicking on - Console reads the .gz without issue.

system.log.0.gz is yesterday
system.log.1.gz is the day before, etc.

I've lost track of where the panic log appears. Apple kept moving it around.

Please also check the powermanagement folder under var.log.

Ah, now you've got it:

The machine has a Sleep Timer that will automatically put the computer into hibernation (a sort of "deep sleep") after three hours of sleep, to conserve battery. That's the "Darkwake" at 13:55.

This function is the reason for the MacBooks' tremendous standby times, and nothing to be concerned about.
