For me it says
kernel: (AppleSMC) Previous shutdown cause: -20
The attached PDF (and the internet) doesn’t seem to have any information about this code. What’s the source of the codes for the PDF? Maybe they have updated listing for shutdown codes.
we also have -20 as a cause and have no idea what it means. did you ever find it out?
