macOs Sierra "previous shutdown cause: -2"?

Hi everyone,


I have recently updated my mid-2012 MBA 13" to Sierra (10.12.6). I did a clean install. Since then, my MBA shuts down randomly. From the log I get "previous shutdown cause: -2"; what does this correspond to? It is getting very annoying! I am starting to feel nostalgic about OS Tiger with which I never had any issue...


Best,

Berthii

MacBook Air, macOS Sierra (10.12.6)

Tiger was released to the public on April 29, 2005 hard to believe anyone would feel that nostalgic. 😉

The only thing I can pull up is:

vTypErr = -2, /*invalid queue element*/

and I am unsure how to interpret this cause and effect. Documentation is scant. Carbon Core Enumerations—
