I finally upgraded to 10.12.1, and use NMI quite often. I can confirm that
Cmd+Option+Shift+Ctrl+Escape no longer works.
But the suspend; perl -i -pe 's/(?<=pendingNMI\x00{4})\x00/\x01/' *.vmss;
resume: trick still works for NMI.
But at the moment, there still is no KDK for 10.12.1 16B2555 so I can't
attach lldb to it anyway.
