Just upgraded to 10.14.2 and my iMac won't stay up for more than a few minutes. I've seen some chatter around about crashing on sleep, but I've disabled sleep and the crashes still happen. I've only seen the crash once myself (it's usually at the FV login screen when I come back to it).

There are many /Library/Logs/DiagnosticReports/*.shutdownStall files. I ran spindump -i on them, but didn't see anything useful.

Here is the output of log show --predicate 'eventMessage contains "Previous shutdown cause"'

Googling around, it looks like -128 shutdown code is unknown (maybe memory). I'm mainly posting this before I go to all the trouble of assuming it's bad memory or something and not a bug in Mojave.

  • It looks like the crash happens when the Screen Saver activates. – Chris W. Dec 26 '18 at 18:44
  • I have a Macbook Pro 15" retina Mid '15 and I am experiencing a very similar problem. Like you it started to happen with the 10.14.2 update. I never had this problem before. – Pierre Thibault Dec 29 '18 at 18:20

This problem was addressed by upgrading the OS. I'm at 10.14.5 now and no longer have these problems.
