Acabo de actualizar a la versión 10.14.2 y mi iMac no se levantará por más de unos minutos. He visto algunas conversaciones sobre el bloqueo del sueño, pero he desactivado el sueño y los accidentes siguen ocurriendo. Yo solo he visto el bloqueo una vez (generalmente aparece en la pantalla de inicio de sesión de FV cuando vuelvo).
Hay muchos archivos /Library/Logs/DiagnosticReports/*.shutdownStall . Corrí spindump -i en ellos, pero no vi nada útil.
Aquí está la salida de log show --predicate 'eventMessage contains "Previous shutdown cause"'

Al buscar en Google, parece que el código de apagado de -128 es unknown (quizás memoria). Principalmente publico esto antes de tomarme la molestia de asumir que es mala memoria o algo así y no un error en Mojave.
