Tengo un MacBook Air, a principios de 2015, ejecutando macOS Mojave. Durante las últimas 2 semanas, se ha estado apagando y reiniciando inesperadamente en períodos de tiempo variados.
Al revisar los registros de cierre, encontré que el código de cierre era -128 ; Al revisar varias fuentes en Internet, descubrí que este era un código de "captura de todos los problemas de hardware". Muchas fuentes demostraron que esto podría deberse al sobrecalentamiento de la computadora o al funcionamiento incorrecto de la RAM o la batería.
Mi computadora no se sobrecalienta cuando se apaga / reinicia; La batería parece estar funcionando bien y no he instalado ninguna memoria RAM de terceros. La información del sistema parece mostrar que ambas tarjetas RAM están en estado "OK".
He intentado hacer lo siguiente
- Restablecimiento del SMC.
- Restablecimiento de la NVRAM.
- Arrancando en modo seguro.
en vano.
El problema comenzó repentinamente cuando estaba ejecutando macOS High Sierra (lo estaba ejecutando durante bastante tiempo y el sistema operativo estaba estable). Acabo de instalar MacOS Mojave (borrando todos los datos anteriores), así que estoy bastante seguro de que no fue causado por algún tipo de malware. Apple no muestra ningún mensaje como "Su computadora se apagó debido a un problema", y los registros no muestran ningún error del Kernel.
He ejecutado diagnósticos de hardware, pero no ha mostrado ningún problema. También he ejecutado First Aid bajo la Utilidad de Disco solo para estar seguro.
Otra cosa que he notado, que no estoy seguro de que haya estado allí antes, es que durante el arranque, con la barra de carga a la mitad, la pantalla de la computadora repentinamente se vuelve negra por uno o dos segundos, y luego Vuelve para continuar desde donde lo dejó. No estoy seguro de si esto está relacionado.
Para ser claros, el período de tiempo entre reinicios y paradas es muy variado; una vez, se reinició tres veces durante el uso en un minuto o dos. Por lo general, solo se apaga en modo de suspensión (no causado por autopoweroff ; sigue siendo el mismo código de apagado), después de horas sin uso.
Me he dado cuenta de que el registro de apagado es exactamente el momento en que lo inicio. Realmente no sé qué hacer con él.
Aquí hay algunos registros del segundo antes de que se apague el equipo con el código -128 (y también el momento en que intenté sacarlo del modo de suspensión):

¿Hay algo más que pueda probar antes de entregar el MacBook a un profesional? Lo he estado usando desde hace aproximadamente dos años, y no está cubierto por la garantía.
