iMac se despierta sin ninguna razón aparente

Tengo un iMac de 27" a fines de 2012, OS X 10.8.4 y anoche se despertó del modo de suspensión mientras estaba a 3 metros de él. Nadie más que yo estaba en la habitación. La pantalla de inicio de sesión estaba visible. Después de algunos Segundos, la pantalla principal volvió a ponerse negra, pero la pantalla del segundo monitor (de LG, conectado a través de un adaptador Thunderbolt) siguió brillando con una luz gris oscura. Así que presioné una tecla en el teclado, la Mac se despertó de nuevo y Lo envié a dormir presionando el botón de encendido. Ahora ambas pantallas estaban negras y me fui a la cama.

Lo busqué en Google hoy y encontré el comando pmset -g logque imprime un registro de hibernación, y en este registro encontré evidencia de eventos de activación aún más extraños. Esta es una parte de este registro:

El espeluznante evento de despertar que estaba viendo fue en 2013-08-10 22:50:51 Pero el archivo de registro muestra aún más actividades mientras dormía en mi cama:

2013-08-11 00:01:35
2013-08-11 02:52:04
2013-08-11 04:07:32

El próximo despertar fue iniciado por mí: 2013-08-11 04:07:32
¿Pero cuáles son las razones de esos eventos en medio de la noche? ¿Por qué mi iMac se despertó?

Verifique sus mensajes de registro escribiendo lo siguiente en la Terminal mientras busca la marca de tiempo de cuándo ocurrió.

syslog |grep -i "Wake reason"

que le dará un informe completo solo por motivos de alerta.

ACTUALIZAR:

Mirando su registro ahora, todo parece normal.

Tenga en cuenta que el único momento en que su computadora puede hacer algo de limpieza es durante el tiempo de suspensión. Eso está previsto por diseño.

Sin embargo, para evitar despertares no deseados , deshabilite la activación para el acceso a la red wifi.
