El iMac se despierta sin ningún motivo apreciable

Tengo un iMac 27" de finales de 2012, OS X 10.8.4 y anoche se despertó del modo de suspensión mientras yo estaba a 3 metros de él. No había nadie más que yo en la habitación. La pantalla de inicio de sesión era visible. Después de unos segundos, la pantalla principal se puso negra de nuevo, pero la pantalla del segundo monitor (de LG, conectado a través de un adaptador de rayo) seguía brillando con una luz gris oscura. Entonces pulsé una tecla del teclado, el mac se despertó de nuevo, y lo mandé a dormir pulsando el botón de encendido. Ahora ambas pantallas estaban en negro y me fui a la cama.

Hoy he buscado en Google y he encontrado el comando pmset -g log que imprime un registro de hibernación, y en este registro encontré evidencia de eventos de despertar aún más extraños. Esta es una parte de este registro:

Sleep/Wakes since boot:31   Dark Wake Count in this sleep cycle:1

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 siguiente despertar lo inicié yo: 2013-08-11 04:07:32
Pero, ¿cuáles son las razones de esos acontecimientos en medio de la noche? ¿Por qué se ha despertado mi iMac?
