Actividad inexplicada de la networking sobre el process APSCourier y apsd

macOS Sierra. 10.12.3.

Sin embargo, viendo la utilidad CONSOLE veo actividad de networking constante para un error "APSCourier". El process con el nombre "apsd" también se muestra en Activity Monitor con un pequeño porcentaje de uso.

¿Hay alguna manera de resolver cualquier problema que tenga el sistema para que este process cese? com.apple.idmsauthagent es para qué exactamente? com.apple.icloud-container.com.apple.cloudpaird quizás tiene algo que ver con iCloud, tratando de conectarse a los files de synchronization? Pero, no estoy usando iCloud a propósito.
