Cómo encontrar quién estaba usando remotamente mi mac ... Aquí están los archivos de registro

Así que me alejé de mi mac durante unos 30 minutos y cuando regresé, alguien abrió una nueva pestaña de Facebook y estaba cargando una imagen. Tan pronto como estaba detrás de la computadora, se detuvieron. No podría haber sido alguien aquí en la oficina mientras observaba mientras se cargaba la imagen. ¿Cómo puedo demostrar que sucedió y cómo puedo averiguar quién fue?

Los archivos de registro largos están en el enlace de abajo. Noté que esto sucedió exactamente a las 14:00 y maté la red por un minuto o dos. También en los registros a continuación, donde hay un espacio, eliminé estas líneas para reducir la cantidad de líneas de registro:

com.apple.xpc.launchd [1] (com.dtv.vgconnect [22021]): El servicio se cerró con un código anormal: 127 com.apple.xpc.launchd [1] (com.dtv.vgconnect): el servicio solo se ejecutó durante 0 segundos. Empujando el respawn hacia fuera por 10 segundos.

Muchas gracias por tu ayuda. Aquí está el archivo system.log durante aproximadamente 3 horas alrededor del incidente:
