MacOS High Sierra - Reinicios - MacMini

Buenas noches.

La pasada semana realice una instalación limpia de High Sierra en mi MacMini. Desde entonces realiza reinicios aleatorios, en los cuales, sólamente aparece la manzana con la barra de progreso estancada en la mitad.

Si dejamos en esta situación (sin forzar el apagado-botón) al cabo de un buen rato se apaga solo.

He realizado un diagnostico con la herramienta EtreCheck, facilitada por otra comunidad apple de USA, el cual indica el hardware de mi equipo y demás información.

La voy a publicar para ver si alguien pudiera darme una solución.

Gracias.
