Tengo un iMac de finales de 2012 con 24GB o RAM y 3 discos USB conectados a él, todos corriendo time machine en secuencia.
Después de actualizar a catalina, cada vez que apago el sistema tarda mucho en apagarse y después de alcanzar el estado de apagado, a veces la pantalla se vuelve blanca de nuevo, como si fuera a arrancar de nuevo y después de un rato la pantalla se vuelve negra de nuevo con un mensaje de apagado en el medio, en varios idiomas.
Entonces, si inicio el sistema, veo este mensaje de bloqueo:
panic(cpu 1 caller 0xffffff7fa6c96aae): watchdog timeout: no checkins from watchdogd in 184 seconds (97 totalcheckins since monitoring last enabled), shutdown in progress

Me llama la atención esta línea @filesystems.msdosfs
... SISTEMA DE ARCHIVOS MS DOS???? ¡WTF!
Mis ideas eran reiniciar el SMC e intentar un arranque seguro. Ninguna de las dos cosas solucionó el problema, que persiste.
¿Qué pasos siguientes podrían ayudarme a evitar el choque?
