Nunca tuve un solo pánico de kernel en el iMac de retina de 21 "(finales de 2015) desde que lo obtuve a principios de este año.
Esta mañana, cuando comencé a usarlo (por lo general no está apagado, ya que hay tareas que debe realizar durante la noche) había dos actualizaciones listas para instalar: 1password e iTunes. Una vez realizada la instalación (no tengo idea si están conectados de alguna manera), el iMac inició el kernel en pánico con bastante regularidad sin dar una idea de una posible causa.
Este es el último informe:

Comencé a eliminar 1password y deshabilité el ayudante de itunes. No ayudo He desactivado todo tipo de cosas de inicio: nada. He creado un nuevo usuario: boom. Revisé el disco con la utilidad de disco: no se encontraron errores. Comencé el programa de prueba de hardware y no detecté problemas.
Comenzó a sentirse mal una vez que se bloqueó en modo seguro y, más tarde, se ejecutó en una memoria USB recién creada (en otra Mac, al igual que en la actual) se estrelló con El Capitan 10.11.5.
Desconecté todos los tipos de dispositivos, quité el monitor externo, saqué el cable LAN, incluso cambié el cable de alimentación: aún no funciona.
¿Qué hacer ahora?
