Merci pour votre réponse.
J'ai effectué les manipulations préconisées. Pendant quelques jours ça a marché. Mais tout à coup, couper une âtre fois. Le ventilo est à fond aussi sans faire tourner aucun programme.
Je note qu'entre temps j'ai installé le MacOs High Sierra sur un SSD.
Je joint le résultat de message log après le redémarrage :
