Bonjour,

Je travaille sur un Imac 27", Intel Core I5, 8Go de RAM et 1 To de DD.
Le problème, c'est qu'il a tendance à s'éteindre complètement sans raison. Parfois, c'est quand je redimensionne une photo sur Photoshop, parfois c'est une navigation sur Safari. J'ai regardé dans les logs du Mac mais j'avoue ne pas tout comprendre non plus.
Est-ce que cela peut-être un pb/virus dû à un logiciel/application ou plutôt un pb matériel ?
Je l'éteins tous les soirs. J'ai vérifié la température du poste mais elle ne me semble pas alarmante.
J'ai un peu peur que ce soit grave !

Merci de votre aide.
 
Pardon, de ne pas avoir répondu plus tôt mais c'est "seulement" aujourd'hui, après 2 minutes d'allumage que mon Imac s'est éteint. je vous ai donc fait une copie de ce que j'ai pu trouver dans la console et il s'est éteint vers 9h. S'il manque des bouts de message, dites le moi, je re-ferais un copier-coller. Merci de votre aide
