Kernel panic aléatoire sur iMac

Bonjour à tous,

Depuis quelque temps, je suis confrontée à un problème que je n'arrive pas à résoudre !

Mon iMac crash de manière aléatoire, quelquefois juste après le démarrage et l'entrée dans ma session et plus souvent après quelques minutes, voire quelques heures d'utilisation sans qu'il me soit possible de déterminer une cause reproductible du problème. C'est ce qui rend la recherche de la panne plus compliquée.

C'est aussi pour ça que j'aurais besoin de vos lumières, car là, je sèche grave !! :-((

Si une âme charitable pouvait se pencher sur le rapport de crash ci-après et m'aiguiller, cela m'arrangerait beaucoup.

Début rapport :
