iMac iMac 27 pouces late 2009 ne démarre pas : symbole d'interdiction

[pipobimbo62]

Bonjour,
Suite à une mise à jour Safari, mon iMac ne démarre plus et reste bloqué sur l'écran avec cercle barré.
Je fais suivre les commandes "diskutil list" et "diskutil ap list"
Merci de votre attention !

Bonjour, d'autres éléments à communiquer pour un diagnostic distant ? Pour ma part je n'ai rien trouvé. Peut-être sinon un problème de nappe SATA mais je ne me sens pas trop de le démonter.
Merci de votre aide
