MacBook Pro Ecran de démarrage bloqué

[Poehere]

Bonjour,

Depuis hier matin, mon Macbook Pro reste bloqué avec la Pomme et la barre de chargement qui se charge tout doucement et reste bloqué à 100%.
Le mode sans échec ne marche pas ni même la réinitialisation de la NVRAM et de la SMC.
J'ai aussi fait l'utilitaire de disques avec le SOS mais cela n'a rien changé.
J'ai voulu réinstaller MacOS via le même utilitaire mais la barre de chargement est resté bloqué encore à 100%.
Quand je le lance en mode utilisateur détaille cela me dis que le process 286 et les suivants ont "crashes open directoryd et qu'il y a "too many corpses being created".
J'ai également tape dans le terminal "diskutil list, diskutil cs list " et d'autres commandes et j'ai obtenu cela :

-bash-3.2# diskutil list

Merci d'avance d'avoir pris le temps de me répondre et j'espère que j'aurais des solutions car je ne sais plus quoi faire.

La réinstallation de High Sierra ne se termine pas elle s'arrête à 17mn et l'ordi se met à redémarrer et bloquer de nouveau en fait donc je sais même pas si ça pourrait résoudre le problème.
