Bon !

  • le volume est monté > en lecture et écriture > un OS peut y être installé (ou restauré) = RAS
  • la distribution des dossiers-Système est complète > avec en plus un dossier macOS Install Data de qui recèle les paquets d'installation + un OS auxiliaire démarrable d'installation
  • le chemin de démarrage actuel pointe sur le démarreur boot.efi de cet OS d'installation auxiliaire > ce qui explique que ton Mac reboote toujours sur le programme d'installation bloqué.

Je vois très clairement ce qu'il faut faire. Mais avant cela --> une question :

  • est-ce qu'il s'agissait d'une mise-à-niveau d'un autre OS à High Sierra > ou bien d'une simple mise-à-jour d'une version de High Sierra à une autre ?
 
Du coup, j'ai suivi les instructions de #13 à #15.

Mon macbook air est récent (septembre dernier), et j'ai effectué toutes les mises à jour demandé au fur et à mesure. Cela doit être une mise-à-jour non ?

Voici le tableau issu de #13 à 15 :

J'ai fais une bêtise?
 
Belle initiative. Tout colle.

On va rajouter une petite couche de finition --> passe les 2 commandes :
Bloc de code:
kextcache -u /Volumes/"Macintosh HD"
diskutil ap updatePreboot disk1s1

  • la 1ère met à jour le cache de démarrage prelinkedkernel du volume Macintosh HD
  • la 2è met à jour les informations du volume de pré-démarrage Preboot

La 1ère passe sans commentaire. La 2è retourne un affichage conséquent --> poste-le ici.
 
ouf !

Tout est en place. Alors le test !

Va à : Menu  > Disque de démarrage --> choisis Macintosh HD et re-démarre -->

  • est-ce que l'OS charge et est-ce que tu peux ré-ouvrir ta session ?
 
Problème résolu.

Avec toi --> c'est vraiment : passez muscades ! - je n'ai pas l'impression que tu avais besoin de moi - si ?
 
Bien sur que si !
J'ai voulu suivre les aides que tu avais déjà donné, mais comme tout ce langage informatique m'est absolument inconnu je n'avais aucune confiance en ce que je faisais, et peur de faire pire.

Vraiment merci beaucoup ! Beaucoup ! Beaucoup !
(je vais pouvoir me remettre au travail maintenant)
 
Alors est-ce que tu as un DDE USB pour sauvegarder les données du volume avant reformatage ? - à moins que tu n'aies déjà une sauvegarde ?
 
Si tu as un DDE USB avec assez d'espace libre > via une commande du Terminal il est possible de cloner les 325 Go de données du volume Macintosh HD dans celui du DDE.

Sinon > c'est le reformatage direct.
 
Alors passe la commande :
Bloc de code:
diskutil eraseVolume jhfs+ "Macintosh HD" disk20

  • respecte les espaces ; mets bien "Macintosh HD" avec les ""
  • la commande reformate le volume terminal

=> poste une photo de l'affichage retourné par la commande.
 
La commande n'a pas trouvé le disque n°20 que j'avais indiqué d'après un tableau antérieur.

Est-ce que tu as re-démarré entre temps ?
