Bonjour macomaniac,
J'ai également le même problème, suite à une mise à jour de MacOS High Sierra.

Voici le résultat de la commande "diskutil list"

Bloc de code:

En espérant que vous pouvez m'aider. Merci d'avance.
 
Salut John

Je ne peux que te proposer de passer les 3 commandes que j'ai communiquées à nadj juste avant toi (j'ai ajusté bien sûr le nom du volume qui diffère) -->

- donc passe les 3 commandes (l'une après l'autre) :
Bloc de code: 
diskutil info /Volumes/"Macintosh HD"
ls /Volumes/"Macintosh HD"
bless --info /Volumes/"Macintosh HD"

  • respecte tous les espaces ; mets "Macintosh HD" entre "" ; le "l" de "ls" est la minuscule de "L"
  • la 1ère retourne un tableau d'information sur le volume
  • la 2è liste ses dossiers de premier niveau
  • la 3è affiche la chemin de démarrage inscrit sur son en-tête

Poste ces tableaux qui permettront un diagnostic du type de plantage de la mise-à-jour dans ton cas.

Re,

J'obtiens ceci :

Bloc de code: 
-bash-3.2# diskutil info /Volumes/"Macintosh HD"
Could not find disk: /Volumes/Macintosh HD
-bash-3.2# ls /Volumes/"Macintosh HD"
ls: /Volumes/Macintosh HD: No such file or directory
-bash-3.2# bless --info /Volumes/"Macintosh HD"
No mount point for /Volumes/Macintosh HD
Can't get mount point for /Volumes/Macintosh HD
-bash-3.2#

J'ai dû faire une erreur ?
 
@ nadj

Alors c'est que FileVault est activé et verrouille le volume qui n'est donc pas monté.

Lance l'«Utilitaire de Disque» (dans la fenêtre des 4 Utilitaires macOS) > sélectionne le volume Untitled grisé (= non monté) > bouton : "Monter" > ton mot-de-passe de session dans le panneau qui le demande --> le volume Macintosh HD doit être affiché en noir plein, si remonté.

Dans ce cas --> reviens au Terminal et passe les 3 commandes. Poste les 3 tableaux retournés par ces commandes > sans oublier de le faire dans une fenêtre de code pour la lisibillité.

Re,

Diagnostic -->

  • volume monté en lecture & écriture > ré-installable ou restaurable
  • tous les dossiers-Système sont en place + le dossier macOS Install Data de la MÀJ plantée
  • le chemin de démarrage du volume pointe sur le démarreur boot.efi de l'OS d'installation du dossier macOS Install Data > et pas sur celui de l'OS en place

En résumé : le programme d'installation a juste changé le chemin de boot du volume avant de planter au redémarrage sans avoir agi. Tu as 99% de chances de pouvoir redémarrer l'OS et réouvrir ta session > à condition de passer une série de commandes préparatoires.

Commence par passer la commande :
Bloc de code: 
rm -rf /Volumes/"Macintosh HD"/"macOS Install Data"

  • mets les intitulés avec des "" ; pas d'espace entre HD" et /"macOS---
  • la commande supprime le dossier d'installation ; elle passe sans commentaire

Cela fait > repasse une commande :
Bloc de code: 
ls /Volumes/"Macintosh HD"

  • et poste la liste des dossiers --> pour vérifier que macOS Install Data a bien été supprimé.
 
Re,

Ok merci pour tes explications. Voila le résultat des commandes :

@ John

Le dossier à bien été supprimé.

À présent > il faut que tu passes la longue commande suivante -->
Bloc de code: 
bless --folder /Volumes/"Macintosh HD"/System/Library/CoreServices --file /Volumes/"Macintosh HD"/System/Library/CoreServices/boot.efi

  • voici comment tu vas t'y prendre pour la saisir commodément : par un copier-coller à rebours de cette page des forums MacGé --> dans la fenêtre du Terminal. Donc viens ici avec Safari > copie ma commande (déroule bien le tapis roulant horizontal jusqu'au boot.efi final) > quitte Safari > lance le Terminal > colle la commande dans la fenêtre > exécute-la.
  • La commande change le chemin de démarrage du volume > en le faisant pointer sur le démarreur boot.efi de l'OS en place.

La commande passée > repasse la commande informative :
Bloc de code: 
bless --info /Volumes/"Macintosh HD"

  • qui affiche le chemin de démarrage actif du volume

Poste le tableau retourné.
 
Re,

J'ai du recopier à la main la commande car apparemment j'ai besoin d'un accord parental pour aller sur le forum ... Lol enfin bref.

Voila le résultat des commandes :

Bloc de code: 
-bash-3.2# bless --folder /Volumes/"Macintosh HD"/System/Library/CoreServices --file /Volumes/"Macintosh HD"/System/Library/CoreServices/boot.efi
-bash-3.2# bless --info /Volumes/"Macintosh HD"
         493 => Blessed System File is <Preboot>/A672659C-5E4C-3235-9A40-53A34DA532A7/System/Library/CoreServices/boot.efi
          41 => Blessed System Folder is <Preboot>/A672659C-5E4C-3235-9A40-53A34DA532A7/System/Library/CoreServices
The blessed volume in this APFS container is "/Volumes/Macintosh HD"
-bash-3.2#
 
Parfait !

Il n'y a plus qu'à opérer les mises-à-jour des caches de démarrage --> passe les commandes :
Bloc de code: 
kextcache -u /Volumes/"Macintosh HD"
diskutil ap updatePreboot disk2s1

  • la 1ère met-à-jour le cache de boot prelinkedkernel chargé par le boot_loader : boot.efi au démarrage ; elle passe sans commentaire
  • la 2è met-à-jour les informations de pré-démarrage du volume Macintosh HD recelées dans le volume auxiliaire Preboot et exécutables par l'EFI ; elle retourne un affichage imposant

=> poste l'affichage retourné par la commandes 2.
 
Le Volume a été remonté. Voilà ce que j'ai obtenu avec les trois commandes :

@ John

Sans faute.

Va à : Menu  > Disque de démarrage > sélectionne Macintosh HD > redémarre dessus -->

  • bonne ré-ouverture de session !
 
@ nadj

Diagnostic -->

  • volume monté en lecture & écriture > ré-installable ou restaurable
  • tous les dossiers-Système sont en place + le dossier macOS Install Data de la MÀJ plantée
  • le chemin de démarrage du volume pointe sur le démarreur boot.efi de l'OS d'installation du dossier macOS Install Data > et pas sur celui de l'OS en place

En résumé : Tu es dans le même cas que John et donc je pronostique aussi pour toi 99% de chances de réouvrir ta session directement - après une série de commandes du même type que pour lui.

----------

Commence par passer la commande :
Bloc de code: 
rm -rf /Volumes/Untitled/"macOS Install Data"

  • mets "macOS Install Data" avec des ""
  • la commande supprime le dossier d'installation ; elle passe sans commentaire

Cela fait > repasse une commande :
Bloc de code: 
ls /Volumes/Untitled

  • et poste la liste des dossiers --> pour vérifier que macOS Install Data a bien été supprimé (NB : ne poste que le tableau retourné par cette commande)
 
Voici le tableau retourné :

Bloc de code: 
.DS_Store                Users
.DocumentRevisions-V100            Volumes
.HFS+ Private Directory Data?        bin
.IAProductInfo                cores
.OSInstallerMessages            dev
.PKInstallSandboxManager-SystemSoftware    etc
.Spotlight-V100                home
.Trashes                installer.failurerequests
.file                    net
.fseventsd                opt
.vol                    private
Applications                sbin
Library                    tmp
Network                    usr
System                    var
