Bonjour a tous,

J'ai lancé hier apres midi la derniere maj de high sierra sur mon Imac Mid2011.
Il a redemarré pour l'installation, et je suis partit faire autre chose.
Je l'ai retrouvé sur un ecran noir ce matin...
J'ai essayé reset pram et smc sans resulats.
Au chargement de la pomme il ne va pas jusqu'au bout, puis ecran noir, avec toute les 3 ou 4 seconde l'icone de chargement qui part et reviens.

Comment solutionner ce probleme ?
Merci par avance car je desespere...
 
Si ça peut te rassurer, j'ai subi à peu près la même mésaventure il y a quelques jours (x-ième màj de HS, iMac "late" 2012). Finalement j'ai tout éteint et le lendemain la màj a fonctionné.
Je n'ai rien compris, pourtant j'ai presque 30 ans de Macs derrière moi :bored:

Salut

As-tu des sauvegardes de cet iMac?
Sinon que te renvoient :
ls -l /Volumes/"Macintosh HD"
et
df -H
 
Non malheuresement pas de sauvegarde... au pire des cas au moins pouvoir transferer les fichier sur un dd externe.

voila ce que sa me donne :

Salut toreto

En ce qui concerne ce disque -->

  • c'est bien celui d'un DDE neuf : on peut l'effacer pour le paramétrer "Mac" ?
 
oui tout a fait, on peut l'effacer, je l'ai acheté expres pour sa :)

que doit je faire ?
 
Passe la commande :
Bloc de code:
diskutil eraseDisk jhfs+ Clone disk20

  • qui initialise "Mac" le disque du DDE en remontant un volume intitulé Clone

Reposte ici le tableau retourné par un :
Bloc de code:
diskutil list

pour vérification.
 
voila pour toi :)
je te remercie de m'apporter ton aide en tout cas !

-bash-3.2#
 
Alors tout est prêt.

Tu as 2 commandes à passer -->

- par la commande :
Bloc de code:
caffeinate -dimsu &

  • tu empêches ton Mac de s'endormir pendant l'opération

- par la commande :
Bloc de code:
cp -av /Volumes/"Macintosh HD"/* /Volumes/Clone
(mets bien "Macintosh HD" entre "" ; il n'y a pas d'espace entre HD" et /*)

  • tu clones le contenu de Macintosh HD dans Clone
  • tu vas voir défiler autant de lignes que de fichiers copiés

=> attends l'arrêt du défilé et le ré-affichage de l'invite de commande -bash-3.2# en signe de complétion.

Tu n'auras qu'à faire signe, alors.
