Donc tu fais un
diskutil rename disk0s2 "Macintosh HD"
puis tu quittes le terminal et tu demandes la réinstallation du système sur "Macintosh HD"

En espérant que ça passe.
 
Bonne idée. Par contre tu peux mettre à jour vers Sierra avant qu'il ne disparaisse ou au moins créer une clé d'installation.
Ton DDE étant largement assez grand pour faire un clone, on peut le repartitionner.
Peux-tu donner les retours, DDE connecté, de :
diskutil list
depuis le terminal (Applications/Utilitaires).
 
Oui ça serait super, par contre, je fais comment car je n'ai pas Sierra dans les achats.

On va commencer par renommer les partitions du DDE pour + de clarté :
diskutil rename disk2s2 Save_Macintosh_HD
puis
diskutil rename disk2s4 Clone
Puis tu redonnes les résultats de :
diskutil list

Après vérifications, tu peux télécharger Carbon Copy Cloner (version d'essai gratuite un mois) puis tu clones ton système actuel sur Clone.
Ceci fait, tu peux mettre à jour vers Sierra et si ok tu re-clones vers le même endroit.

Ensuite faudra tenter de récupérer tes données.

Super tu peux télécharger CCC, l'installer et lancer le clone vers Clone.
Ceci fait, tu fais la mise à jour vers Sierra. Si ok tu refais un clone de Sierra toujours vers Clone.

Ça va te prendre un peu de temps.:D
 
Donc tu es sur Sierra?
Il reste à récupérer tes données depuis Save_Macintosh_HD.

Tu sais ce que tu veux récupérer?
Mails, Musique, Photos?
