Oui j'ai vu ton édit mais c'est irrémédiable manifestement sauf a tout réinstallerC’est lent parce que tu travailles exclusivement sur le HDD voir l’édit de mon post #17
Bonjour @macomaniac , qu'entends tu par session de départ ? car oui le mac se lance sans problème hormis une lenteur excessive.Bonjour.
Le Fusion Drive initial était de type apfs (= nouveau type > et pas de type CoreStorage = ancien type). C'est la règle pour l'installation des OS Mojave ou Catalina. Le type CoreStorage de Fusion Drive n'est valide que pour tout OS avant Mojave (jusqu'à High Sierra compris - donc).
- le problème au départ ne consistait qu'à supprimer une partition de type apfs > qui a été reformatée avec un volume Untitled classique. Il suffisait alors de supprimer cette partition et de récupérer cet espace au Conteneur apfs du Fusion Drive.
Je n'ai pas suivi les péripéties ensuite (je viens de survoler le fil). Est-ce que la session de départ dans le volume Macintosh HD s'ouvre toujours ?
