Non, c'est la nouvelle structure du format APFS dans un disque dur. D'un côté il y a Macintosh HD qui contiendra macOS Catalina (les fichiers système) et qui sera quasiment intouchable, de l'autre coté Macintosh Données contenant les données de l'utilisateur. Pour le moment ce n'est pas facile à comprendre, mais c'est une sécurité supplémentaire pour protéger macOS de son utilisateur.Ce serait donc bien Catalina qui m'aurait foutu le bazar. Merci pour l'info. rapide je teste et je rends compte.
