macOS Big Sur : comment repasser \u00e0 macOS Catalina<\/h3>\n

Il est possible de revenir sur macOS Catalina sans effacer compl\u00e8tement votre disque dur et r\u00e9installer proprement le syst\u00e8me d'exploitation. Mais on vous conseille tout de m\u00eame de bien tout sauvegarder avant la proc\u00e9dure :<\/p>\n

\n
1. Allez dans Pr\u00e9f\u00e9rences syst\u00e8me > Mises \u00e0 jour<\/strong><\/li>\n
2. Cliquez sur D\u00e9tails<\/strong> dans la partie gauche<\/li>\n
3. Cliquez sur Revenir aux param\u00e8tres par d\u00e9faut<\/strong><\/li>\n
4. Cliquez ici pour t\u00e9l\u00e9charger le programme d'installation de macOS Catalina \u00e0 partir du Mac App Store<\/li>\n
5. Ignorez les messages d'avertissement<\/li>\n
6. Une fois t\u00e9l\u00e9charg\u00e9, lancez l'installateur pour installer macOS Catalina \u00e0 la place de la beta<\/li>\n<\/ol>\n

   Si cette m\u00e9thode ne fonctionne pas, il faudra obligatoirement effacer votre disque dur et refaire une installation propre de macOS Catalina.<\/p>\n
