Mise à jour impossible MacBook Pro.


Recommended Posts


Suite à un bug, j’ai restauré mon MacBook Pro unibody mi 2012.

Il a installé Mac OS Lion.

Le problème c’est que je ne peux rien mettre à jour. 

Il refuse de mettre à jour safari ainsi que de se connecter à AppStore (version trop anciennes) ainsi qu’au support Apple.

Toutes les versions logicielles sont trop anciennes. 

Pourriez-vous m’expliquer comment effectuer les mises à jour ?
