Problème Reparation de Permissions Macbook Pro Maverick...

Bonjour tout le monde,

Il y a quelque temps j'ai changé le mdp de mon macbook pro. Il contenait des symboles,majuscules,chiffres, bref un mdp de killer qui, lorsque j'ai essayé de le rentrer pour la premiere fois après redémarrage, n'a pas été reconnu. J'ai donc du faire une manip pour pouvoir changer mon mot de passe en passant par l'equivalent du mode sans échec x) Mais résultat a chaque fois que je lance safari j'ai un message d'erreur a propos des keychains. Pour couronner le tout, lorsque je lance une reparation des permissions avec Onyx, voila ce que l'on m'affiche:

Merci de me dire ce que je dois faire..
Ps: Je me rappelle de l'ancien mot de passe de killer si ca peut aider a unlock les keychains ou je sais pas quoi !
