[Cremat]

Quando fui reinstalar o Mac OS no Macbook Pro apresentou a seguinte mensagem de erro após ter selecionado a lingua de instalação, algum pode me ajudar?

Aparentemente a mídia está com defeito. O check do OSInstall.mpkg não deveria dar com erro. Tente limpar a mídia com um pano seco, lentamente, e tente novamente.
