ML não instala por erro no acesso a HD
Aconteceu comigo e creio que com mais pessoas, a instalação do Mountain Lion nem mesmo começa e dá um erro que
o HD está com defeito.
O que resolveu no meu caso.
- Recuperei a ultima versão que tinha no Time Machine, acontece que ferrei tanto com as tentativas de
instalação que chegou uma hora que só tinha uma tela preta na minha frente, nem mesmo iniciava mais, então,
reiniciei com o Option pressionado pra escolher o disco de recuperação, e de lá recuperei o último backup
(+-3h).
