Ho un MacBook Pro di metà 2012 e aggiornato a OS X Yosemite poche settimane fa. Diverse volte da allora la GPU si è schiantata dove posso ancora muovere il cursore del mouse sullo schermo e ascoltare l'audio, ma tutto il resto sullo schermo non risponde. Sono riuscito a rimediare solo riavviando la macchina.
C'è un modo per impedire che ciò accada?
