Many people have reported this problem. Seems to be related to unsigned kext files.
Examples: VirtualBox, Soundflower, Parralels
Problem was reported already in beta version.
Why Apple didn't correct is a big question.... Apple gets sloppy?
We just have to wait for a solution.
Bonjour,
Après l'installation de Mac OS X, je l'ai utilisé. Ce matin j'ai allumé mon ordinateur, et au bout de quelques secondes sur l'écran est venu des bandes de carré noir avec l'écran figé.
La seule combinaison qui fonctionne et commande plus R. J'ai réinstaller OS X par-dessus celui qui était installé j'ai pu à nouveau utiliser mon ordinateur sans aucun problème je l'ai éteint et dans l'après-midi, je l'ai rallumé et j'ai à nouveau le même problème écran figé avec des carrés noirs en ligne sur tous les écrans mon ordinateur est un iMac début 2009.
Depuis que j'ai eu cet ordinateur, je n'ai jamais eu le moindre problème avec le système est une solution à me proposer afin de régler ce problème. Pourrait-il s'agir d'un problème de piles ?.
Merci d'avance pour votre aide
