Bom dia!

Meu Macbook ao ligar fica na tela cinza por 40 minutos antes de aparecer o logo e iniciar o OSX. Ao iniciar, o bluetooth não é mais reconhecido, e no log fica um erro em loop, onde o mac tenta encontrar a porta USB.

Gostaria de saber se tem alguma forma de desativar essa porta no kernel, ou alguma tecla para quando ligar o computar ignorar este erro, e iniciar o osx?

Erro que fica dando no console:

Já tentou uma nova instalação? Ou não chega  nem a dar essa opção no boot?

Ele chega da o Boot depois de muito tempo na tela cinza, só que sme o bluetooth.

Já troquei o HD, fiz o reset do SMC, PRam. O pessoal de uma assistencia falou que é a porta do bluetooth no hub usb que está com curto, mas cobram quase o preço do macbook para arrumar. Por isso penso em desativar essa porta, dai acredito que irá iniciar normalmente.
