Macbook Air (Yosemite) trava enquanto assiste a vídeos

Há cerca de uma semana, o meu Macbook (Air early 2014) tem falhado sempre que o tenho utilizado para ver vídeos online (Youtube etc.)

Eu dei uma olhada nos logs de eventos e encontrei várias entradas de kernel panic que, acredito, estão apontando para a placa gráfica / drivers integrados.

Alguém poderia confirmar isso e, possivelmente, dar uma solução para o problema?

este não é um problema com a GPU. O relatório diz que isso foi um problema com:

com.apple.WebKit

WebKit é o "software" que o Safari usa para renderizar / desenhar a página da web.

Este parece ser um problema originado nas estruturas gráficas do OS X, o que significa que é um problema de software. Isso pode ser um bug no Safari ou algo pode estar causando isso.

Eu recomendo usar outro navegador e ver se isso acontece. Se isso acontecer em outro navegador, pode ser um problema com o OS X e talvez seja necessário executar mais algumas etapas.

Se isso acontecer apenas no Safari, recomendo desativar todas as extensões para ver se uma delas está causando o problema.

Pelo que eu posso dizer, enquanto o WebKit estava desenhando a imagem, algo "entupiu" o processo. Isso significa que é provavelmente uma extensão.

Esse log não mostra problemas com a GPU.

Os problemas vêm do navegador que você está usando (Safari).

Primeiro tente assistir sem fones de ouvido conectados.

Em seguida, tente usar um navegador diferente (Firefox, Chrome ...)

Para verificar se a GPU está bem, reproduza um vídeo que você baixou (do seu disco rígido).

Se acima estiver correto, vamos corrigir seu Safari ou ficar com outra opção de navegador
