Kernel_task usando 300% de tempo de CPU, alta velocidade do ventilador e computador lento no MacBook Pro [duplicado]

15

Meu MacBook Pro ficou lento ultimamente. O monitor de atividades mostra que a tarefa do kernel está usando cerca de 300% da CPU. O ventilador está sempre ligado em alta velocidade.

Abaixo estão os detalhes do meu computador:

  • Macbook Pro de 13 polegadas, meados de 2012;
  • Processador Intel Core i5 de 2,5 GHz;
  • Memória 4 GB 1600 MHz DDR3;
  • Placa gráfica Intel HD Graphics 4000

Por favor, sugira algumas soluções.

Tentei redefinir o SMC algumas vezes.

Verifique esta solução a partir de macrumores:

  1. Vá para Sobre este mac sob a maçã no canto superior esquerdo e clique em Mais informações
  2. Clique no relatório do sistema
  3. Anote o que diz após o Identificador de modelo
  4. Vá para a pasta (isso pode ser alcançado no Finder usando Ir> Ir para pasta (cmd-shift-g)) /System/Library/Extensions/IOPlatformPluginFamily.kext/Contents/Plugins/ACPI_SMC_PlatformPlugin.kext/Contents/Resources
  5. Encontre o nome da etapa 3 e mova-o para uma pasta que você poderá encontrar novamente, se necessário.
  6. Reinicie e pronto

E se não houver um arquivo correspondente ao meu Identificador de modelo (MacBookPro10,1)?

@Gujamin, nesse caso, sudo mv /System/Library/Extensions/IOPlatformPluginFamily.kext/ ~funcionou para mim.
— Vivek Pandey
Também tive que fazer o que o Vivek postou logo acima (fui para o diretório no Finder, mudei para o desktop e pedi minha senha, que também funcionou) . Gostaria muito de saber o que causa isso.

Reinstale o sistema OS X usando um backup do Time Machine

A maneira mais fácil é reinstalar o OS X e restaurar usando um backup do Time Machine.

Primeiro, certifique-se de ter um backup do Time Machine.

O Time Machine funciona com qualquer disco rígido conectado ao seu computador usando USB, FireWire ou Thunderbolt.

  • Selecione o ícone Time Machine no menu.
  • Selecione Preferências do Open Time Machine ...
  • Se o Time Machine estiver desativado, ative o controle deslizante.
  • Selecione o disco que você deseja usar como um backup do Time Machine.
  • O Time Machine configurará o disco rígido para backups e iniciará automaticamente o primeiro backup em dois minutos.

Siga estas etapas se precisar apagar um disco antes de instalar o OS X:

  • Antes de começar, você precisa estar conectado à Internet.
  • Escolha menu Apple> Reiniciar e mantenha pressionadas as teclas Comando (⌘) e R enquanto o computador reinicia.
  • Selecione “Utilitário de Disco” e clique em Continuar. Selecione seu disco de inicialização na lista à esquerda e clique na guia Apagar.
  • No menu pop-up Formato, selecione Mac OS Extended (diário), digite um nome para o seu disco e clique em Apagar.
  • Depois que o disco foi apagado, escolha Utilitário de Disco> Sair do Utilitário de Disco.
  • Se você não estiver conectado à Internet, escolha uma rede no menu Wi-Fi no canto direito da barra de menus (no canto superior direito da tela). Selecione Reinstalar o Mac OS X, clique em Continuar e siga as instruções.

Para restaurar o conteúdo completo do seu disco rígido a partir de um backup do Time Machine:

  • Ligue o Mac e mantenha pressionadas as teclas de comando e R para entrar na Partição de recuperação. O seu Mac deve inicializar em uma tela que diz OS X Utilities.
  • Selecione Restaurar do Time Machine Backup e clique em Continuar.
  • Leia as informações na página Restaurar o sistema e clique em Continuar.
  • Selecione seu backup do Time Machine e clique em Continuar.
  • Selecione o backup mais recente do seu disco rígido e clique em Continuar. O seu Mac restaurará o backup do Time Machine; uma vez feito, ele será reiniciado.
