Kernel_task che utilizza il 300% del tempo di CPU, l'alta velocità della ventola e il computer lento in MacBook Pro [duplicato]

15

Il mio MacBook Pro è diventato lento ultimamente. Il monitor delle attività mostra che il task del kernel utilizza circa il 300% della CPU. Il ventilatore è sempre acceso ad alta velocità.

Di seguito sono riportati i dettagli del mio computer:

  • Macbook Pro da 13 pollici, metà 2012;
  • Processore Intel Core i5 da 2,5 GHz
  • Memoria 4 GB 1600 MHz DDR3;
  • Grafica Intel HD Graphics 4000

Si prega di suggerire alcune soluzioni.

Ho provato a reimpostare SMC alcune volte.

Controlla questa soluzione dai macrumors:

  1. Vai a Informazioni su questo mac sotto la mela in alto a sinistra e fai clic su Ulteriori informazioni
  2. Fai clic sul rapporto di sistema
  3. Prendi nota di ciò che viene detto dopo l'Identificatore del modello
  4. Vai alla cartella (questo può essere ottenuto in Finder utilizzando Vai > Vai alla cartella (cmd-shift-g)) /System/Library/Extensions/IOPlatformPluginFamily.kext/Contents/Plugins/ACPI_SMC_PlatformPlugin.kext/Contents/Resources
  5. Trova il nome dal passaggio 3 e spostalo in una cartella che puoi trovare di nuovo se necessario.
  6. Riavvia e hai finito

Reinstallare il sistema OS X utilizzando un backup di Time Machine

Il modo semplice è reinstallare OS X e ripristinare utilizzando un backup di Time Machine.

Prima fai in modo che Shure abbia un backup di Time Machine.

Time Machine funziona con qualsiasi disco rigido collegato al computer tramite USB, FireWire o Thunderbolt.

  • Seleziona l'icona Time Machine dal menu.
  • Seleziona le Preferenze di Open Time Machine ...
  • Se Time Machine è disattivato, attiva il dispositivo di scorrimento.
  • Seleziona il disco che vuoi utilizzare come backup di Time Machine.
  • Time Machine imposterà il disco rigido per i backup e avvierà automaticamente il primo backup entro due minuti.

Utilizzare questa procedura se è necessario cancellare un disco prima di installare OS X:

  • Prima di iniziare, è necessario essere connessi a Internet.
  • Scegli il menu Apple > Riavvia, quindi tieni premuti i tasti Comando (⌘) e R mentre il computer si riavvia.
  • Seleziona "Utility Disco", quindi fai clic su Continua. Seleziona il tuo disco di avvio dall'elenco a sinistra, quindi fai clic sulla scheda Cancella.
  • Dal menu a comparsa Formato, seleziona Mac OS Esteso (Journaled), digita un nome per il tuo disco, quindi fai clic su Cancella.
  • Dopo che il disco è stato cancellato, scegli Utility Disco > Esci da Utility Disco.
  • Se non sei connesso a Internet, scegli una rete dal menu Wi-Fi nell'angolo destro della barra dei menu (nell'angolo in alto a destra dello schermo). Seleziona Reinstalla Mac OS X, fai clic su Continua, quindi segui le istruzioni.

Per ripristinare il contenuto completo del disco rigido da un backup di Time Machine:

  • Accendi il Mac e tieni premuto il comando e i tasti R per accedere alla partizione di ripristino. Il tuo Mac dovrebbe avviarsi su una schermata che dice OS X Utilities.
  • Seleziona Ripristina da Time Machine Backup e fai clic su Continua.
  • Leggi le informazioni sulla pagina Ripristina il tuo sistema e fai clic su Continua.
  • Seleziona il backup di Time Machine e fai clic su Continua.
  • Seleziona il backup più recente del tuo disco rigido e fai clic su Continua. Il Mac ripristinerà quindi il backup di Time Machine; una volta terminato, si riavvierà.
