MacBook Pro에서 300 % CPU 시간, 높은 팬 속도 및 느린 컴퓨터를 사용하는 Kernel_task [중복]

15

MacBook Pro가 최근 느려졌습니다. 활동 모니터는 커널 작업이 약 300 %의 CPU를 사용하고 있음을 보여줍니다. 팬은 항상 고속으로 켜져 있습니다.

아래는 내 컴퓨터의 세부 사항입니다 :

  • 2012 년 중반 Macbook Pro 13 인치;
  • 프로세서 2.5GHz Intel Core i5;
  • 메모리 4GB 1600MHz DDR3;
  • 그래픽 인텔 HD 그래픽 4000

몇 가지 해결책을 제안하십시오.

SMC를 몇 번 재설정하려고했습니다.

Time Machine 백업을 사용하여 OS X 시스템 재설치

쉬운 방법은 OS X를 다시 설치하고 Time Machine 백업을 사용하여 복원하는 것입니다.

먼저 Time Machine 백업이 있는지 확인하십시오.

Time Machine은 USB, FireWire 또는 Thunderbolt를 사용하여 컴퓨터에 연결된 모든 하드 디스크와 작동합니다.

  • 메뉴에서 Time Machine 아이콘을 선택하십시오.
  • Open Time Machine 환경 설정 ...을 선택하십시오.
  • Time Machine이 꺼져 있으면 슬라이더를 켬으로 설정하십시오.
  • Time Machine 백업으로 사용할 디스크를 선택하십시오.
  • Time Machine은 백업을 위해 하드 드라이브를 설정하고 2 분 내에 첫 번째 백업을 자동으로 시작합니다.

OS X를 설치하기 전에 디스크를 지워야하는 경우 다음 단계를 사용하십시오.

  • 시작하기 전에 인터넷에 연결되어 있어야합니다.
  • Apple 메뉴> 재시동을 선택한 다음 컴퓨터가 재시동되는 동안 Command (⌘) 및 R 키를 누르십시오.
  • “Disk Utility”를 선택한 다음 Continue를 클릭하십시오. 왼쪽 목록에서 시동 디스크를 선택한 다음 지우기 탭을 클릭하십시오.
  • 포맷 팝업 메뉴에서 Mac OS 확장 (저널링)을 선택하고 디스크 이름을 입력 한 다음 지우기를 클릭하십시오.
  • 디스크가 지워지면 디스크 유틸리티> 디스크 유틸리티 종료를 선택하십시오.
  • 인터넷에 연결되어 있지 않은 경우 메뉴 막대의 오른쪽 모서리 (화면 오른쪽 상단)에있는 Wi-Fi 메뉴에서 네트워크를 선택하십시오. Mac OS X 재설치를 선택하고 계속을 클릭 한 다음 지침을 따르십시오.

Time Machine 백업에서 하드 드라이브의 전체 내용을 복원하려면

  • Mac의 전원을 켜고 명령과 R ​​키를 누른 상태에서 복구 파티션을 시작하십시오. Mac이 OS X 유틸리티라는 화면으로 부팅해야합니다.
  • Time Machine 백업에서 복원을 선택하고 계속을 클릭하십시오.
  • 시스템 복원 페이지의 정보를 읽고 계속을 클릭하십시오.
  • Time Machine 백업을 선택하고 계속을 클릭하십시오.
  • 하드 디스크의 최신 백업을 선택하고 계속을 클릭하십시오. 그러면 Mac이 Time Machine 백업을 복원합니다. 완료되면 다시 시작됩니다.
