MacBook Pro中使用300％CPU时间，高风扇速度和慢速计算机的Kernel_task [重复]

15

我的MacBook Pro最近变慢了。活动监视器显示内核任务正在使用大约300％的CPU。风扇始终保持高速运转。

以下是我的计算机的详细信息：

  • Macbook Pro 13英寸，2012年中；
  • 处理器2.5 GHz Intel Core i5;
  • 内存4 GB 1600 MHz DDR3;
  • 图形Intel HD Graphics 4000

请提出一些解决方案。

我尝试过几次重置SMC。

从macrumors 检查此解决方案：

  1. 转到左上方苹果下的关于本机，然后单击更多信息。
  2. 点击系统报告
  3. 记下Model Identifier后的内容
  4. 转到文件夹（可以使用转到>转到文件夹（cmd-shift-g）在Finder中实现） /System/Library/Extensions/IOPlatformPluginFamily.kext/Contents/Plugins/ACPI_SMC_PlatformPlugin.kext/Contents/Resources
  5. 在第3步中找到名称，然后将其移动到一个文件夹，如果需要，可以再次找到该文件夹​​。
  6. 重新启动就完成了

使用Time Machine备份重新安装OS X系统

简单的方法是重新安装OS X并使用Time Machine备份进行还原。

首先确保您有Time Machine备份。

Time Machine可与使用USB，FireWire或Thunderbolt连接到计算机的任何硬盘一起使用。

  • 从菜单中选择Time Machine图标。
  • 选择打开Time Machine偏好设置...
  • 如果Time Machine关闭，请将滑块设置为on。
  • 选择要用作Time Machine备份的磁盘。
  • Time Machine将设置硬盘驱动器进行备份，并将在两分钟内自动开始第一次备份。

如果在安装OS X之前需要擦除磁盘，请使用以下步骤：

  • 开始之前，您需要连接到Internet。
  • 选择“苹果”菜单>“重新启动”，然后在计算机重新启动时按住Command（⌘）和R键。
  • 选择“磁盘工具”，然后单击“继续”。从左侧列表中选择启动磁盘，然后单击“擦除”选项卡。
  • 从“格式”弹出菜单中，选择“ Mac OS扩展（日志式）”，为磁盘键入一个名称，然后单击“擦除”。
  • 擦除磁盘后，选择“磁盘工具”>“退出磁盘工具”。
  • 如果未连接到Internet，请从菜单栏右上角（在屏幕的右上角）的Wi-Fi菜单中选择一个网络。选择“重新安装Mac OS X”，单击“继续”，然后按照说明进行操作。

要从Time Machine备份还原硬盘驱动器的完整内容，请执行以下操作：

  • 打开Mac的电源，然后按住Command和R键进入恢复分区。您的Mac应该启动到显示OS X实用程序的屏幕。
  • 选择从Time Machine备份还原，然后单击继续。
  • 阅读“还原系统”页面上的信息，然后单击“继续”。
  • 选择您的Time Machine备份，然后单击继续。
  • 选择硬盘的最新备份，然后单击继续。然后，您的Mac将恢复Time Machine备份；一旦完成，它将重新启动。
