CPU负载突然飙升，如截图：

根本原因，大家从各种博主上已知晓，现在提供自己的解决办法，亲测有效

一、设置开机自动禁用温度管理守护进程

1.创建脚本文件

mkdir -p ~/Scripts

touch ~/Scripts/disable_thermald.sh

chmod +x ~/Scripts/disable_thermald.sh

2.编辑脚本内容

vim ~/Scripts/disable_thermald.sh

复制代码

   #!/bin/bash
   
   # 等待30秒，确保系统完全启动
   sleep 30
   
   # 禁用温度管理守护进程
   sudo launchctl unload -w /System/Library/LaunchDaemons/com.apple.thermald.plist
   sudo launchctl unload -w /System/Library/LaunchDaemons/com.apple.thermalmonitord.plist
   
   # 可选：记录日志
   echo "$(date): 已禁用温度管理守护进程" >> ~/Scripts/thermald_log.txt

3.创建启动项plist文件

touch ~/Library/LaunchAgents/com.user.disablethermald.plist

复制代码

   <?xml version="1.0" encoding="UTF-8"?>
   <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
   <plist version="1.0">
   <dict>
       <key>Label</key>
       <string>com.user.disablethermald</string>
       <key>ProgramArguments</key>
       <array>
           <string>/bin/bash</string>
           <string>-c</string>
           <string>~/Scripts/disable_thermald.sh</string>
       </array>
       <key>RunAtLoad</key>
       <true/>
   </dict>
   </plist>

4.加载启动项

launchctl load ~/Library/LaunchAgents/com.user.disablethermald.plist
