停止nsurl…..

launchctl unload /System/Library/LaunchDaemons/com.apple.nsurlstoraged.plist
launchctl unload /System/Library/LaunchAgents/com.apple.nsurlsessiond.plist
sudo launchctl unload /System/Library/LaunchDaemons/com.apple.nsurlsessiond.plist
sudo launchctl unload /System/Library/LaunchDaemons/com.apple.nsurlstoraged.plist

禁用 在应用程序-实用工具-终端 中输入如下代码回车即可：

sudo launchctl unload -w /System/Library/LaunchDaemons/com.apple.metadata.mds.plist

如果想要再次开启Spotlight，那么在终端中再次执行下面的代码：

sudo launchctl load -w /System/Library/LaunchDaemons/com.apple.metadata.mds.plist
