禁用spotlight

Leopard上的spotlight纯属鸡肋，很少使用，而且还影响系统速度，不如直接禁用：
1. 停止spotlight程序

# 停止当前用户
launchctl unload /System/Library/LaunchAgents/com.apple.Spotlight.plist
# 停止所有用户
sudo launchctl unload -w /System/Library/LaunchAgents/com.apple.Spotlight.plist

2. 停止background server

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

3. 删除index文件

sudo find / -iname '.Spotlight-V100' -type d -maxdepth 3 -print0 
| xargs -0 -t -n1 sudo rm -rf

4. 恢复方法, 以后想恢复了再load回来

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