sudo launchctl remove com.apple.spindump
sudo launchctl remove com.apple.analytics
sudo launchctl remove com.apple.touristd

sudo mv /usr/sbin/spindump /usr/sbin/backup.spindump
sudo mv /System/Library/PrivateFrameworks/Tourist.framework/Versions/A/Resources/touristd /System/Library/PrivateFrameworks/Tourist.framework/Versions/A/Resources/backup.touristd
后面两条改名字的不是必须的，但是自己觉得不放心就改了。

如果路径不对啥的，用下面的命令来找名为 XXXX 的文件。
sudo find / -name XXXX

一个口接一个雷电的 pcie 扩展卡，一个接万兆网卡，一个接 raid 卡直通阵列柜，这样 Mac （ mini ）也能做 nas+htpc 了。

@nyanyh 我这里也是 touristd 一直在使用网络数据，系统很多时候卡顿也是这三个家伙造成的，看描述应该是 beta 系统的信息收集用的。
