mac唤醒后运行脚本：Sleepwatcher
Sleepwatcher是一个Mac OS X后台守护程序，可以在各种电源相关事件发生时触发脚本运行，例如笔记本电脑正在睡眠或唤醒，屏幕变暗或电源适配器连接或断开连接。
在我的个人笔记本电脑上，我在Sleepwatcher中设置了一个AppleScript，可在每次笔记本电脑进入睡眠状态时将音频静音。这是为了防止在会议和课堂上意外播放音频。
建立
下面是我编写的sleepwatcher安装脚本，它将自动安装为系统智能守护程序。

该脚本首先删除计算机上的任何旧版本的sleepwatcher。他们转而下载软件包并将文件复制到适当的位置。它加载启动守护进程然后创建两个文件，/etc/rc.sleep并且/etc/rc.wakeup。当笔记本电脑要睡觉或醒来时，它们会在各自的时间运行。
我的个人/etc/rc.wakeup剧本如下所示。它所做的只是运行简短的AppleScript命令将音量设置为零。要在您的计算机上获得此功能，只需将以下代码复制到您自己的计算机上/etc/rc.wakeup。

#!/bin/sh osascript -e 'set volume 0' |
sleepwatcher的其他可能用途包括在唤醒时更新DNS记录，为用户打开特定应用程序，当然还可以运行用户选择的另一个脚本。

我的黑苹果更新系统后，睡眠唤醒后网卡不能联网，于是我在/etc/rc.wakeup里加入以下代码

#!/bin/sh ifconfig en0 down ifconfig en1 down ifconfig en0 up ifconfig en1 up |
让网卡重启一遍。希望对遇到我一样的总是的朋友有帮助。
