1，安全模式
方法很简单，就是启动时按shift键
据说如果按shift+v，能看到更多的信息
官方原文如下：

To start up into Safe Mode (to Safe Boot), do this:

1. Be sure the computer is shut down.
2. Press the power button.
3. Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone but not before.
4. Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).

2，用光盘启动
启动时按C键

3，启动进单用户模式
启动时按Option+S
