小心,Mac OS也有类似万能密码!

上次系统故障,差点要重装系统。好在找到了一个方法同大家分享。


如果你有了一台苹果电脑,但还不清楚如何设置Firmware password(类似BIOS密码,默认是空的),那你还是要了解一下。

开机按Alt不松,进RecoveryHD, 再进终端,输入resetpassword,然后你就可以随便改掉系统用户的密码。所以有空在启用下吧!

 *当你忘记了系统用户密码,这个也能救你。


How to enable the Open Firmware Password

On any computer capable of firmware password protection (including Intel-based Macintosh computers), follow these steps:

  1. For Mac OS X v10.1 to v10.3.9, download and install the Open Firmware Password application, which you can get here.

    For Mac OS X v10.4.x, you must use the updated version that can be copied from the software installation disc (located at /Applications/Utilities/ on the disc).

    For Mac OS X v10.5.x, start from the Leopard Install DVD and choose Firmware Password Utility from theUtilities menu, then skip to step 5.
  2. Open the Open Firmware Password application.
  3. Click the icon to authenticate. Enter an administrator username and password when prompted.
  4. Click Change.
  5. Click to select the checkbox for "Require password to change Open Firmware settings", as shown below.
