如何制作一个Mac OS X的完整的USB安装盘

一般情况下，我们制作Mac OS X的USB安装盘，是通过磁盘管理的恢复功能进行制作。 这样制作出来的安装盘在大部分的Mac机器上都是可以安装的。 但是我曾经碰到安装不了的情况，总是提示“Can't download the additional components needed to install Mac OS X”，Mac10.6, 10.7, 10.8都试了，就是安装不了，花了我好几天的时间，终于发现一个新的制作方法，它可以制作完整的安装包。 用这个安装包就可以成功的安装。

This method allows you to create a USB that allows for quick installation and clean installs.

This method will provide you with the "classic" OSX installer, with disk utility and whatnot available before starting the install. The installation will be a LOT faster.

*Download the installer from the app store.

*Right-click installer -> "Show Package Contents"

*Contents -> Shared Support -> InstallESD.dmg (open it/mount it)

*Open the terminal and input this command:

Quote:

open /Volumes/Mac\ OS\ X\ Install\ ESD/BaseSystem.dmg

*Now open Diskutility and "restore" BaseSystem.dmg to your USB drive.

***PLEASE NOTE THIS REQUIRES YOUR USB HAS A GUID PARTITION TABLE***

[Changing partition table to GUID]





[Restoring the DMG]

*Now open your newly restored USB drive

*System -> Installation

*Delete the link called "Packages" and then create a new folder with the same name



*Open the terminal again and copy this to it:

Quote:

open /Volumes/Mac\ OS\ X\ Install\ ESD/Packages

*Copy everything in this folder to the "Packages" folder you created on your USB.





**Note this stage might take a while**



Hurray you now have a working installer!
