goldenapp 忘记在哪找的了，直接贴出来吧...
前提是你有原始的dmg或者.app我是在osx下面转换的，然后vmware里面装的，可以用
只是vmware，多数要选默认项，别去改USB3支持什么的，不然鼠标什么的不能用。

#!/bin/bash

# This executable converts a Mavericks .app (which allows to upgrade a machine
# from Mac OS 10.6.7+ to Mavericks) into a Mavericks .dmg (which allows to
# install Mavericks from scratch on a machine).
#
# It has been tested with "Install OS X 10.9 Developer
Preview.app" (build
# 13A476u).

set -e
# The first argument is the path to the .app bundle (the input of the
# executable).

# The second argument is the path to the .dmg file (the output of the
# executable), which must end with ".dmg".

#
# The problem: /System/Installation/Packages inside /BaseSystem.dmg inside
# "$inputApp"/Contents/SharedSupport/InstallESD.dmg is a dangling symlink,
# which prevents installing Mavericks from scratch.
# The solution: Replace the symlink with the /Packages directory inside
# "$inputApp"/Contents/SharedSupport/InstallESD.dmg.
