Initial Installation
Initial Installation
Although secure configuration of an existing Mac OS X installation is possible,
securely configuring a fresh installation is much simpler. Although this may not
always be practical, it is the recommended way to configure Mac OS X. This section
details the steps involved in such an installation. If it is not possible to re-install the
system, much of this chapter will not be applicable. The guidance in this chapter can
still be used, however, to determine any differences between the previous installation
and the recommended one. Wherever differences exist, the previous installation
should be modified to match the recommended one; this may entail deleting
installed packages, deleting registration information, changing an administrative
account name, installing updates, and fixing disk permissions. This guide does not
provide instructions on making these types of modifications to a previously installed
system. Also, administrators should be aware that applying these recommendations
to an existing system might cause the system to operate incorrectly.

2. Enter the Open Firmware password when prompted.
3. At the Open Firmware prompt (“>”) enter:

up to an alternate location before beginning this installation. When backing up and
restoring any information, the following guidelines should be used:
