Performing a Clean Installation
This section provides instructions for what is commonly called a “clean installation” of system
software. Performing a clean installation is more complicated than a standard installation, but
it is sometimes the best way to solve a persistent problem. A clean installation gives you a
fresh start with system software.
When you install system software using a clean installation, the Installer creates a new System
Folder on your hard disk. The old System Folder is renamed Previous System Folder. Since
your computer has a new System Folder, after a clean installation you must reinstall custom
fonts, extensions, and control panels that you’ve added to your system or that came with
utility or application programs. You will also need to reset modem settings in
communications software programs you are using.
Note: Though application programs are not replaced or changed, some require system
software components that are removed from the System Folder during a clean installation.
You may need to reinstall these applications after you perform a clean installation.
