Reinstalling Your Computer’s Software
If you are having problems with the system software or applications that came with your
computer, you can replace software in the following ways:
m reinstall system software—if you encounter system software problems or you want to add
or remove system software components
m reinstall individual applications—if you inadvertently erased or are having problems with
an application on your hard disk
m restore your hard disk’s original contents—if you want your computer to have its original
system software, factory settings, and applications
Reinstalling System Software
The Mac OS Install application lets you reinstall the Mac OS (or specific components of the
Mac OS) on your computer. This application is located on the software install CD that came
with your computer.
Note: If your computer came with additional software installed, see the Read Me document
on your software install CD for information about reinstalling this software and any custom
system software settings on your computer. If you are using a system software CD to reinstall
the Mac OS, you can’t use it to reinstall any additional software.
Before Installing System Software
Before you begin the installation, do the following:
m Customized settings and preferences: If possible, make a note of any preferences or
settings in control panels and applications so you can easily reset them after you restore
or reinstall your software.
Note: If you are having problems with your computer, you may not be able to open files
with preferences or customized settings.
