Install and Configure Norton Personal Firewall: Mac OS X 10.0 - 10.3

This document describes how to install and configure the Norton Personal Firewall for Mac OS X 10.0 through Mac OS X 10.3. The Norton Personal Firewall helps protect your computer from malicious attacks, so it is extremely important to install and update this software regularly.

IMPORTANT: Norton Personal Firewall works ONLY for OS X 10.0 through OS X 10.3 (Panther). If you have OS X 10.4 (Tiger), Norton Personal Firewall will not work.

Before You Begin

To use Norton Personal Firewall for Macintosh, you need the following:

  • A machine running Macintosh OS X 10.0 through OS X 10.3. Note that OS X 10.4 WILL NOT work with Norton Personal Firewall.
  • The Norton Personal Firewall installer from the BevoWare download site
  • 25 MB of available hard disk space, 128 MB of RAM
  • An active Internet connection (if you plan to use the product's auto-update function)

Before you install Norton Personal Firewall:

  • Close all programs on your machine, so you won't lose work when you restart the machine during this installation.
  • Log in with a user name and password for an account on your system with administrative privileges.
  • Uninstall any other firewall applications. If you have already installed Norton AntiVirus, you must disable it before installing Norton Personal Firewall.

Installing Norton Personal Firewall

To install Norton Personal Firewall from the BevoWare download site:

OS X 10.2 USERS: If you did not choose to run LiveUpdate when installing Norton AntiVirus or Norton Personal Firewall, you may see this error message when you reboot:

  The program you are using needs to use a system file
  that may reduce the security of your computer.

Click DON'T USE when prompted to fix the problem. Then, run LiveUpdate to update both Norton AntiVirus and Norton Personal Firewall. This will eliminate the error message.

    • Allow these addresses. Limits access to specific systems or networks. If you select this option, click New to specify an address, address range, or network.
