While you can certainly spend money on firewall applications for your Mac—the aforementioned Norton Security application will set you back a minimum of $45 per year—your Mac, no surprise. We recently installed a new ZyWall firewall in the office, and it's using basic settings to block personal sites, inappropriate content, social media, etc. We also discovered that it's blocking the App Store, which presents a problem as our company Macs can no longer get their security and software updates (especially important for my boss!).
Mac OS X has a built-in firewall that is not running by default. This will show you how to start or stop the OS X firewall.
Directions for 10.7 and newer:
To open the Firewall control panel:
- Go to Apple menu, System Preferences

Here you can either Start or Stop the firewall by clicking a button. We recommend you turn your firewall on. After starting the firewall, you will then be able to click the Firewall Options... button for more advanced configuration if you wish.
- Click Block all incoming connections to enable very strict firewall rules but be aware this will disable any sort of sharing from your computer. If you would like more control over the firewall- please follow the below items...
- Uncheck Block all incoming connections to enable custom firewall rules. Generally as applications and services try to connect to your computer, you will be given the option to either allow or deny these connections individually. If you choose this option you can also choose to check either of the bottom check boxes regarding Allowing signed applications to connect and Enabling stealth mode.
- Click the OK button when you are done and then close the System Preferences window.
