Step-by-Step Guide: How to Allow Chrome to Access the Network in Your Firewall on Mac


Allowing your internet browser, like Google Chrome, to bypass your firewall’s constraints is integral for a seamless browsing experience. However, to maintain a secure digital environment, understanding your Mac’s firewall settings and how Chrome interacts with them is crucial. Firewall-related issues on your Mac can cause a series of problems, from blocking specific sites to stopping Chrome from accessing the internet altogether.

Understanding Firewall on Mac

Before we delve into the specifics of configuring your Mac’s firewall to allow Chrome, it’s critical to understand what a firewall is and its importance. A firewall is a network security system that monitors and controls the incoming and outgoing network traffic based on predetermined security rules. It is the first line of defense against malicious software, protecting your Mac from potentially harmful entities that may threaten your data.

Whenever you use Chrome, it interacts with the firewall, requesting access to the network, and the firewall either grants or refuses this request based on its current settings.

Preliminary Steps

Before modifying your firewall settings, determine if it is indeed necessary to allow Chrome to bypass the firewall. Check if Chrome and your firewall’s versions are compatible. Additionally, it is advisable to back up any essential files to prevent any potential data loss during the process.

Step-by-step Guide on Allowing Chrome to Access the Network in Your Firewall

Accessing System Preferences

To start, click on the Apple menu on your desktop. From the dropdown menu, select ‘System Preferences.’

Navigating to the Security and Privacy Settings

Once in the System Preferences window, click on the ‘Security & Privacy’ option to access your Mac’s security settings.

Unveiling the Firewall Settings

Click on the ‘Firewall’ tab. If necessary, enter your admin password to unlock the settings and make changes.

Adding Chrome to the List of Applications Allowed

Next, click on the ‘+’ button underneath the ‘Firewall Options…’. Locate Google Chrome in the application list and click ‘Add.’ Chrome is now allowed to receive incoming connections.

Testing the New Firewall Settings

Finally, close the ‘System Preferences’ window and test your new settings by accessing the internet via Google Chrome.

Advanced Firewall Settings

Advanced Firewall settings provide additional security options for your Mac. Enabling ‘Stealth Mode’ makes your computer invisible on public networks. Additionally, you can configure extra firewall options to fine-tune your network’s security needs.

Troubleshooting Common Issues

If Chrome persists in failing to access the network, consider making exceptions in your firewall settings, specifically permitting individual websites to bypass the firewall. Should all attempts prove futile, try resetting the firewall settings to default and start over.


In recap, navigating your Mac’s firewall settings doesn’t have to be nerve-wracking. By understanding your firewall and Chrome’s interaction, and performing a few simple steps, you can configure your firewall to allow Chrome to access the network.
