How do I know if my firewall is turned on on my Mac?
Firewall is software that protects you, so it’s best to keep it turned on. With Firewall running, your Mac takes care of everything — automatically determining whether or not an application is allowed to send or receive traffic from the network. It does this using Code Signing Certificates that are issued to trusted applications. Without the proper certification, an app isn’t allowed through. Think of it like a bouncer on the door of a club — if an app doesn’t have the proper ID it ain’t coming in. Show There may be times where Firewall isn't needed, though. For example, you’re playing a video game and don’t want to access the online multiplayer modes. Or antivirus software you’ve installed conflicts with Mac’s Firewall application. Turning off Firewall solves these problems. But you should be aware that, while switching off Firewall can stop apps on your computer from sending traffic to the network, it provides free reign for incoming connections, leaving you vulnerable to malware and other security threats. Clean your Mac before changing settingsBefore we show you how to turn Firewall on and off, it’s recommended that you have a cleanup of apps on your system, particularly those that you’ve previously deleted. If you’ve ever downloaded an app by mistake and uninstalled it or found an app to be malicious and sent it to the Trash, there’s every chance that their remnants still exist on your system. If that’s the case and you have Firewall switched off, these apps will be able to send and receive traffic, putting your Mac at serious risk. So, if you plan on playing around with the Firewall settings, use a tool like CleanMyMac X to find and remove any unwanted files stored on your Mac. CleanMyMac X scans your storage space and shows all installed apps. It also identifies broken and outdated apps so that you can easily remove them. Here’s how to use it:
