Firewall is software that’s there to protect 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.
There may be times where Firewall isn't needed, though. Say, for example, you’re playing a video game and don’t want to access the online multiplayer modes. Or antivirus software that you’ve installed is conflicting 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 hackers.
Clean your Mac before changing settings

Before 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.

Here’s how to use it:
- Download and launch CleanMyMac X. (Free download)

- Click on View All Applications and select any apps that you wish to remove from the list. Apps can be sorted by Name, Size, Selection, and Last Launch Date to help your search.

- Click on the Uninstall button and enter your admin password when prompted.
Selected apps will now be completely removed from your system.
