Turning off Firewall solves these problems. Or antivirus software that you’ve installed is conflicting with Mac’s Firewall application.
Say, for example, you’re playing a video game and don’t want to access the online multiplayer modes. There may be times where Firewall isn't needed, though. 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. Without the proper certification, an app isn’t allowed through. It does this using Code Signing Certificates that are issued to trusted applications. 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.
