Macintosh computers running OS X come equipped with built-in firewalls designed to protect against potentially harmful or malicious inbound connections. The primary function of the firewall is to prevent or restrict access to your computer from other computers and the Internet. In certain situations, your Mac firewall might clash with the firewalls in third-party hardware you use, necessitating you to either completely disable the Mac firewall or adjust its settings. Keep reading to discover how to turn off or deactivate the firewall integrated into your Mac.
