Application Firewall is disabled by default.ДЄfter enabling the Application Firewall ( System Preferences -> Security & Privacy -> Firewall -> Turn On Firewall), youвЂ™ll find PF is enabled too: $ sudo pfctl -s info OS X v10.5.1 and later include Application Firewall that allow the users to control connections on a per-application basis (rather than a per-port basis).

Status: Disabled Debug: Urgent Application Firewall PF is disabled by default: $ sudo pfctl -s info The launchd configuration file for PF is /System/Library/LaunchDaemons/. The main ruleset loads sub rulesets defined in /etc/pf.anchors/com.apple, using anchor: anchor '200.AirDrop/*' anchor '250.ApplicationFirewall/*' The main PF configuration file is /etc/pf.conf, which defines the following main ruleset by default in OS X 10.9 & 10.10: scrub- anchor 'com.apple/*' nat- anchor 'com.apple/*' rdr- anchor 'com.apple/*' dummynet- anchor 'com.apple/*' anchor 'com.apple/*' load anchor 'com.apple' from '/etc/pf.anchors/com.apple' s References Show pf- enable reference statistics ( pid/ name of enabler, token, timestamp). X token Release the pf enable reference represented by the token passed. HereвЂ™s how they are documented in pfctl(8): - E Enable the packet filter and increment the pf enable reference count. These two flags, -E and -X, are absent from pfctl on other BSDs. # is disabled only when the last enable reference is released. # PF via -E and -X as documented in pfctl(8). # each component which utilizes PF is responsible for enabling and disabling PF will not be automatically enabled, however. The latest OpenBSD version is 5.6 (as of January 2015) and the configuration syntax for PF changed around 4.6/4.7.ДЄpple has enhanced PF so that various system components might choose to enable and disable PF, as indicated by the following snippet in /etc/pf.conf: # This file contains the main ruleset, which gets automatically loaded Like FreeBSD 9.X and later, OS X appears to use the same version of PF as OpenBSD 4.5.

PF in OS X, however, appears to be based on the FreeBSD port of PF. PF (Packet Filter) is OpenBSDвЂ™s system for filtering TCP/IP traffic and doing Network Address Translation. IPFW was deprecated in OS X 10.7, and was completely removed in OS X 10.10 it was replaced with PF.

Mac OS X 10.6 (and earlier) came with IPFW, a port of FreeBSDвЂ™s stateful firewall. Starting from version 10.7 (Lion), Mac OS X includes 2 firewalls: PF & Application Firewall.
