Well known TCP and UDP ports used by Apple software products

Well known TCP and UDP ports used by Apple software products (Apple KnowledgeBase) [Link via @x0prahWinfr3yx]

Excellent, though not necessarily comprehensive list of network ports used by Apple services. Apple states on this page that the list is periodically updated but is not intended to be representative of all network ports used by all Apple services/applications.

Still, it's a great place to start if you're looking for network security information regarding Apple products. Follow that up with some judicious use of Wireshark and you're in business.

And, just for good measure since we're talking about securing Apple (Mac OS X 10.5 and 10.6) devices, this is a good companion article:  About the Application Firewall


  1. Excellent find! The Mac documentation on About the Application Firewall was really helpful too, thanks!

  2. Can't take credit for the find, as noted above, but glad you found it useful.
