- For
- Mac users who want to inspect network connections
- Worth noticing
- The site reports idle measurements from an M4 Pro MacBook and notes that actual resource use varies with connection volume.
Field notes
The site describes several ways the app infers a connection’s purpose: tracker lists and host names, port conventions, destination ownership, and the connecting app. Rules can apply by app and destination, with regex hosts and “launched by” conditions; purpose-based blocking is presented as a broader control that still yields to a more specific rule. The page also links to build instructions, ownership data, and Guard documentation.
