**Note**: Due to macOS PF (Packet Filter) limitations, httpjail uses environment-based proxy configuration on macOS. PF translation rules (such as `rdr` and `route-to`) cannot match on user or group, making transparent traffic interception impossible. As a result, httpjail operates in "weak mode" on macOS, relying on applications to respect the `HTTP_PROXY` and `HTTPS_PROXY` environment variables. Most command-line tools and modern applications respect these settings, but some may bypass them.
