Qualquer visão sobre isso seria muito útil para mim. Estou usando um Mac Mini 2011. Corri ifconfigpara ver as interfaces de rede e vi três placas Ethernet. Alguns estão em modo promíscuo, embora apenas um tenha IP e esteja ativo. No entanto, é normal ver três interfaces Ethernet e por que isso aconteceria, já que existe apenas uma interface Ethernet?
Aqui está a saída do ifconfig:
en0: flags=8963<UP,BROADCAST,SMART,RUNNING,PROMISC,SIMPLEX,MULTICAST> mtu 1500

Isso é normal para um Mac? Por exemplo, executo ifconfig em uma máquina Linux Debian e obtenho:
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500

Isto é normal. O macOS usa enXinterfaces de rede Ethernet, Ethernet sem fio (802.11/Wi-Fi) e Thunderbolt.
No seu Mac mini 2011, en0há Ethernet integrada, en1Wi-Fi e en2Thunderbolt.
