A solução está na ferramenta de linha de comando menos conhecida airport .
Qual é encontrado em /usr/sbin
antes do Snow Leopard (e, portanto, pode já estar no seu PATH),
Para um sistema operacional mais recente, ele pode ser encontrado em /System/Library/PrivateFrameworks/Apple80211.framework/Versions/Current/Resources
Nesse caso, o comando que você deseja emitir é o seguinte:
sudo airport en1 prefs RequireAdmin=YES
A página do manual está praticamente vazia e a emissão do aeroporto --help realmente fornece menos informações de uso do que a emissão do comando sem nenhum argumento. Este último dá a seguinte explicação:
Usage: airport <interface> <verb> <options> <interface> If an interface is not specified, airport will use the first AirPort interface on the system. <verb is one of the following: prefs If specified with no key value pairs, displays a subset of AirPort preferences for the specified interface.
