使用 mitmproxy 设置全局透明代理

brew install mitmproxy
# listen on 127.0.0.1:8080 to proxy HTTP/HTTPS traffic
sudo -u nobody mitmproxy --mode transparent --showhost

#The ports to redirect to proxy
redir_ports = "{http, https}"

#The address the transparent proxy is listening on
tproxy = "127.0.0.1 port 8080"

#The user the transparent proxy is running as
tproxy_user = "nobody"

#The users whose connection must be redirected.
#
#This cannot involve the user which runs the
#transparent proxy as that would cause an infinite loop.
#

rdr pass proto tcp from any to any port $redir_ports -> $tproxy
pass out route-to (lo0 127.0.0.1) proto tcp from any to any port $redir_ports user { != $tproxy_user }
# rdr pass on en0 inet proto tcp to any port {80, 443} -> 127.0.0.1 port 8080
