First, download and install chromium (because running a browser with SSL verification turned off is insecure -- only use this browser for accessing mesos).

open -a /Applications/Chromium.app \
    --args \
    --proxy-server=socks5://127.0.0.1:9999 \
    --host-resolver-rules="MAP * 0.0.0.0 , EXCLUDE 127.0.0.1" \
