To install the Tor service using Brew in Mac OS X:
$ brew install tor torsocks
However, this does not load the Tor service automatically (either manually or automatically at log in). Since I don’t link things to be loaded automatically for me, I’ve created the following shell script to load or unload (start or stop) the Tor service manually in Mac OS X:
#!/bin/bash
function usage() {
echo "usage: $0 start|stop";
exit 1;
}
function tor_service() {
launchctl $1 /usr/local/opt/tor/homebrew.mxcl.tor.plist
}
function start() {
echo "$0: starting tor service...";
tor_service load
}
function stop() {
echo "$0: stopping tor service...";
tor_service unload
}
function check() {
echo "$0: checking if tor works...";
if torsocks curl -s https://check.torproject.org | grep -q 'Congratulations. This browser is configured to use Tor.'; then
echo 'The tor service works';
else
echo 'The tor service does NOT work';
fi
}
case "$1" in
help|--help|-h)
usage;;

*)
echo "error: missing or unrecognized command-line argument";
usage;;

To start (load) the Tor service:
./tor.sh start
To stop (unload) the Tor service:
./tor.sh start
To check whether the Tor service is working:
./tor.sh check
To tor-ify command-line tools like curl or wget:
torsocks wget https://check.torproject.org/
