I’m on Mac Sierra. I’m trying to start my Tor instance, but evidently it is already running on my computer …

localhost:myproject davea$ tor --CookieAuthentication 0 --HashedControlPassword "" --ControlPort 9050 --SocksPort 50001

I tired to figure out what the PID is of the process running on the specified ports, but Mac tells me nothing …

localhost:myproject davea$ 
localhost:myproject davea$ 
localhost:myproject davea$ lsof -i :9050
localhost:myproject davea$ 
localhost:myproject davea$ lsof -i :50001
localhost:myproject davea$ netstat -anp tcp | grep 50001
localhost:myproject davea$ netstat -anp tcp | grep 9050
localhost:myproject davea$ 
localhost:myproject davea$

Any ideas how I can figure out what the PID is and kill it so I can start up Tor?

To find out which PID is using a particular port:

$ lsof -t -i :9050

The commands you've indicated are correct, so you might want to confirm whether or not lsof and netstat are actually working by doing a more generic command as a test, for example:

$ lsof -i

If that still doesn't return anything then you'll know the problem not isolated. Depending on your users permissions you might need to execute lsof or netstat with sudo:

$ sudo lsof -i -P

There's also the possibility neither returns anything because the port might not actually be open:

Confirm whether or not a torprocess is actually running per the notice:

$ ps ax | grep tor
