I am not able to kill the Geth 0.9.32 process on OS X, I forced to exit it on the Monitor Activity but it appears after 5 minutes again..
Even I restarted my computer. My last connection on Geth was yesterday with the console.
**By the way, if I start Geth by myself on the command console, on the Monitor Activities appear both of them.
I uploaded snapshots. You can see how the CPU Graph goes up.

I was using Homebrew, I uninstall the formula with this command:
https://gist.github.com/jmiehau/7a84f295bfcec39bb8e2
brew rmtree ethereum/ethereum/ethereum
'brew install ethereum` again, but I continued to have the zombie Geth.
I deleted the Homebrew formula, right now, I builded from source 9.34.1
make geth
Geth does not startup by it self unless you've done something that auto-starts if it's down.
Geth takes some time to shut down after pressing ctrl-c.
Thanks Jeff, I found from where it comes.
