Disable Mac OSX Firewall from Command Line

So.. you turned on the firewall on your remote Mac, and now you've locked yourself out of Screen Sharing? Good work. I've... err... never done that before.

You can turn off the firewall by setting the global state to 0:

sudo defaults write /Library/Preferences/ globalstate -int 0

Then just restart the firewall agent services:

sudo launchctl unload /System/Library/LaunchDaemons/
sudo launchctl load /System/Library/LaunchDaemons/

And presto! You're back into your Mac!
