I installed and started using Brickhouse, and now I wanna just go back to using the firewall in OS X, so I moved Brickhouse to the trash but System Preferences is still saying "Other firewall software is running on your computer. To change the Apple firewall settings, turn off the other firewall software." And it says "Firewall Unavailable" in the window. Is there any way I can completely remove the other firewall software and start using the internal one? Any help would be appreciated.
