Disable Bluetooth permanently
I found a gist that removes the launchds & the kernel extensions for the bluetooth. It will make the system incapable of using the bluetooth features :
#!/bin/bash
# disable bluetooth
# OS X 10.8.2
# 2012-10-08
home=$HOME
bk=$home/backup-bluetooth-extentions
mkdir $bk
# sudo reboot with Shift Key # Safty Boot
# Login as Admin usert.
#---------------------------------------------------------------------
# Local Backup OFF
#---------------------------------------------------------------------
# sudo tmutil disable
# sudo tmutil disablelocal
#---------------------------------------------------------------------
# Agnet
#---------------------------------------------------------------------
# bluetooth
launchctl unload -w /System/Library/LaunchAgents/com.apple.bluetoothUIServer.plist
launchctl unload -w /System/Library/LaunchAgents/com.apple.bluetoothAudioAgent.plist
#---------------------------------------------------------------------
# Daemon
#---------------------------------------------------------------------
sudo launchctl unload -w /System/Library/LaunchDaemons/com.apple.blued.plist
sudo launchctl unload -w /System/Library/LaunchDaemons/com.apple.bnepd.plist
sudo launchctl unload -w /System/Library/LaunchDaemons/com.apple.IOBluetoothUSBDFU.plist
#---------------------------------------------------------------------
# Extentions

sudo mv /System/Library/Extensions/AppleHIDKeyboard.kext/Contents/PlugIns/AppleBluetoothHIDKeyboard.kext $bk
sudo mv /System/Library/Extensions/AppleHIDMouse.kext/Contents/PlugIns/AppleBluetoothHIDMouse.kext $bk

sudo touch /System/Library/Extensions
echo 'Shut Down & Restart'
