Disable Bluetooth permanently How do you permanently disable Bluetooth on OS X Mavericks?  It seems that simply shutting it off in preferences doesn't disable it.
I found a gist that removes the launchds &amp; 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
