Hackintosh Bluetooth Reset Fix

com.bluetooth.reset.plist

<?xml version="1.0" encoding="UTF-8"?>
<!-- 
On an OpenCore Hackintosh running macOS 15 Sequoia, the NVRAM setting 'bluetoothExternalDongleFailed', 
used as part of the Broadcom bluetooth fix, keeps getting reset to '01', which disables bluetooth. 

I wrote the following script to address this.

It can be placed in '/Library/LaunchDaemons/' with permissions set using 'sudo chmod 644 com.bluetooth.reset.plist'. 
The script will then run on startup to reset the NVRAM value back to '00'.
