.Hackintosh_Boardcom_Bluetooth_Fix

# Some of the hackintosh machines with Boardcom Wi-Fi/BT cards may suffer from high CPU usage after wakeup. 
# This issue is due to a daemon called "bluetoothd" that uses a lot of CPU resources. 
# These scripts attempt to resolve this issue with Sleepwatcher.

# Install
# /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
# brew install sleepwatcher
# brew install blueutil
# cp .sleep .wakeup  ~/
# chmod +x ~/.sleep ~/.wakeup

# Config and test the scripts
# /usr/local/sbin/sleepwatcher --verbose -s ~/.sleep -w ~/.wakeup

# Run sleepwatcher as a service
# brew services start sleepwatcher

.sleep

#!/bin/bash

# Output file to store connected device IDs
OUTPUT_FILE="$HOME/connected_devices.log"

# Clear previous history
> "$OUTPUT_FILE"
# Record connected device IDs
/usr/local/bin/blueutil --connected | awk '{print $2}' | sort | uniq | tr -d ',' >> "$OUTPUT_FILE"

.wakeup

#!/bin/bash

# Output file to store connected device IDs
OUTPUT_FILE="$HOME/connected_devices.log"

# Function to kill bluetoothd process and reconnect devices
kill_bluetoothd_and_reconnect() {
    # Check if bluetoothd process exists
    if pgrep -x "bluetoothd" > /dev/null; then
        # Kill bluetoothd process without typing password
        echo "password" | sudo -S kill -HUP $(pgrep bluetoothd) &> /dev/null

        # Wait before reconnecting
        sleep 1

        # Read the log file and reconnect each device
        while IFS= read -r device_id; do
