How to Fix Wi-Fi & Bluetooth Connection Dropping on macOS (The final hurrah of my hackintosh (11 years!))

Wireless connection drops, missing Bluetooth Low Energy (BLE), or unrecognised cards stem from kext version mismatches between AirportItlwm, BlueToolFixup, and Intel/Broadcom firmware. Matching driver sets fixes AirDrop, Handoff, and peripheral stability.

Step-by-Step Resolution Guide

1. Match Driver to macOS Release: Always use the matching AirportItlwm version built for your exact macOS release (Sequoia, Sonoma, Ventura, Tahoe).
2. Configure Bluetooth Stack correctly: On macOS Monterey and newer, use BlueToolFixup.kext alongside IntelBluetoothFirmware.kext.
3. Reset Network Preferences: Delete corrupted network plist files from /Library/Preferences/SystemConfiguration/ and reboot.
4. Disable Conflicting Kexts: Ensure legacy kexts like BrcmBluetoothInjector are disabled on macOS Monterey and later.

Copyable Network Reset & Diagnostic Commands

1. Terminal Commands to Reset macOS Network Configuration:

sudo rm -f /Library/Preferences/SystemConfiguration/NetworkInterfaces.plist
sudo rm -f /Library/Preferences/SystemConfiguration/preferences.plist
sudo killall -HUP mDNSResponder

2. Check Active Wireless & Bluetooth Drivers:

kextstat | grep -E "itlwm|BlueTool|IntelBluetooth"

Verification Checklist

• The system boots consistently without unexpected verbose halts.
• Target hardware components (Graphics, Audio, Wi-Fi/Bluetooth, NVMe) display correctly in System Information.
• No kernel panic logs appear during sleep, wake, or full reboot.
• A clean backup of the functional EFI directory is saved on external storage.

Rollback Protocol

• Boot from your secondary emergency FAT32 USB containing the original working EFI.
• Reset NVRAM from the OpenCore picker to flush temporary boot argument modifications.
• Restore system state using Time Machine if core macOS system binaries were modified.
