How to Fix Wi-Fi & Bluetooth Connection Dropping on macOS (plist check via ocat)

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.
