How to Fix Open Core Legacy Patcher on macOS

Wi-Fi, Bluetooth, AWDL, Continuity and Location Services problems usually come from chipset support, kext pairing, privacy settings or network-location corruption. On Hackintosh systems, Location Services and Continuity depend on working Wi-Fi, Bluetooth, AWDL and correct AirportItlwm or itlwm/HeliPort behaviour.

Quick Checks

  • Backup current state: Save a copy of your working EFI and run a full system backup before changing settings.
  • Identify hardware components: Note down your exact CPU, GPU, Wi-Fi card, and motherboard/laptop model.
  • Ensure utility alignment: Keep OpenCore, OCLP, and ProperTree updated.

Fix Steps

  1. Create a rollback point: Make a Time Machine backup and keep a copy of your last working EFI folder before editing OpenCore, kexts or root patches.
  2. Confirm the exact chipset: Identify the Wi-Fi, Bluetooth and Ethernet controller from System Information, Hackintool or Linux/Windows device manager.
  3. Use the correct network stack: Match AirportItlwm, itlwm, HeliPort, IntelBluetoothFirmware and BlueToolFixup to the exact macOS version.
  4. Reset macOS network state: Remove the current Wi-Fi service, reboot, add it again, then reconnect to a simple WPA2 network before testing advanced features.
  5. Check privacy permissions: Open System Settings and confirm Location Services, Maps, Weather and system services are enabled.
  6. Test Apple features separately: Verify normal internet first, then Bluetooth, then AirDrop/Continuity. Do not debug all three at the same time.

Do Not Continue If

  • Do not continue if: you do not have a working EFI backup, a Time Machine backup, or another bootable macOS installer.
  • Stop and capture evidence: if the machine stops booting, take a photo of the last verbose line before changing more settings.

Verify It Worked

  • Maps can locate you without falling back to a stale location.
  • Wi-Fi reconnects after reboot and sleep.
  • Bluetooth remains available after a cold boot.
  • Console no longer shows repeated wireless or location daemon errors.

Rollback

  • Restore the previous EFI if Wi-Fi disappears completely.
  • Switch from AirportItlwm to itlwm + HeliPort, or the reverse, if the issue is specific to one driver path.
  • Use Ethernet or USB tethering while testing so you do not lose access to downloads.

Next Action

  • Test now: reboot twice, reproduce the original problem, and confirm whether the same symptom returns.
  • If it still fails: record the Mac model, macOS build, OpenCore or OCLP version, GPU, Wi-Fi/Bluetooth chipset, and the last visible error.
  • Read next: use the related searches below for the nearest OpenCore or OCLP fix before making another change.

Original Question: "Open Core Legacy Patcher..."

What I have: macOS Monterey 12.7.4

iMac (27-inch, Mid 2011)

Memory 16GB 1333 MHz DDR3

Processor 3.4 Ghz Quad-Core Intel Core i7

Graphics AMD Radeon HD 6970M 2048MB

I say this because last week I was splendedly running Sonoma with no issues then I hit the update button that OCLP pushes when booting up. Oops. Lost total setup and can't get back. I've tried and tried and tried with no success. So now I am running Monterey and here's what I've discovered. The Post Install Patches DON'T work! When I used them I lost Apple Menu, Tool Bar, Keyboard (wired) and all internet (WiFi and Ethernet) . Thank goodness there was a revert patches button because that solved everything. This is my experience for today. I would love to get Sonoma back but I just can't figure out how to get there. Yes, I've viewed the Youtube videos and have tried them as posted. They don't work for me.
