How to Fix Wi-Fi issue on MBP Late 2013 running macOS Sequoia via OCLP (kWiFiLocWPASecurity errors) on macOS
Network issues normally come from the wrong kexts, stale root patches, USB mapping, or unsupported wireless hardware.
Step-by-Step Fix:
- Back up first: Make a Time Machine backup or clone before changing OpenCore, EFI, root patches, or macOS versions.
- Confirm the chipset: Identify the exact Wi-Fi/Bluetooth or Ethernet controller, not only the laptop model.
- Use matched kexts: Pair Intel Wi-Fi with AirportItlwm or itlwm for the exact macOS version; pair Bluetooth with IntelBluetoothFirmware and BlueToolFixup when required.
- Rebuild and reset: Update OpenCore, clean NVRAM, rebuild the config snapshot and reboot.
- Test a simple network: Try WPA2 personal hotspot, Ethernet or USB tethering to separate router security problems from driver problems.
Final check: Change one thing at a time, reboot, and keep a copy of the last working EFI before the next test.
Original Question: "Wi-Fi issue on MBP Late 2013 running macOS Sequoia via OCLP (kWiFiLocWPASecurity errors)"
Hi everyone,
I'm having a weird Wi-Fi issue with my MacBook Pro Retina (15-inch, Late 2013, Intel Iris Pro, 8GB RAM). It is currently running macOS Sequoia 15.7.8 via OCLP.
The Wi-Fi works perfectly fine when tethering to my iPhone's personal hotspot (WPA2). However, it completely refuses to connect to my home Wi-Fi network.
When trying to connect to home Wi-Fi, it opens Wireless Diagnostics and shows these localization bug errors in the menu bar:kWiFiLocWPASecurityTitle,kWiFiLocWPASecurityDescription, andkWiFiLocWPASecurityRecommendation.
I have already tried:The iPhone connection still works, but home Wi-Fi does not. Any ideas on how to fix this router/kext conflict? Thanks!
