IntelBluetoothFirmware.kext does not load on macOS Ventura

[rndmtk]

Have you read the docs?

Yes

macOS Version

macOS 13.7.6

Kext Version

v2.4.0

Wireless Adapter Model and USB Product ID

Intel Centrino Wireless-N 2230 BGN (0x07DA)

Description

For whatever the reason is, despite being Enabled in the OpenCore config.plist, the IntelBluetoothFirmware.kext does not load at all. I have been rebooting and resetting the NVRAM multiple times, even went as far as reverting the OCLP root patches (for Intel Graphics and Atheros Wi-Fi), but still nothing. BlueToolFixup and IntelBTPatcher load just fine however.

Even tried multiple loading orders, made no difference.

Also, the Bluetooth HCI USB device does show up after mapping, but still no results.

Side note: Since the Wi-Fi slot in my laptop lacks the USB lines necessary for Bluetooth, I installed the Intel Wireless card in the cellular modem (WWAN) slot. Bluetooth works just fine when using Windows/Linux. For Wi-Fi I use an Atheros card.

Quick update: Setting the following NVRAM variables from BrcmPatchRAM has gotten my Bluetooth working.

• 7C436110-AB2A-4BBB-A880-FE41995C9F82:bluetoothExternalDongleFailed — 00
• 7C436110-AB2A-4BBB-A880-FE41995C9F82:bluetoothInternalControllerInfo — 0000000000000000000000000000

Although the IntelBluetoothFirmware.kext still won't load.

I've been facing the same issue since last night, on Sequoia and Sonoma. According to Hackintool,

• BlueToolFixup.kext does not load
• IntelBluetoothFirmware.kext loads, without IntelBTPatcher.kext.

Bluetooth is recognized in System Report,

as well as under USB:

I've tried the following fixes to no avail:

• Mapped my USB Ports on Windows.
• Grabbed the latest Release Kexts.
• Used bluetoothInternalControllerInfo and bluetoothExternalDongleFailed in NVRAM.
• Used -btlfxboardid and -btlfxallowanyaddr.
• Checked my BIOS repeatedly.

Bluetooth works fine on Windows, but on macOS it often doesn't work, and some of the issues as of now are:

• BT4 (BLE) Device connectivity.
• Proper documentation for the patches required with BrcmPatchRAM kexts.

If anyone has worked out a fix to these issues, I'd be super grateful for the support.
