GUIDE How to Fix Bluetooth on macOS Monterey and Later

The firmware reports

Firmware Version: v0 c0

This indicates the firmware is not loading. First, the kext is not in sorted order.

Try under Ventura first. Also, add -btlfxallowanyaddr as boot arg and then check.

What is correct kext order?

What is correct kext order?

Mandatory kexts should load first. Lilu, VSMC, WEG, etc. For WiFi, it should be, AirportBrcmFixup, BrcmFirmwareData.kext, BrcmPatchRAM3.kext, BlueToolFixup.kext

Reordering kexts helped - on Ventura (see attachment). On Sequoia, however - there is PXSX process stalling, and bluetooth section is frozen in system information.

Managed to fix that by cleaning logs, but bluetooth works only if I boot into ventura and then into sequoia. Guess I will stick to ventura til I get a better wifi card or a real macbook

That's only important for the WiFi, not the BT. The BT should work without those as its on USB bus.
