MP 1,1-5,1 OCLP 2.2.0 MacPro 5,1: WiFi but no Bluetooth on Sequoia

[Vademecum]

Greetings!

I'm running Monterey 12.7.6 with OCLP 2.2.0 on the MacPro 5,1 (2010) on a SATA SSD

The Bluetooth-WiFi is the stock card, the BRCM2046

This Mac Pro also has a PCI 3.0 card:

On Monterey, both WiFi and Bluetooth work once applied the Root Patches (the Bluetooth chipset is then detected as "THIRD_PARTY_DONGLE"). Also, on a separate SSD in which I have unpatched Mojave: natively, it works and is recognized as the Broadcom 2046. Additionally, Bluetooth also works on a separate Windows 10 hard disk (MBR).

However, I did a clean installation of Sequoia 15.3 on a new volume (not partition) of the same SSD which has Monterey and while the WiFi works, the Bluetooth doesn't.
I thought that maybe the OpenCore for Monterey could interfere with the one for Sequoia since the required patches could be different. Hence, I did a clean install of Sequoia 15.3 on a separate hard disk (Not SSD). Still, same results: WiFi is working but Bluetooth isn't.

Things I tried without success:
- Re-built and Re-installed OpenCore (several times)
- Re-patched the Root Patches, including the Legacy Wireless (several times)
- Deep PRAM (4 times) and SMC reset
- Removed the Monterey SSD in case the OC boot would interfere with the one installed on the Sequoia Hard Disk (not sure if this is possible, but just in case)
- With OpenCore Configurator, I confirmed that both Bluetooth kexts are enabled. Also, I disabled them and re-enabled them just in case, without success.

A couple of years ago, I tried Ventura but I had the same issue, so I sticked with Monterey.
I read posts of people mentioning the stock WiFi and Bluetooth are working even on Sequoia but I don't know what I am missing here.
Any help would be appreciated

Hi there, having the same issue.
I'm on Sonoma 14.7.3 wifi and bluetooth working well. Mac Pro 5.1 mid 2010 updated wifi-usb card.
Went the same route as you, HHD drive erased well (7step) and installed Sequoia 15.3 fresh.
No Bluetooth, switching off and on again the bluetooth-spoof and fixup kext. Not together tough.
Did the whole shebang like you did PRAM and so on but such luck!

I have WiFi and BT on Sequoia 15.2 on my cMP 5,1 2x3,46GHz.

... but like you, I have no BT after a fresh install of 15.3.1 on a cMP 5,1 mono 3,46GHz.

I'm afraid that it's the fresh install that's screwing things up. Thus, we should update to 15.3.1 from 15.2 via Software Update ?

I think I ill try to install Monterey with OCLP on cMP 5,1 mono 3,46 GHz to be sure to have BT and WiFi, then I will do an upgrade to Sequoia an cross my fingers !

Here are the screenshots of my cMP 5,1(2010) 2x3,46 GHz with a WiFi ac BT 4.2 BCM943602CDP upgraded module, with working BT and WiFi, running Sequoia 15.2 :

In the forthcoming days, I will try to modify the config.plist of my cMP 5,1 (2010) mono-3,46 GHz to see if that fixes the BT issue.

I managed to install Sonoma 14.7.2 with working Bluetooth and working WiFi.

Here is how I did :

1. Install OCLP 1.5.0 in EFI Boot and reboot.
2. Boot on an external "Installer macOS Monterey 12.7.6" volume to do a fresh install of macOS Monterey.
3. Proceed to the full install of Monterey.
4. Once in Monterey, run OCLP 1.5.0 and apply "Root Patches" and reboot into Monterey 12.7.6: Bluetooth and WiFi are directly working !👍🏻
5. Boot on an external "Installer macOS Sonoma 14.7.2" volume and install macOS Sonoma over the macOS Monterey.
6. Proceed to the full install of macOS Sonoma.
7. Once in Sonoma, run OCLP 1.5.0 and apply "Root Patches" and reboot into Sonoma 14.7.2 : Bluetooth and WiFi are directly working !👍🏻
8. Install OCLP 2.2.0 in EFI Boot and reboot.

⚠️ Do not install Sonoma 14.7.4 (neither via System updates nor full installer), because it will disable the Bluetooth (WiFi will be ok unmodified).
