Hackintosh with MSI Z370 A Pro Motherboard BT Problem

Q: What is a Hackintosh?

A non-Apple computer configured to run macOS using compatible PC hardware combined with a custom bootloader and configuration files to emulate a real Mac environment.

Q: Is building a Hackintosh legal?

Installing macOS on non-Apple hardware violates Apple’s End User License Agreement (EULA). It is generally not illegal for personal experimentation but not permitted for commercial use.

Q: What hardware is best for a Hackintosh?

The best hardware closely matches real Apple systems, with Intel CPUs (6th Gen to Core Ultra), AMD Radeon GPUs, compatible chipsets, and Intel-based Wi-Fi cards offering higher success rates.

Q: Can I build a Hackintosh with an AMD CPU?

Yes, macOS can run on AMD Ryzen CPUs using kernel patches, but Intel CPUs provide better native compatibility.

Q: What is OpenCore?

OpenCore is a modern Hackintosh bootloader that provides near-native macOS behavior and is the recommended bootloader for new installations.

Q: Is Clover still supported?

Yes, Clover is still supported but less recommended compared to OpenCore for modern systems.

Q: Which macOS versions support Hackintosh?

Hackintosh systems support macOS versions from Leopard up to recent releases, depending on hardware compatibility.

Q: Do NVIDIA graphics cards work on Hackintosh?

Only older NVIDIA GPUs work on older macOS versions; modern NVIDIA GPUs are incompatible with current macOS releases due to lack of driver support.

Q: What is an EFI folder?

The EFI folder contains the bootloader, drivers, kexts, and configuration files required to boot macOS on a Hackintosh.

Q: What are kexts?

Kexts (kernel extensions) are drivers that enable hardware functionality such as audio, Ethernet, USB, and graphics.

This issue specifically concerns macOS Sequoia 15.7.4

The problem is that neither SMBIOS MacPro7,1 nor SMBIOS iMac 19,1 allows a BT4.0 USB Bluetooth adapter to work.

A UART BT device (ghost device) is always displayed, which doesn't actually exist, see here from the system report - Bluetooth:

Bluetooth Controller:

Address: NULL

Status: Off

Chipset: BCM_4350C2

Visible: Off

Firmware Version: v0 c0

Supported Services: 0x392039 < HFP AVRCP A2DP HID Braille LEA AACP GATT SerialPort >

Transport: UART
Vendor ID: 0x004C (Apple)

I checked ChatGPT, but it only gives nonsense.

Does anyone here perhaps have the same motherboard and use Bluetooth?

I'm grateful for any help.

My Bluetooth USB dongle is a:

BCM920702 Bluetooth 4.0:

Product ID: 0x21e8
Manufacturer ID: 0x0a5c (Broadcom Corp.)
Version: 1.12
Serial Number: 5CF3706681C8
Speed: Up to 12 Mbps
Manufacturer: Broadcom Corp.
Site ID: 0x14500000 / 2
Available Current (mA): 500
Additional Operating Current (mA): 0
Integrated: Yes

It is also correctly mapped internally to USB port HS09 using Hackintool, with port 255.
