AppleBluetoothBroadcom64 is not properly signed

The bootcamp ( 6.1.7438 ) driver for Apple made bluetooth cards is not properly signed and therefore cannot be used unless booted with disabled signature checks. It seems to be signed with some development certificate:

Without deactivating the checks this is what you see when you try to install the driver:

After disabling the checks by using advanced startup options the install is possible. You see a warning but it will install and operate the device flawlessly:

The device in question: VID = 05AC (Apple) PID = 828F

I guess Apple just needs to not forget to properly sign the driver when they update the Bootcamp software. I have no idea what might be the best way to contact the about that. The Feedback Bug reporter does have no category that fits.

Use 'macOS' -> (Something Else Not on This List, Suggestion) category and be very specific with your report and specifically mention Bootcamp Drivers, not Bootcamp Assistant.

You can also use Brigadier to download an older BC driver package, if available for your specific model.

I did file the bug with Apple. In the meantime I downloaded an older driver version with Brigadier as you suggested which works! However, I did not understand how to explicitly download older versions. There was only a --model command line option. I figured to just supply an old MacBook model and hope for the best:

brigadier.exe --model MacBookPro11,1

There is a "-p" qualifier.

./brigadier -h
Usage: brigadier [options]

Options:
  -h, --help            show this help message and exit
  -m MODEL, --model=MODEL
                        System model identifier to use (otherwise this
                        machine's model is used). This can be specified
                        multiple times to download multiple models in a single
                        run.
  -i, --install         After the installer is downloaded, perform the install
                        automatically. Can be used on Windows only.
  -o OUTPUT_DIR, --output-dir=OUTPUT_DIR
                        Base path where the installer files will be extracted
                        into a folder named after the product, ie.
                        'BootCamp-041-1234'. Uses the current directory if
                        this option is omitted.
  -k, --keep-files      Keep the files that were downloaded/extracted. Useful
                        only with the '--install' option on Windows.
  -p PRODUCT_ID, --product-id=PRODUCT_ID
                        Specify an exact product ID to download (ie.
                        '031-0787'), currently useful only for cases where a
                        model has multiple BootCamp ESDs available and is not
                        downloading the desired version according to the post
                        date.
