    I am trying to install on a 2013 Mac Pro 6,1. I am running Sonoma on OpenCore patcher. The Windows installation goes fine up to a certain point. I am able to install Windows (Win11_25H2_English_x64_v2) without a problem. I can boot into Windows 11 without a problem. I can go anywhere in Windows without a problem until I install the "Windows Support" drivers (downloaded using Bootcamp on the Mac Pro). As soon as this has been loaded, the computer develops a Kernel error (Stop code: KERNEL SECURITY CHECK FAILURE (D139)) and reboots.
    I have deleted NTFS programs from the Mac (as seen in a different thread).
    I have redownloaded and installed Windows Support drivers multiple times
    I have run Windows repair without effect.

    Hello. It looks like the problem is related to the drivers.
    Maybe this will help? You can ask your question there.

      That's the video I used! I'll ask.

    You can also install drivers one by one instead of a package to identify the culprit.

      I am not sure how to do that, but I'll see what I can do.
