Problem: the latest Windows 10 update 1903 runs into BSOD (Blue screen of death) with error message WDF_VIOLATION on some mac models (MacBook Pro 2010/2011, MacBook Air 2011, Mac Mini 2012, iMac 2010/2011 and some others). This fatal failure occurs when Windows is already loaded and system tries to start Apple Boot Camp Utility (BootCamp.exe). This tool is responsible for controlling screen brightness, volume, functional keys, backlit, etc with Apple keyboard. On some machines crash happens only if you try to start our Macs Fan Control app.

Windows 10 should also work with this setup. The difference in GPUs (GT650m - MacBook Pro (Retina, 15-inch, Mid 2012) - Technical Specifications vs GT750m - MacBook Pro (Retina, 15-inch, Late 2013) - Technical Specifications ) should not be causing such behavior. Boot Camp Windows 10 not booting – If the Boot Camp Windows partition no longer boots, try to perform the NVRAM reset to clear all corrupted settings. Boot Camp won’t install Windows 10/Bootcamp installation failed – There are times when Boot Camp refuses to install on Windows 10. In this case, waste no more time and download the latest. Cause: older versions of the MacHALDriver.sys driver supplied with the Boot Camp Utility are not compatible with Windows 10 1903. Solution: Basically you need to update to Boot Camp 6 or later. First you need to disable the old driver to allow Windows to boot normally.

Cause: older versions of the MacHALDriver.sys driver supplied with the Boot Camp Utility are not compatible with Windows 10 1903.

Solution: Basically you need to update to Boot Camp 6 or later.

First you need to disable the old driver to allow Windows to boot normally. The driver file located at c:windowssystem32MacHALDriver.sys must be renamed, e.g. to “MacHALDriver.sys.old”. There’re 2 options here:

• (from Windows) Boot up in safe mode (holding the F8 key) and rename the file.
• (from macOS) Install Tuxera NTFS or Paragon NTFS for Mac to allow write access to Windows drive/partition and rename the driver file. Both apps are commercial but have a trial period.

Bootcamp Updates Windows 10

After that you can boot Windows 10, but Apple Boot Camp Utility won’t work. Macs Fan Control is able to work without the Boot Camp driver but slowly.

Install 7Zip and Brigadier. Run the latter to download and install the latest official Boot Camp from Apple for your machine. Sometimes it may still download a faulty old version (e.g. for mid-2010 iMac), in this case we recommend downloading Boot Camp for another model using the –model parameter:

and run the Boot Camp installer manually (run your command prompt as administrator):

Tip: to avoid this problem, we highly recommend updating your Boot Camp using the Brigadier app before updating Windows to 1903.
