Fix Machaldriver.sys errors
Several errors had been spotted related with Machaldriver.sys. They usually occur when there is an incompatibility between the Apple Driver and Windows Driver. In this post, we will offer solutions that you can use to fix those errors.
1] Your PC has a driver or service that isn’t ready for this version of Windows
The full error message goes as:
Mac HAL Driver – machaldriver.sys: Your PC has a driver or service that isn’t ready for this version of Windows. No Action is needed. Windows Update will offer this version of Windows automatically once the issues have been resolved.
The error occurs in one of the scenarios:
- Macbook which was manufactured before 2012.
- You are running an older version of Windows or Apple Boot Camp.
In both cases, you must update Windows and BootCamp drivers to resolve the problem.
2] WDF_Violation Blue Screen Error
The WDF_Violation error occurs as the MacHALDriver.sys cause Bootcamp.exe to crash. It occurs after entering credentials.
To temporarily resolve the issue, you must rename the MacHALDriver.sys (available in the C:\Windows\system32\drivers folder) to MacHALDriver.bak.
To do so, boot into Safe Mode, and change the file name. However, once you reboot, you may lose some of the Macbook features, and the Fn keys will stop working.
The baseline is that if there is an issue, it is mostly the driver and compatibility issue. You will have to wait for an update to arrive, and only then can it be resolved.
