If you are installing or upgrading Windows 10 on Mac machine using Apple Boot camp assistant software and getting “Mac HAL Driver – machaldriver.sys error, Your PC has a driver or service that isn’t ready for this version of Windows 10” then you are at right place. If you face this error then your Mac machine is older (manufactured prior 2012) or you might be running an older version of Windows support software or Apple boot camp assistant.

The latest version of Windows 10 May update 2019 does not support the older Mac devices which are manufactured prior to 2012. Windows\system32\drivers folder shows the error (Mac HAL Driver – machaldriver.sys error) because Mac with MacHALDriver.sys date is September 24, 2011, or older.
