Microsoft has announced that Windows 10 updates for older versions of Mac are ‘temporary on hold’ in a support document on their official website.

“If you are trying to update to the May 2019 Feature Update for Windows 10 (Windows 10, version 1903), you may experience an update compatibility hold and receive the message, “Mac HAL Driver – machaldriver.sys: Your PC has a driver or service that isn’t ready for this version of Windows 10.”

The company does not specify further the compatibility problem in the said document. According to the notes, Mac devices prior to 2012 or newer ones with the older Apple Boot Camp or Windows Support Software drivers cannot download or install Windows 10, v.1903.

The things the document actually specifies are the relevant versions of the file, as well as a possible solution to the issue.

“Specifically, devices with MacHALDriver.sys dated September 24, 2011 01:57:09 or older in Windows\system32\drivers are affected.

Updating your Apple Boot Camp Windows Support Software drivers may allow you to update to Windows 10, version 1903. You may be able to check for updated Windows support software, in macOS, choose Apple menu > App Store, then install all available updates. You can also try the instructions in the Apple support article here.”

Microsoft states that the company is working on a solution that will hopefully resolve the Windows 10 update problem by the end of the month.
