steven36 Posted July 2, 2019 Share Posted July 2, 2019 Microsoft says that some Macs running Windows 10 may be blocked from updating to Windows 10 version 1903 because of a compatibility block triggered by older software or hardware. Apple Macs "introduced before 2012 or newer Mac devices with older versions Apple Boot Camp or Windows Support Software drivers installed" will not be able to install the Windows 10 May 2019 Feature Update according to a new support document published by Redmond. The Mac users who will be blocked from updating to Windows 10 version 1903 will get a "Mac HAL Driver - machaldriver.sys: Your PC has a driver or service that isn't ready for this version of Windows 10" error message. More to the point, all Macs with a MacHALDriver.sys from September 24, 2011 01:57:09 or older within the \Windows\system32\drivers folder are impacted by this issue. As the message displayed during the Windows 10 Setup says, the update will be offered to all Mac users affected by this compatibility block as soon as the issues behind the block will be resolved by Microsoft. Workarounds for Mac compatibility hold Microsoft also provides a workaround for users affected by this compatibility block, explaining that updating the Apple Boot Camp Windows Support Software drivers may allow them to install Windows 10 May 2019 Update. "You may be able to check for updated Windows support software, in macOS, choose Apple menu > App Store, then install all available updates," states Microsoft. As an alternative, users affected by the issue can also follow the detail instructions provided by Apple on this support page about installing Windows Support Software manually. Microsoft also says that a resolution for this compatibility hold is currently being under development, with a possible solution for the issue to be published during late July.
