Can't Boot Windows After Activating spoof_osx

[Justin Cooke]

I have refind 0.10.5 successfully installed, dual-booting OS X 10.12.3 and Windows 10. When I turn on spoof_osx Windows will no longer boot - hangs on the startup screen and either freezes or restarts. Disable it again, and Windows boots fine.

I've tried varying the version number, 10.9, 10.12, 10.12.3, with no success.

I'm using this to attempt to use the integrated graphics on my 2015 Macbook Pro in Windows rather than the discrete Radeon GPU.

Thoughts? Suggestions?

I suggest posting on Mac and Windows forums about this. The rEFInd spoof_osx_version feature is very simple, so if it's not working, it's unlikely you'd be able to tweak it beyond things you've already tried. You might find a solution within Windows, though. Fundamentally, the problem you're encountering is likely caused by a mis-match of the Windows video drivers' assumptions and the way the hardware is configured at boot time. Thus, a change to the video drivers (their settings or a change in the driver version itself) may fix the problem.
