You cant even get all devices normally operating in Device manager. MacbookPro9,2 (Still and awsome hardware) in EFI mode, no way to make CIRRUS audio to Work, it simply doesnt. I guess it depends also on the model, and hardware of your mac. On my MACs installed with Windows 10 in EFI mode, always have sound issues, specially with CIRRUS hardware. I want APPLE to clarify on oficial docs about EFI and BIOS. But I need Windows on my MACs, and I paid for those licences. I dont want PCs and MACs at the same time. I cant say which Os is better than the other, but there are things I can only do on Windows, and other things I can only do with MACOS.
But also I´m a Windows fan, and I need it.
