I've been trying to install Windows 10 on an early 2011 Macbook Pro. It's not officially supported, but I read everywhere it can be done. There are some troubles though.

I have successfully installed it alongside MacOS High Sierra actually, and everything works fine except for audio. I get the exclamation point on Device Manager and a message saying the device couldn't be started properly.

I found out audio doesn't work because Uefi Windows 10 installation somehow keeps a Cirrus audio-related device from working. At least that's what I understood after googling myself to death.

So I tried to install Windows 10 in Legacy/Bios mode. I chose "Windows" for the setup DVD instead of "Uefi Boot" at boot.

But just before the point where Windows usually asks which disk to install on, it actually asks for a missing driver. This doesn't happen when installing in Uefi mode. I tried feeding it Intel xHCI drivers with usb keys, it sees the keys but says it doesn't find any driver.

So I was wondering, is this behavior due to the fact the disk is partitioned in Uefi mode? So is it impossible to install Windows 10 in Bios mode in such a setup, or am I instead missing something?

NOTE: I wasn't able to use Boot Camp and had to prepare everything by hand, since I don't get the option to install Windows 10 from Boot Camp, only 8 and 7. If I try to install Windows 10, Boot Camp says the OS is not supported.


  • Can I check if you're using bootcamp assistant, and if not is there anything preventing you from using bootcamp assistant? I ask because I haven't had much luck manually installing all the drivers for windows on a Mac. – Scottmeup Jun 21 '18 at 6:28
  • I tried, but it won't allow me to install Windows 10, only 7 and 8. I managed to install all drivers but audio has a more general problem. – FuzzeeLowgeek Jun 21 '18 at 8:50
  • Any chance you could update your question with the error you had trying to use bootcamp assistant with windows 10? I'm not 100% sure I've encountered that but someone else may have. – Scottmeup Jun 21 '18 at 13:05
  • Ok, done. Not much of an error, it just says W10 is not supported. – FuzzeeLowgeek Jun 21 '18 at 14:42

I have the solution for audio to work UEFI windows 10


This took 4 years to figure out

I did it like this: I let Bootcamp start installing Windows 8.1.

Then on the first reboot I booted from a setup DVD and installed Windows 10 over that, using BIOS mode. After I did all this, installing Boot Camp software in Windows gave me a fully working Windows 10, with audio too.
