Hi, the use of the patch AppleXcpmCfgLock is highly discouraged as can cause all kinds of system instability due to the fact that patching AppleIntelCPUPowerManagement.kext is a very bad idea.

Also, SuperIO sensor reading support [in your case, Intel_EC_V8] has been added for NUCs, check out this page:

https://github.com/acidanthera/VirtualSMC/blob/master/Docs/EmbeddedControllers.md

In your case, the sample patch matches your NUC model. A deviceproperty patch is all you need, alongside the latest VirtualSMC build coming on April 5th or from here

Hi,

Both HDMI and Thunderbolt work independently, but only HDMI or Thunderbolt work when connected at the same time, it depends on who connects first.

Any suggestions on how to make them work at the same time?

Thanks.

First thank you for your contribution,this EFI work fine on my machine.

But the sound card does not seem to work properly. When the iphone earpod is inserted into the front 3.5mm headphone jack, there is no sound when it is inserted completely, and there is sound when it is inserted halfway.

It will restart after sleep wakes up

Looking forward to your reply

Hi

I've found your repository just now, after I have already setup my Nuc.
It's working almost everything except mSD card reader (I don't about Thunderbolt, becasue I don't have any device to test).

Any suggestion on how to let the card reader to work?

Thanks

This EFI is perfect for my NUC8 except the headphone jack.

I installed dual system on two separate disks, one is Windows 10, and the other is Mac OS Big Sur. If the Windows is booted from oc, the headphone jack doesn't work. But if the Windows is booted without using oc, it just works. I'm new to oc, and can't figure it out. Hope can get help here.
