GUIDE How to Fix NVRAM on macOS [Clover/OpenCore]

[EliteMacx86]

Actually my native NVRAM is working as its Z600 series. Previously I messed up something that why its not working. I have removed emulated NVRAM. Sorry for the trouble.

Glad it is working for you now.

I checked both OC and Clover method, same result when run
nvram myvar
Result is:
nvram: Error getting variable - 'mylar': (iokit/common) data was not found

But:
nvram -p returned same value when reboot, and brighter light, sound level saved after reboot to check, specially iMessage working, so I think emunate nvram still working in my case, right?

Did you actually set any variable first?

As per your specs, you should have a native NVRAM. Emulation is required especially for older systems and where the firmware is buggy.

So, you're referring to your Dell one? If so, it should have a native NVRAM.

How about your health?

It's good now. Thanks for asking
Hope you're fine

I've done a NVRAM reset on my Mac Mini and now my monitor output dont work. I suggest everyone to avoid doing this at all cost.

There is a lot of reports of the same issue on the web and no solution.

Even when using OCLP, one should reset the NVRAM using the Command+Option+P+R Key combinations. That always work fine.
