Clover Reset PRAM?

Clover Reset NVRAM?

I was just wondering how one goes about reseting the NVRAM on Clover? I knew how to do it on Chameleon.

I tried to google this but couldn't find a clear answer...

Thanks...

nvram -c

Where?

Where?

At clover boot screen select shell icon, type in the terminal it opens up.

Thank you! Sometimes people who knows think it's obvious, but for newbies like me it's not

By the way: I discovered it's not at the boot screen where we should use it: it's within the Terminal, while MacOS is working. I also learnt more alternatives:

To clear the values:
sudo nvram -c

To display the values:
sudo nvram -p

To display the values, including the SmUUID and other IDs stored there:
sudo nvram -x -p

do these nvram settings have any effect outside of osx? i mean if set incorrectly could they lead to problems with other windows or linux?

Hi guys! Thank you for the votes . @FCerv, I'm not sure if it affects other OSs installed. In my experience it doesn't affect my Windows at all, and fixes my hackintosh when it starts acting weird (random kernel panics, doesn't go to sleep, problems with iMessage, etc.). I'm not yet sure what it gets corrupted from time to time. I'm not even 100% sure if the NVRAM is the actual NVRAM from the mainboard or it's also emulated by Clover. As I get more info I'll share it

UPDATE: I found out some boards are compatible with a native NVRAM and some don't. Those need emulation with a tool called EmuVariableUefi-64.efi. It's recommended to use the native one because it tolerates better kernel panics and unexpected reboots while with emulation, a clean boot is required to save data to the NVRAM properly.

Question, if I clear the nvrm, will MacOS automatically populate new values into it upon next reboot? Or we have to manually populate the nvrm so that MacOS can boot up correctly?
