nvram error
I tried to reset nvram(or pram) with the terminal app.
I put sudo nvram -c and the terminal said
Error clearing firmware variable fmm-computer-name: (iokit/common) not permitted
and couldn't reset nvram.
Are there any way to overcome or detour this error message and to reset nvram(pram)?
I'm using 2017 mbp with 2 thunderbolt ports.
Thanks
