[Solved] Your computer was restarted because of a problem

[Natural]

I also get this error:

nvram: Error clearing firmware variables: (iokit/common) not permitted[code]

Can't seem to clear the NVRAM file. Can't find it anywhere.

In the same boat. Haven't found a solution yet

Despite the error message, the NVRAM has been cleared. Found this on another forum that proves it out:

Cyberdevss-iMac:~ cyberdevs$ sudo nvram TestVar=HelloWorld
Cyberdevss-iMac:~ cyberdevs$ sudo nvram -p | grep 'TestVar'
TestVar HelloWorld
Cyberdevss-iMac:~ cyberdevs$ sudo nvram -c
nvram: Error clearing firmware variables: (iokit/common) not permitted
Cyberdevss-iMac:~ cyberdevs$ sudo nvram -p | grep 'TestVar'
Cyberdevss-iMac:~ cyberdevs$

Thank you this resolved my issue too!

Hello @deegee
Sorry to ask, but I followed the same thread where some person commented recently below this example code, that this command only proves that "TestVar" was flushed, but not the entire NVRAM.. Anyone here to prove this wrong again ?

Thank you
