Zap PRAM in Terminal - iMac

[Rocketfish]

I don't have a wired keyboard to enter the traditional Zap PRAM keystrokes. Has anyone used the sudo command "nvram -c" to accomplish this?

yup, using this command all the time. check content of NVRAM with "nvram -xp" before and after "nvram -c".

Thanks, mikeboss. Cover me. I'm goin' in...

Why?

Zapping the NV RAM is to reset the defaults. It doesn't matter what that shows.

it's a habit...

1. nvram -xp (so I can see the data)
2. nvram -c (clear NVRAM)
3. nvram -xp (to check if NVRAM is empty)

Ok, we all have our habits.

Has it ever once shown the NV RAM wasn't cleared? Just kidding—we both know the answer.

I'm with mikeboss on this one. Like to know what existed before NVRAM cleared.
