How to reset mac PRAM through the command line in Lion/Mountain Lion?
Solution 1:
Mountain Lion does not have this functionality, but Mavericks does!
Resetting the PRAM is now as simple as running the following command as root:
nvram -c
According to the man page for the nvram command (in Mavericks):
-c Delete all of the firmware variables.
I should note that this also works all the way up to and including Sierra.
