Whenever something goes wrong in a unit, one of the first questions most technicians will ask is, "Have you Reset the PMU (or PRAM)?"

Q: Why do they ask this?
A: This is asked because resetting the defaults is like throwing a large net over small problems to make sure the problem isn't a simple issue before delving into the internals of the unit.

Resetting defaults is usually over prescribed and rarely fixes most issues it is prescribed for. However, it is free and an easy way of possibly fixing the issue. So, it is definitely worth a shot.

Basically, resetting defaults cleans out some stored settings on your machine. Cleaning out these settings can sometimes fix minor issues with your unit. Some of these settings include display refresh rate, system volume, DVD region, kernel panic information, etc.

The first command will also reset your non-volatile ram.

How to Reset all Default Settings:

1. Restart the unit and immediately hold down the Command (Apple), option, o, and f keys at boot. Your unit will boot into a prompt. At the prompt, type the following, hitting return after each line: reset-nvram set-defaults reset-all.

2. Your unit will now restart with the settings restored to their default state.
