Have you ever noticed that after extended usage, your Mac, Macbook, or Macbook pro seems to run just a little bit slower than it used to? Obviously you've still got to rule out the following basics:

1) Too many applications open
2) Too many Browser windows or tabs open
3) You've got some horrible website build 100% in flash, and it's slowly sucking your memory dry.
4) You have miraculously caught one of the few pieces of malware that plague macs.

Now just so you know... there is a price to pay for resetting the PRAM. There is information stored in there after all. So in case your volume changes, your clock might get reset, and your mouse may or may not move a little faster - here's a quick list of stuff that gets nixed:

* Startup disk
* Speaker volume
* Mouse scaling (mouse speed)
* Attention (beep) sound
* Double-click time
* Caret blink time (insertion point rate)
* Menu blink count
* Monitor depth
* 32-bit addressing
* Virtual memory
* RAM disk
* Disk cache
* Status of AppleTalk
* Serial Port Configuration and Port definition
* Alarm clock setting
* Application font
* Serial printer location
* Autokey rate
* Autokey delay

It's not the end of the world, but could be very irritating if you're dependent on iCal or another time based application to give you fair warning about meetings and what not. Sadly it does somewhat remove the DVD region setting as it's also stored in here for easier access, but you cannot change your DVD region using this technique.

Once you've cleansed your PRAM - give the machine another whirl and enjoy your extra (little, but noticeable) burst of speed.

Things You Will Need

4 fingers
(Option, Command, "P", and "R" keys on your keyboard)

Another finger
(to push the power button)

Step 1

Shut down the computer.

Step 2

Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4. (Keep in mind you will need one more available finger someplace to hit the power button)

Step 3

Turn on the computer. (duh)

Step 4

Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears. (somewhat of a Vulcan death grip, but a little more advanced than your typical PC CTRL+ALT+DEL)

Step 5

Hold the keys down until the computer restarts and you hear the startup tone for the second time. (if you're not sure what this sounds like as a non-mac user, go watch Pixar's Wall-E and listen to the sound he makes when his battery is fully charged)

Step 6

Let go of the keys! (yes, that means YOU)

Don't forget to reset your clock after trying this method (if it goes out of sync).

Tips & Warnings

Not that any of you readers would EVER do this, but don't forget step 6. I know it seems redundant to put that there, but if you don't let go, it resets the PRAM AGAIN and needless to say, will reboot your machine again. Unless you think your computer is fat, and needs to practice booting to lose weight, then I'd suggest you not forget the last step.
