There are a few ways to do this.
Method 1 Create a new user account, making sure to give the user Admin access. Once you create this new user, log into the new user account and delete the old user. This is the quickest and easiest way(this works best with 10.5, if you're running 10.4 or earlier try method 2.)
Method 2 Take the install disc and reboot your computer with the disk in the drive. On start up, hold the "c" button. Now you can re-install the operating so you can have a clean start. (if you don't have the install dvd, refer to Method 3)
Method 3 Delete all the unnecessary applications, once done create a new user with admin privileges. Log in with this account and delete the old account. This way you won't have any of the programs you don't want and the new user will have factory account settings. As close as you can get to a fresh start.
No matter what method you choose, be sure to back up important information.

Resetting the PRAM may do the trick:
You reset the PRAM by rebooting a Mac and then immediately hold down the Command+Option+P+R keys, you will then hear the Mac reboot sound again, signifying your PRAM has been reset. You must hit the key combination before the grey screen appears otherwise it won't work.

you've tried rebooting, you've reset the PRAM, you've done it all, but your Mac is still behaving strangely. What next? In certain circumstances, resetting your Mac's System Management Controller (SMC) can be a solution. This is sometimes necessary to restore normal lower level system functionality to your Mac.

Here's how to reset the SMC on any type of Mac (and any version of OS X) and the type of problems that it may resolve.
When & Why Reset SMC on a Mac? Some Common Hardware Reasons

Typically it's power and hardware related issues that can be helped or resolved by resetting a Mac SMC, particularly if you're having these types of problems:

* Issues with your Mac's cooling fans and fan management: fans run constantly at high speed, fans run high despite low CPU usage and adequate ventilation, fans not working at all, etc

* Power management and battery problems: Mac isn't turning on, sleep isn't working, random shutdowns and reboots, battery isn't charging, Mac won't wake from sleep etc

* Light problems and improper lighting management: battery indicator lights aren't working, display backlighting isn't adjusting to ambient light changes, keyboard backlights not working, etc

* Video and external displays not working: display brightness functionality not working properly, target video mode isn't working properly, external display isn't working, etc

* General performance and functionality problems: abnormally sluggish behavior despite no CPU or disk usage, external ports not working, airport & bluetooth aren't showing up, external devices are not being found, etc

So now that you've concluded you need to reset your SMC (Note that the SMC is on Intel Mac's only), here's how to do it on MacBook's, MacBook Pro's, iMac's, Mac Mini's, and Mac Pro's. Notice that the reset instructions are different for MacBook and MacBook Pro's if you have an internal or detachable battery.
Reset SMC of a MacBook Air, MacBook Pro Retina, or MacBook Pro's with an internal non-removable battery

This is how to reset SMC on most modern Mac laptops:

Shutdown your MacBook Air / MacBook Pro
Connect the power adapter to your Mac
On the MacBook/Pro's keyboard, hold down the Shift+Control+Option keys and the Power button at the same time
Release all keys and the power button at the same time
Boot your Mac as usual

Here's the key sequence to hold down:

Reset the SMC of a MacBook Air or Retina MacBook Pro

Do keep in mind that by resetting the SMC you will lose power specific settings, like the time it takes to sleep a Mac and other customizations to power settings. No big deal, but if you have made many changes to your hardware behavior you will want to adjust stuff like sleep behavior again.

Resetting SMC is different for non-portable Macs:

Press and hold the Mac's power button for 5 seconds
Release the button

Reset the SMC of a MacBook or MacBook Pro's with detachable batteries

Shutdown the MacBook/Pro and remove the battery
Disconnect the power adapter, hold the Power Key for 10 seconds
Release the power key and reconnect your battery and power adapter
Turn your Mac on
Let boot as usual

Hopefully that will clear up your problems, if not it might be worth a visit to the Apple Store or a certified repair center.

MacBook Pro is slow when disconnected with electric charging.


First step would be to Reset Your Mac's SMC
The method for resetting your Mac's SMC depends on the type of Mac you have. All SMC reset instructions require shutting down your Mac first. If your Mac fails to shut down, try pressing and holding the power button until the Mac shuts down, which usually takes 10 seconds or so.

Mac portables with user-removable batteries (MacBook and most MacBook Pros):

1.Shut down your Mac.
2.Disconnect your Mac portable from its MagSafe connector.
3.Remove the battery.
4.Press and hold the power button for at least 5 seconds.
5.Release the power button.
6.Re-install the battery.
7.Reconnect the MagSafe connector.
8.Turn your Mac on.
Mac portables with non-user-removable batteries (MacBook Air and some late 2009 MacBook Pro models):

1.Shut down your Mac.
2.Connect the MagSafe power adapter to your Mac and to a power outlet.
3.On the built-in keyboard (this will not work from an external keyboard), simultaneously press and hold the left shift, control, and option keys while you press the power button. Release all keys at the same time.
4.Press the power button to start your Mac.

Mac desktops (Mac Pro, iMac, Mac mini):

1.Shut down your Mac.
2.Unplug your Mac's power cord.
3.Press and hold the Mac's power button for 15 seconds.
4.Release the power button.
5.Reconnect your Mac's power cord.
6.Wait five seconds.
7.Start your Mac by pressing the power button.

Alternative SMC reset for Mac Pro:

If you have a Mac Pro that isn't responding to the normal SMC reset as described above, you can force a manual SMC reset by using the SMC reset button located on the Mac Pro's motherboard.

1.Shut down your Mac.
2.Unplug the Mac's power cord.
3.Open the Mac Pro's side access panel.
4.Just below the Drive 4 sled and adjacent to the top PCI-e slot is a small button labeled SMC. Press and hold this button for 10 seconds.
5.Close the Mac Pro's side door.
6.Reconnect your Mac's power cord.
7.Wait five seconds.
8.Start your Mac by pressing the power button.
Now that you have reset the SMC on your Mac, it should be back to operating as you expect. If the SMC reset didn't fix your problems, you can try combining it with a PRAM reset. Although the PRAM works differently than the SMC, it can, depending on your Mac model, store a few bits of information that the SMC uses.

Garmin nuvi turns on, but goes black after attempting to load maps.


Try and connect the Nuvi to a PC / Mac using an USB cable. Connect the cable first before powering the PC / Mac - make sure the Nuvi is powered off.

Then turn on the PC / Mac. The Nuvi should go into communication mode making it possible to update the internet software (if available on MyGarmin.com). This might fix the problem.

If there's no software update available at MyGarmin.com - try a master reset. This will clear all user data (POI's / Favorites, Tracks, routes) going back to factory defaults.

A master reset is started by pressing the lower right corner for at least 20 seconds while pressing the power-on button once. A question appears to clear all user data.

How do I do a master reset on the pro 83 scanner


To reset the scanner (clear a problem or keyboard lockup):
- Tune the power OFF and then back ON.
- Insert a pointed object (paper clip, ballpoint pen tip, etc) into the RESET opening on the side of the scanner and gently press the button inside.

If the RESET does not clear the problem you can INITIALIZE the scanner, but this procedure will clear/erase all information that you have programmed into the scanner.
- Power the scanner OFF and then ON.
- Press and hold the TUNE/CLEAR button while pressing the reset button as above. The display will momentarily blank.
- When the display resumes, press TUNE/CLEAR again.
