MacBook Software Updater - continually prompts to install an update

My Mac Book Pro keeps prompting me to install "MacBook Pro EFI Firmware Update 1.5.1" through the software updater.
I have previously installed both through software updater and manually, but it still keep prompting me to install.
This is not the first time software updater has prompted me for previously installed updates, however this has usually been resolved through manually installing the update.
Any thoughts?

You're probably not actually flashing the firmware, but downloading the utility to do so. Follow these steps:
1. Quit all other open applications. Open the MacBook Pro EFI Firmware update which is in your Utilities directory

2. Click Shut Down in the MacBook Pro EFI Firmware Update window and wait for your computer to shut down.

3. Press and hold the power button on your MacBook Pro until the power indicator light flashes repeatedly, then release the power button to begin the update.

A status bar indicates the progress of the update.

Important: Do not interrupt the update.

Your computer restarts automatically when the update is completed and opens the MacBook Pro EFI Firmware Update.

4. Click OK, if the firmware is now up-to-date.

My laptop has suddenly frozen, i turned it off by the power button and whenever i try to turn it on it turns white screen, then shutsoff after 3-5minutes.


Resolution
  1. Disconnect any devices connected to the computer including printers, hubs, and third-party keyboards or mice, and test the computer again by trying to turn it on.
  2. If you're using a MacBook or MacBook Pro, check the battery level. Press the small button on the battery or on the side of the computer. You should see lights indicating the battery's level of charge. If you see just one light blinking, the battery needs to be recharged. Use the computer with the adapter connected to recharge the battery.
  3. Unplug the power adapter from the electrical outlet and from the MacBook, MacBook Air, or MacBook Pro. Wait one minute. Plug it back into the wall first, then to the computer. Make sure the electrical outlet is working by plugging in another device (such as a lamp). When you plug the adapter back into the computer, the power adapter LEDs should light up green or amber.
  4. Inspect the MagSafe port on the computer for debris, such as metal stuck to the magnet in the port, which might prevent the connector from seating properly. On the adapter side, look at the DC connector for dust or other debris and check whether pins are missing, bent, or stuck down. If you find any of these to be true, see Apple Portables: Troubleshooting MagSafe adapters for instructions on cleaning the adapter.
  5. Make sure you are using the adapter that was designed for your computer. If you aren't sure or if you need a new adapter, learn which adapter is appropriate for your computer.
  6. Press the control key, the command key, and the power button simultaneously and hold for three seconds to try to restart the computer.
  7. Reset the PRAM. After pressing the power button, hold down these keys simultaneously: Command-Option-P-R, until you hear the startup chime at least one additional time after the initial startup chime.
  8. Reset the SMC for the MacBook And MacBook Pro by removing the AC power, removing the battery and then holding down the power button for five seconds. On the MacBook Air, press (left) Shift-Control-Option along with the power button once. Note: You must use the keys on the left side of the MacBook Air keyboard.
  9. If you recently installed additional memory, make sure it is correctly installed and is compatible with your computer. Remove the new memory to see if the computer starts up properly without it.
Also:
The MacBook SMC Firmware Update v1.1 improves the MacBook's internal monitoring system and addresses issues with unexpected shutdowns. This update is recommended for all MacBook systems, including those that received warranty repair.
You can use the Software Update feature of System Preferences, or download the MacBook SMC Firmware Update v1.1 from Apple Software Downloads.
Note: If your MacBook is running Mac OS X 10.4.6, you won't be able to see the SMC Update until you update to Mac OS X 10.4.8. Once you have updated your system software, the SMC Update will appear as an option in Software Updates.
MacBooks running Mac OS X 10.4.7 will be able to download and install the SMC Update, so it is not essential that you update your system software, although Apple always recommends updating to the latest version of the system software.
If your MacBook is in a state where it will not remain on long enough to install the update, wait for the issue to reproduce itself. Once the MacBook has turned itself off, turn the computer on by holding the power button down. Keep the button down until you hear a single long tone. Once you hear the tone you can release the button, install the recommended updates, and restart normally.

I have a macbook pro and I am "locked out" from updating software


Insert your Mac OS disk into the cd drive and restart while holding the C key to launch the system on the disk instead of your hard drive.
When you reach the desktop, look for the utilities menu and reset the master password.
You shouldn't need the existing password to do so.

Can't install mac osx 10.5.7 combo update on 10.5.2


The 10.5.7 update sometimes does several automatic restarts - depending on the mac and the previously installed OS version.
In my opinion the 10.5.7 update has been the strangest I have done.
Try this.
Hold down the power button for about 10 seconds. The MacBook should now be off - but it may restart automatically while flashing the sleep light at you - and make a long beep noise. Don't worry if that happens just let it do whatever it does. Watch the screen and follow any prompts that come up.
If the MacBook did not turn itself back on, hold the power button down again for about 10 seconds. What happens now?
Don't press any other buttons unless the computer tells you to.
If however, you end up with another 3 hour wait then something is definitely wrong and you need to take it in to a specialist.

Software Update program not working


Some updates are intended ONLY for Macs running on PowerPC processors, while others are ONLY for the Intel processor. Most of them are Universal Updates for both processor families. Don't dispair, and read on the Apple website the detail for the updates issued (about weekly on Tuesday) to see if the update applies to your platform.

Macbook extra fan


The real issue seems to be that the system firmware designers haveoptimized for a quiet machine at the expense of the temperature. Theeasiest way to fix this? A firmware update,perhaps not unlike the one released recently with almost no details.Several reports from users indicated this update increased the use oftheir fans and fixed their heat issues. Isn't that an astonishingcoincedence?

Although Apple said that the update was to "System Management Control(SMC)" firmware, it was up to MacBook Pro (MBP) users to figure outthat SMC is the specialized controller that manages thermal and power conditions, and is in charge of running the portable's fans.
Within hours of the update, users began reporting that the updateseemed to increase the MacBook Pro's use of its fans, and usingdiagnostic tools, claimed that their machines were running up to eightdegrees cooler.
