EFI Firmware Update

Apple today issued an EFI Firmware Update for its 2.2GHz and 2.4GHz 15-inch MacBook Pro models laptops that fixes a display issue. Apple's MacBook Pro EFI Firmware Update 1.3 is used to create a Restoration CD by downloading the necessary file from the company's website, and when used restores the firmware of an Intel-based Mac if for a previous firmware update attempt was interrupted or somehow failed. Apple offers step-by-step instructions for restoring a computer's firmware, which include burning the restore CD and using it to replace any corrupted firmware that may reside on an Intel Mac. The firmware update requires MacBook Pro Software Update 1.0 or later, which is also available from Apple's website.

Firmware restoration instructions

To restore your computer's firmware, you must first create a CD using the disk image named "FirmwareRestorationCD.dmg" by following these steps:

1. Open Disk Utility (located at /Applications/Utilities).
2. Click the Burn icon or select the "Burn..." menu item from the Images menu.
3. Navigate to where FirmwareRestorationCD.dmg is located, and click the Burn button.
4. Insert a blank recordable CD.
5. Click the Burn button to create the Firmware Restoration CD. The files are burned to the disc.

Next, use the Firmware Restoration CD to restore your Firmware:

6. Ensure that the computer you are trying to restore is plugged into an AC outlet.
7. Turn on the computer and continue holding down the power button until the LED blinks rapidly followed immediately by a successive series of blinks (three quick blinks, three slow blinks, three quick blinks). Insert the Firmware Restoration CD while the lights are blinking, then release the Power button.
8. Insert the Firmware Restoration CD. You will hear a long tone once the recovery process has begun.

A progress bar appears beneath an Apple logo on a gray screen. The progress bar indicates the firmware is being updated. Do not unplug, shut down, or restart the computer during the update or you will need to start the restoration process again beginning with step 6.

The computer will restart automatically after the firmware is updated.

    Maybe but...

    This firmware update still has not fixed the rash on my hand. And if I do get rid of the rash and then use the restore CD later, will the rash return? You bet it will.

    Thanks Apple.

    Rolling bands

    After a successful installation, I went from problem free display to one with rolling bands of brightness down the screen.

    I did not have any problem that the update was supposed to solve, but I actually introduced a problem instead!
