MacBookPro EFI Firmware Update 1.5.1 won't load

[A1bsteg]

Each time my MacBook Pro checks for software updates, I am told that MacBook Pro EFI Firmware Update 1.5.1 is available. I click on install, the installer runs and says installation was completed but the next time I check for updates, there it is again. I've tried to install several times, but System Profiler still does not show the updated firmware version number, so it apparently hasn't installed, regardless of what the update installer tells me.

Any ideas?

Just check the instructions for installation.

Yea, power down the computer. Then hold in the power button until you hear a long tone and it will begin the update

You have to manually install it. Look in your /Applications/Utilities folder and you should find the file there. Launch it and follow the instructions EXACTLY.

The next time you launch Software Update, you won't see it in the list and after you apply the update, the System Profiler will show a new firmware version number.

Thank you. I never would have known where to look for the installation program or that it had to be installed manually. There was no indication at all in the Software update dialog. Once I knew where to look and what to do, it worked just fine! Thanks again.

Broken/Incomplete Update

I had the same problem, but when I hunt down the update in my Utilities it says it is damaged or incomplete...?
