Apple's MacBook Pro EFI Firmware Update Improves Boot Camp
Apple's MacBook Pro EFI Firmware Update Improves Boot Camp
by , 5:15 PM EDT, September 27th, 2007
On Thursday, Apple posted a MacBook Pro EFI Firmware Update 1.4 that improves the performance and reliability of Mac Book Pros with Intel Core 2 Duo processors and fixes issues with Boot Camp on those systems.
The update will appear in Software Update for those users of MacBook Pro, Core 2 Duo Systems.
Apple said in the update, "After the firmware is successfully applied to your computer, your BootROM Version will be one of the following:
- MBP21.00A5.B07
- MBP22.00A5.B07
- MBP31.0070.B03
Observer Comments
I have the exact same computer and performed the update without a hitch.. Had the menu bar and everything went smoothly. I am the guy that actually prints out the instructions before performing a "firmaware" update. I know they can be kind of fussy to install correctly. All in all, after the download and the automatic restart to the EFI Firmware telling me the update was sintalled properly was about 4-5 minutes tops. I'd recommend just checking out the detailed instructions ahead of time and making sure you hold the power key down until the sleep LED flickers like crazy. Thats when I let go then heard the long tone (freaked my cat out) and then I got the menu bar.
First time posting and I apologize for the rambling... Hope this helps.

I was able to memorize the two step's to do after the MacBook shuts down [namely hold the power button down until you hear the tone, then wait for it to restart]. The update process took maybe 2 or 3 minutes and then rebooted automatically. Haven't rebooted into BootCamp, but Mac OS X 10.4.10 still seems happy.

I was sitting in the dark and didn't notice the black USB drive cable was hooked up. As I mentioned in the first comment my Macbook Pro was locked up for over an hour before I aborted (didn't know if it would reboot - it did). Second time worked fine (once I unplugged the USB drive)
So.. make sure you unplug any external drives before pressing the power button!
