The explanation for this is:
The 'Starting Mac OS X' progress bar is faking it!
O RLY? YA, RLY!
Here's how it works. At that point in the boot process, OS X is loading kernel extensions and other low-level stuff. However, during this process it also creates a cache -- a streamlined, optimal way to load these modules. Ordinarily, the system will boot from this cache, but if any of those modules change, it needs to drop back to a standard (slow) load to rebuild the cache.
So, what's this got to do with the progress bar?
Well, since there's no set speed at which these modules can be loaded, the system records how long it took to load them during each boot. At the next boot, the progress bar simply grows based on how long the machine thinks it took to load them last boot.
Let's imagine your system's got an optimised cache and has booted a couple of times so it's got a pretty certain idea how long it takes to load that cache. The 'Starting OS X' screen will therefore disappear at just about the same time as the progress bar fills.
Then, you install an update which needs the cache to be rebuilt. The progress bar zips to the end (as it did when using the previous cache), but then the system hangs about as it's still loading the modules and rebuilding the cache. After this boot, the system records that it took ages to load up.
Next reboot, the system's using the newly-built cache, but the recorded time for the modules to load is still lengthy as it was recorded during an uncached load. The progress bar will only get part-way through before the Starting OS X window disappears.
Finally, on the next reboot, the cache and the time-to-load timer are synchronised and you're back to normal!
Neat, eh?

I trashed the EFIUPdate1.3.app but somehow it said my firmware is already up-to-date and didn't allow me to reinstall..
now the EFIUPdate1.3.app icon is gone, but after resetting the PRam monitor is running fine again. 😕
I managed to install the update on my 2.2 SR MBP without too much trouble.
The battery time appears to have improved but if anything, my screen is less bright compared to before!!!!
Should I try and do a PRAM reset???
PS. I have installed bootcamp and also find that the mac os takes longer to boot up now. May be I should have gone for parallels instead.

Hehe yeh - it is just an animation too. You can bring it up at any time.
Load up Terminal and type /usr/libexec/WaitingForLoginWindow and wey, there it is! To get rid of it, just type killall WaitingForLoginWindow
I installed the update too, and had the rolling bar problem.
Followed the advice of doing the PRAM/NVRAM reset, but it didn't work.
My Mac booted up like normal, only heard one chime, I had to be doing something wrong.
About 20 reboots later I realised I somewhere set a password on the EFI when I just got the machine. Found the application "Firmware Password Utility" on the first install disc, ran it, disabled the password and rebooted with the command+option+p+r. Finally, my pram got zapped and my rolling bar issue seems to be gone.
Thought I'd put it here, maybe someone finds it useful.

Had to do the command+option+p+r on reboot thing now bands are gone but now the machine is noisy, running extremely hot.
What to do, can i go back to the previous version. I had no issues than.
Thanks

Zig Zag Screen Issues on MBP LCD 2.4 Intel Duo
Was wondering if anyone else had issues when looking at images at 100% or larger in PhotoshopCS3, where the display freaks out and displays the image all zig zag like a out of tune television... I get this happening with my Samsung 215w extrenal screen hooked up and I have tried to setting both monitors as the main display and it happens on both settings. Wondering if this update will fix it???

Ripply Effect be gone!!!!
So as I was sitting on my macbook pro I realized I had the symptoms of the 1.3 fix error. As I searched far and wide for an answer I stumbled on the forum. I tried the pram reset several times with no avail. As I was reading I noticed that it was almost like I had zoomed in a little but my screen looked of normal proportion. I simply zoomed in one more step then back out and it fixed the issue; however, if I zoom in one step I do see the blocks and the rippling but only one step in. My conclusion is that it got stuck a half step in on magnification and it was hard for the eye to see. Worth a shot!
Cheers

I installed the update earlier this week, but haven't seen any improvements...detriments only, in fact. I had some problems with Expose last night, and whenever I close my lid it takes forever for the backlight to go out (where as it used to shut off right away). Wonder if it would be worth rolling back...? What exactly did they try to fix with this update anyway?

MacBook Pro vertical gray lines problem solution
I have been struggling and racing anyone's brain who knows anything about Macs concerning vertical gray lines that appear on my new MBP. I think I found the solution and it wont mess up your MBP if you do it. You need to reset your PRAM. In order to do so you should first write down these instructions. first: shut down your MBP. Second: turn on again. Third: IMMEDIATELY after turning back on hold down "command" "option" "P" and "R" keys AT THE SAME TIME. Fourth: Hold down all 4 keys and keep holding down keys until you hear A SECOND BEEP. One that happens, your MBP will start up and bring you to your regular desktop everyday looking start. Fifth: once it looks like your regular desktop after turning on, click on the apple in left-hand corner (Apple Menu). Sixth: click "System Preferences". Seventh: click the "startup disk" icon in menu that come up. Eighth: make sure you click the icon that says Mac OS X. Ninth: after selecting Mac OS X icon click the "restart" button in box. If you like you can lock the setting to make sure your MBP will always go with the right startup disk. MAKE SURE YOU KNOW YOUR MAC username and password as you will need to enter both in order to remove the lock. to lock on the Mac OS X icon simply click the apple in top left-hand corner (Apple Menu) then click "system preferences" then click the Mac OS X icon (it should be highlighted) and at the bottom of that window should be a lock that you simply click and then click the "restart" button on same window. This procedure MAY change some settings but In my experience, nothing has changed as to my knowledge. BUT I MUST WARN THAT THIS MAY CHANGE SETTINGS AND/OR PREFERENCES, but can all be re-set by you back to your personal preference.
MOST IMPORTANT: the most important thing is to hold down keys until you hear second beep AND more importantly, you have to select the Mac OS X icon through the Apple Menu. Simply shutting down and turning on holding keys DOES NOT FIX PROBLEM..... ALL STEPS MUST BE FULLY COMPLETED except for the locking option.
