Mine updated without any problem too.
It does boot faster now, for the rare times I need to shutdown/reboot.

Same here too. Mine is also late december, also a custom build (hi-res matte screen + CPU/GPU upgrade + SSD), but other than memory I've done nothing to it myself. Also on B26.
i just tried this until a member here suggested i reset my pram and i did. this still came up. I have the 13" macbook pro i5. 2.4Ghz. 500Gb. 4Gb of memory, late 2011 model. I just got this laptop as a gift almost 2 weeks ago. What would be causing this?

He's probably just jealous that somebody had the balls to download a torrent for the Developer Preview, install it and have it properly running. Not that he is missing out on much. The current incarnation of Mountain Lion is sluggish like hell and does not bring one single feature that's noteworthy - the toy apps don't count and Dungeon Keeper is a reason NOT to upgrade; Apple is moving in a direction that should not be supported.
For Mac OS X 10.7.3 onlyI refuse to install 10.7.3 (sticking with 10.7.2) because of some bugs that it causes.
Not cool. Why isn't 10.7.2/SL supported?
Supporting the upgrade on old OS versions would require a lot of extra testing, delaying the release and increasing costs. Apple are right to support firmware updates only on the latest OS release.
Because your MacBook Pro already has the necessary fixes; when the updater runs it checks the model and EFI version then it decides whether you need to update - according to that you don't need to update. Listen to the installer - it knows best.

I just updated my late 2011 27" iMac and it wiped my SSD boot drive clean! Just restoring now from my timemachine backup, only 1h50m left!!!!!! :-(

People with 1866MHz RAM were getting kernel panics not because there is no support for 1866MHz RAM
(there IS support for 1866MHz RAM), but because there is no support for CL11 RAM.
1866MHz CL9 RAM (when it will come out) would be just fine!
Please, could you check the Boot ROM version of your MBP?
http://support.apple.com/kb/DL1499 - states that it should become MBP81.0047.27,
but I have got MBP81.0047.B27 instead!

This latest EFI update does nothing to improve the usability of a 6Gb/s SATA 3.0 link connection in the 15/17" 2011 optical bays. If your system profiler reports 6Gb/s link in that bay and you plan to add a drive there - you must select a SATA 2.0 3Gb/s drive as the factory hardware and/or other particulars was not qualified to support 6Gb/s and it is NOT RELIABLE there with. Apple only uses that bay for optical drives that still link at 1.5Gb/s and would have done upgraders a service by using the 3Gb/s port link in that bay if not just properly supporting 6Gb/s in the first place there... but they have no reason to with respect to optical drive primary and only factory intended use.
We haven't given up and have a possible solution in the works we'll be able to test soon- but this isn't just some shielding. Also - it's far more likely that success will be found with the current gen Late 2011 version models vs. the original Feb/early 2011 models. The late 2011 starts off far far better right out of the gate - although not quite there vs. the earlier models that are, well, far far worse for the same.
We'll see. Been covering this on our blog for a long time with never ending testing across the board.
This update seems to have wiped away all my remembered wifi APs and passwords, and my firewall exceptions. :-(
I hope this fixes my slow boot up issues. Takes around 2 minutes for it to get to the login screen. Not happy!
Seem to work fine, maybe its me but booting up seem a slight slower now about 2 or 3 second slower on my Macbook Air 2011.
But all else seems ok, at least my WiFi issues are gone not that I had to much issue more of an inconvenience than real issue.

Is your update turned on?
