    *****UPDATE SOFTWARE UPDATE JUST PRESENTED ME WITH FIRMWARE 2.7 UPGRADE SO DISREGARD THE BELOW INFO****** (It installed without issue)

    I think I maybe able to put you minds at ease. I have two MBP 17" late 2011. Once purchased in November of 2011 and one purchased this past Sunday 2/25/12. The MBP purchased in November required, accepted and installed the 2.7 firmware. The one most recently did not present the download in the software update panel, did not install it when I manually downloaded the firmware update and kept presenting me with the info "This system does not support this update." (BTW I tried to install 2.7 on a stock Lion drive with no other software installed on the most recently purchased MBP, no luck)

    Here is my Sunday's purchase profile: Note the boot rom is different then what the Firmware 2.7 states it should be. My theory is that there was a hardware change in the units produced mid December or early January to now that nullified the 2.7 firmware upgrade. Go to http://www.chipmunk.nl/klantenservice/applemodel.html and enter your serial number to find out exactly when your MBP was made. I will venture to bet all those that can't install the 2.7 firmware were made after late December 2011 or early 2012 to present. I believe there is no concern if your mac is not displaying any issues. HOPE THIS HELPS...

    Hardware Overview:

    Model Name: MacBook Pro
    Model Identifier: MacBookPro8,3
    Processor Name: Intel Core i7
    Processor Speed: 2.5 GHz
    Number of Processors: 1
    Total Number of Cores: 4
    L2 Cache (per Core): 256 KB
    L3 Cache: 8 MB
    Memory: 8 GB
    Boot ROM Version: MBP81.0047.B26
    SMC Version (system): 1.70f5

    This is when my recent MBP was made and this is the one that I believe does not require the 2.7 firmware:

    Model introduced: 2011
    Production year: 2012
    Production week: 7 (February)

    This is mine. I just got my laptop on February 26, 2012 :) I guess mine doesn't apply to the firmware update as well. I can sleep now!

    Just did this for my 2011 Mac Mini that wasn't getting the upgrade. Shows my Mini was made in December 2011.

    Couldn't apply the update to my refurbished Late 2011 MBP and checking that site gave me a build date of sometime in January.

    I think my theory maybe correct then. Built after mid December 2011 till now did not require the update.

    The strangest thing just happened... the update appeared in my software updater tonight. However when downloading it the other day and trying to manually install it I couldn't. Strange.

    Haha oops, just realized you updated the post. Disregard.
