Q: MBA mid 2011 2.9 Firmware update just killed by Air

I have a mid 2011 13 Macbook Air.

I downloaded and installed the (MacBook Air EFI Firmware Update 2.9) latest Apple firmware update.

The update seemed to install fine, then asked for a reboot.

 

The MBA shutdown and never came back on.

 

Tried SMC reset, with and without power adapter. Nothing. The thing is dead.

 

Out of warranty. No Applestore in this country (Greece). Retailer I bought it from doesn't want to know about it.

Local "official" Apple support will try and fix it for a fee of course.

 

Thank you Apple.

MacBook Air, OS X Mavericks (10.9.4)

    According to this:

    MacBook Air EFI Firmware Update 2.9.1

     

    The system requirement for the update is: MBA41.0077.B11, which I believe was last weeks EFI 2.9 that would not install on most MBAs, and that Apple later removed.

     

    The new 2.9.1 shows up in App Store software updates, even though I never succeed installing the EFI 2.9,

    I really don't know if I dare try to install 2.9.1.

    Can't imagine 2.9 being a pre-requisite since they pulled the update. It seems to be a totally new install for the EFI update. In any event, my installation went without a hitch. My Mid-2011 13" MBA now shows Boot ROM Version: MBA41.0077.B11 in System Report.

    It could be that the App Store is smart enough to know if you tried to install 2.9 before ... and if so offers 2.9.1? And for those who never tried the App Store may show 2.9? In any event, I was one of the first to participate in the thread and I tried to install 2.9 a few times. As I said above, 2.9.1 installed for me without any issues whatsoever.

    Anyway I just dared to install the EFI 2.9.1 update, and everything went smooth.

    Before update: MBA41.0077.B0F

    After update: MBA41.0077.B11

    From the old log that EdisonW had posted on 22 July 2014 ...

    The internal version has not changed but the content seems to have changed.

    Hello Loner,

     

    I've just successfully installed the new 2.9.1 EFI update onto the same machine from which Apple harvested the diagnostic logs from my case number, and can confirm it installed with no issues, and the Boot ROM Version is now "MBA41.0077.B11".

     

    I can also confirm the wireless, cooling, and all other systems are running as they should! The only thing I've noticed, is when the machine shutdown to perform the installation, the screen still went dark for about 4 seconds before the traditional grey screen with a progress bar.

     

    Other than that, everything looks like it's back to normal. I think it's safe to say this issue has been resolved with 2.9.1.

     

    What I'd love to hear, is if people here who've experienced non-bootable MBA's after the original update, can get their system running again using some of the troubleshooting steps that have been documented here, and then install the new update and report results...

     

    Cheers

    I am glad new 2.0.1 update came out for those hwo are out there. But my mid-2011 MBA became non-bootable after 2.9 update. And none of the steps provided through this forum solved problem. I am currently out of luck but to decided whether to pay to fix it or not which was really unnecessary.

    After the failed installation of 2.9 last week (x2) and although Software Update history indicated I installed it twice, I suspect the 2.9 was never actually installed in my MBA since the System Report indicated still having BOOT ROM Version: MBA41.0077.BOF (EFI 2.4) which was the latest listed at EFI and SMC firmware updates for Intel-based Macs

     

    I just installed EFI Firmware update 2.91 and had no problems whatsoever (new BOOT ROM Version: MBA41.0077.B11). Therefore, having 2.9 installed is not a pre-requisite for the installation of 2.91.

     

    Issue resolved!

     

    Many thanks to Loaner T and all others in this thread.

    Did you pay any money to get the logic board replaced? If yes, I suggest you take it back to the store, show them the 2.9.1 update release, the Console logs from the failed update, and talk to the Store Manager for a possible refund. If EdisonW gets clearance to post his case number, you can also take it with you.

     

    This is poor customer service.

    No, I didn't pay anything and I still do have my bricked-non-working-MBA.

    Apple Genius Bar person couldn't do anything but to suggest to pay it and fix it.

    But I didn't want to. Because it was simply not my fault at all.

    How did that happen? From your previous posts it seamed that your MBA became non-bootable after 2.9 ?
