MBA mid 2011 2.9 Firmware update just killed by Air

HELLPPP!! My macbook died after the firmware update. Worst of all, this is NOT the first time. I had it repaired 2

months ago. But the problem still comes back. Why am I

paying when my computer isnt actually fIxed? APPLE PLEASE FIX THIS ISSUE OR GIVE ME A NEW MACBOOK AIR.. My parents' macbook airs are fine! pleaaasseeeee!!

I also have keyboard issues, although not dead keys after the 2.9.1 firmware installation. After the 2.9.0 installation failed and black-screened, I was able to get my mid 2011 11 inch MBA to reboot into the old firmware. It was very unstable after that, crashing outright, or displaying the spinning beach ball. I installed the 2.9.1 update and the crashes appear to be fixed, but now i have a problem with my keyboard whereby apps can not keep up with my typing speed.

I am a slow touch typer, and after 2.9.1, I can now type full sentences before the text appears on-screen. Its like the mac can't read the keyboard buffer fast enough. I've never experienced this slow appearing text on my MacBook Air before this update. It is very frustrating and intermittent. Also, my mouse will occasionally freeze up and take a second or two to restart working. The slow text issue occurs irrespective of whether I am using the built-in keyboard, a plugged-in keyboard, or a bluetooth keyboard.

So far, I've reset NVRAM, reset the SMC and run disk utility to verify and repair the disk but none have fixed the issue. Anyone else experiencing the slow keyboard issue?

The Keyboard/Mouse are usually tied to a USB bus. The new firmware is ultra-aggressive to reduce battery consumption. Some of the 2011 MBAs will work fine with this update, but any pause in activity, seems to cause issues. You can check the Console logs and try and correlate your usage patterns of devices to the sleep/wake events and get a pretty good picture of what the new firmware is doing.

Ciao a tutti,

I have also problems with the 2.9.1firmware and my MacBook Air 13-inch Mid 2011.

After installing it, the FaceTime / iSight camera is always on. All the

Apps which require the camera (FaceTime / PhotoBoot / Skype) do not run because cannot acquire the lock to the camera.

NVRAM / SMC reset (done multiple times also) Do not help; installing the osx again and booting on the new system do not help.

The camera is active from the beginning of the boot-strap sequence till power-off.

Is there any official statement of Apple? I know those error only from the PC-word ... and it is really sad to find those kind of bugs in the Apple eco-system.

Software quality was one of the strength of the Apple brand and the reason why so many love this brand.

Hope to get a fix somewhen.

Have a great day.

Thank you for your answer. Just talking to Apple Support at this moment. I will report what they tell me after two month of waiting and ignoring. First they told me this would be a single problem of mine and is no common problem. Then i showed them this topic and about 12 other big topics with users all over the world having this problem too.

I also installed the latest EFI update. Now the facetime camera on Mid-2011 Macbook Air 11" will not work at all. Prior to this update, I had just finished a FaceTime meeting. All I get is that the camera is not found.

I have tried resetting the SMC, installing the OS from new, etc. Nothing has worked. I called Apple and they wanted me to send it in for repairs.

In , your post you mentioned updated firmware on Mac book air mid 2011 model that is 13 inch > and update was 2.9

But according to the article it is different .

About EFI and SMC firmware updates for Intel-based Mac computers - Apple Support

Same here:

Mid 2011 13-inch MBA dead after installing the EFI-Firmware-Update 2.9. Also tried SMC reset but the MBA is dead.

I Have this problem also. Completely dead. I attempted the key combination suggested by Ondray Wells Jr to no avail.

Any advice appreciated!

I just realised the fan is running quietly, so maybe not dead, just having a terrible dream.

I installed the EFI 2.9 update on both my Air's (13" & 11") booted back up fine.

However the APP STORE still indicates that I still need to download and install the update.

Same problem here! I tried to install the update 4 times..... Apple Store? Genius Bar? in Vienna? Dream on :-(

i"ve got the same issue (multiple "successful" installs but App Store still insisting I need to upgrade).

Ignoring it for now.

tried it 5 times inclusief manual install, no results. I think Apple screwed this one up. 👿😟

Same problem here with a 2011 MacBook Air 11".

Update shows as installed and in parallel it's shown as available for update.
