Late Wednesday, Apple released EFI firmware updates for both its 2011 MacBook Pro and MacBook Air notebooks. The updates, which weigh in at a 4.1 megabyte download and a 4 megabyte download, respectively, fix several issues to improve the stability of Apple’s mid-2011notebooks.
The update includes fixes that enhance the stability of Lion Recovery from an Internet connection, and resolve issues with Apple Thunderbolt Display compatibility and Thunderbolt Target Disk Mode performance on Apple’s mid-2011 notebook models.
As always, the updates can be located, downloaded and installed via Mac OS X’s built-in Software Update feature.
The updates require an Intel-based mid-2011 MacBook Pro or MacBook Air notebook and Mac OS X 10.7.2 or later to install and run.
If you’ve installed the firmware updates and have any feedback to offer, please let us know in the comments.

It didn’t install for some reason :/ I tried to install it yesterday, but after the computer wanted to reboot, it kept going on and off all the time, and while the grey bar was trying to load the computer was shut off again. So when it finally did reboot I thought everything was installed, but now it tells me it is not. Help?
I have the same problem. It beeps and shuts off, and reboot, shuts off and reboots, shuts off and reboot, and then the apple logo appears and while it’s loading, it shuts off again. Then it just reboots normally. it never really got installed. I have Mac OS X v10.7.2. I am so annoy by this!
Same here
Do the update while the power is plugged in to your MacBook. Worked for me. Most likely a setting from Apple to ensure you don’t brick your MacBook because of a drained battery.
