"This update fixes several issues to impr..."

This update fixes several issues to improve the stability of MacBook Air (mid 2011) computers and is recommended for all users.

This update includes fixes delivered in MacBook Air EFI Firmware Update 2.1 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 MacBook Air (mid 2011) models.

The MacBook Air EFI Update will update the EFI firmware on your notebook computer. Your computer's power cord must be connected and plugged into a working power source. When your MacBook Air restarts, a gray screen will appear with a status bar to indicate the progress of the update. It will take several minutes for the update to complete. Do not disturb or shut off the power on your MacBook Air during this update.

Boot ROM or SMC Version Information: After MacBook Air update has successfully completed, your Boot ROM Version will be MBA41.88Z.0077.B0E.1110141154

Before installing version 2.2 of Apple MacBook Air EFI Firmware Update for Mac OS make sure this is the latest version available and that it works with your current operating system and device model. If the driver contains release notes ("readme" files) proceed with reading them first. Second recommended step is creating a restore point to help you later on in case you install the wrong device driver. Note that some drivers will work instantly after installing them, but others will require a system restart in order to function properly.

As an alternative, you can simplify the process of installing the latest versions for your drivers by using a program to scan all your drivers and compare them with the latest available versions from the manufacturers. We recommend Driver Scanner from Uniblue for such a task. Download it and run a free driver scan here.
