With any luck, this will work.
- This update is recommended for MacBook Air (Mid 2011) models. This update addresses an issue where systems may take longer to wake from sleep than expected and fixes a rare issue that may cause fans to run at full speed after waking from sleep.
The update can be directly downloaded from Apple’s web site or located and installed via OS X’s Software update feature.
If you’ve tried the new firmware and have any feedback to offer, please let us know in the comments.
Some users have been reporting problems with the EFI update. In some cases, users’ computers would not restart after installation. In others the update would appear to install, but when the laptop restarts, the update is not applied, appears as installed in the App Store app, and STILL shows up as needing to be installed. Multiple attempts at the install simply add an identical entry to the list of installed software with no changes to the computers firmware.
I personally ran into the latter situation. My MacBook Air is still working fine, but the firmware did not update. People are also having problems with the separate installer downloaded from Apple’s web site. We highly recommend that if you have not updated yet that you hold off until more data can be collected and Apple possibly deploys an update to the update.
