If you have a MacBook Air from mid-2011, you may have noticed intermittent issues where your laptop has a harder time waking up from sleep mode than it normally would have done, and when it does, the fans might loudly blast as if the whole laptop were on fire.

Although rare, these issues have been afflicting customers for at least the last couple of years. But it seems like Apple has finally figured out what’s wrong, as a new update today specifically for mid-2011 MacBook Air owners fixes the longstanding issues.

On Monday, Apple released the MacBook Air EFI Firmware Update 2.9 for Mid 2011 MacBook Air. Here’s the patch notes:

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 weighs in at a svelte 4.3 megabytes, and can be downloaded directly from Apple’s website, or through Software Update or the Mac App Store.
