(Mid 2011) MacBook Air EFI Firmware Update 2.9.1 (Info/Download)
(Download page's bootrom typo corrected as of Aug. 1st)
"MacBook Air EFI Firmware Update 2.9.1 (4.3MB)
This update replaces EFI Firmware Update 2.9 and 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.

After the update, the EFI (Boot) ROM will be MBA41.0077.B11

System Requirements:
OS X 10.9.2 and later"

(The original D/L page had MBA41.0077.B11 under 'Requirements", a typo as that was the EFI version after installing the (pulled) v2.9 update. (Same version installed by 2.9.1 also.) The previous/pulled EFI 2.9 update requirements noted having EFI 0077.B00, .B08, .B0E or .B0F.)
Check MacBook Air forum for feedback on v2.9.1. (Early report from 13" 2011 MacBook Air owner said he updated OK. Boot rom MBA41.0077.B11 after EFI 2.9.1 update.)
