Firmware Update For 2011 Mac Models Released

Mac OS X Lion

It is time for a firmware download if you purchased a Mac in 2011. Apple has recently issued four Extensible Firmware Interface (EFI) firmware updates, one for each Mac model released last year.

Mac mini EFI Firmware Update 1.6 is covering Mac mini models released last summer. MacBook Air EFI Firmware Update 2.4 is targeting the laptops that were released in mid-2011. iMac EFI Firmware Update 1.9 is is an update for desktop machines that debuted in May 2011. Lastly, MacBook Pro EFI Firmware Update 2.7 covers the laptops released in both early as well as late part of 2011.

All four updates have promised to improve stability in the targeted systems and fix several issues. Specifically, the release notes for each firmware update state that the download will improve the reliability of booting from the network and address an issue that can prevent High-bandwidth Digital Content Protection (HDCP) authentication after a reboot. The updates will also tackle an issue with boot device selection when you have got a hot-plugged USB storage device.

The updates are available from Mac OS X’s Software Update or on Apple’s Support website. The updates require Mac OS X 10.7.3.
