Four separate firmware downloads for multiple computers, all with the same purpose

Apple this week updated the firmware of most of its Macintosh models, including the iMac, the MacBook Air, the MacBook Pro, and the Mac mini, to patch a number of issues that affected all systems in a similar manner.

With the exception of the Mac Pro, which many believe will get discontinued soon, the entire Macintosh family of computers has received a firmware update that “improves the reliability of booting from the network, addresses an issue that can prevent HDCP authentication after a reboot, and resolves an issue with boot device selection when a USB storage device is hot-plugged.”

In the case of each computer model, Apple separately touts the firmware update as being able to fix “several issues to improve the stability of […] computers and is recommended for all users.”

Systems targeted by these four firmware updates are all 2011 models — MacBook Pro (Early 2011) and MacBook Pro (Late 2011); MacBook Air (Mid 2011); iMac (Early 2011); Mac mini (Mid 2011).

Firmware updates such as these update the firmware originally shipped from the factory.

For Intel-based Macs, some firmware updates may not be displayed automatically using Software Update. Should they not appear in Software Update, they will have to be manually downloaded from the Apple Downloads site (or from Softpedia, using the links below).

“If you are unsure whether your computer needs a particular update, simply download and open the update installer. The installer will alert you if the firmware update is already installed or not needed,” Apple states.

All firmware is to be applied on OS X 10.7.3 (Lion). Supported languages include Deutsch, English, Français, Español, Italiano, Nederlands, Dansk, Norsk Bokmål, Polski, Português, Português Brasileiro, Pусский, Suomi, Svensk, Chinese, Japanese and Korean. All packages are in the 3.7 - 4.1MB range.
