Apple released a software update for owners of the new 27-inch LED Cinema Displays. The update includes modifications to two OS X system preference panes, which enable brightness and audio features on the new displays.

This update requires OS X 10.6.4 to install. It is also relatively large for a standard display update (75MB download, with around 250MB of replaced system components), but upon looking at the install package, the update not only replaces the specified system preference panes, but also includes new releases of graphics drivers, frameworks, and other video and audio components to update compatibility with the Cinema displays. The update does not install any firmware to the display itself, even though the display will need to be attached when you run the updater.

To install the update, you will need to follow the instructions posted in this Apple Knowledgebase Document (reiterated below):

  1. Connect your Mac to your LED Cinema Display (27-inch).
