The 2009 Aluminum Keyboard Firmware Update 1.0 improves battery performance of the 2009 aluminum Apple Wireless Keyboard when used in combination with other Bluetooth devices (such as Apple Magic Mouse and some Bluetooth headsets).

Quit all open applications, then download the update.

  1. The downloader will place the disk image with an installer in your Downloads folder or in the location specified in the General tab under Safari > Preferences.
  2. If you downloaded the disk image via Safari, Safari will notify you that an application is in the image.  Click OK to continue.
  3. If "Open safe files after downloading" is enabled in Safari preferences, the disk image file will mount by itself.  If that preference is not enabled in Safari, double-click the disk image to mount it.
