Apple has shipped software for its new generation aluminium keyboards, Keyboard Software Update 1.1.
The company advises users to install the software in order to use the keyboard and take advantage of its special features. The update is a 32.1MB download.
Apple has issued little information as to the content of the update, though a recent report on ReelSmart claims that the keyboard mapping on the new input devices did not appear to be working correctly. It's feasible the patch is intended to address this, should that report be true.
