Schmitz Apple has released [1]MacBook Air and MacBook Pro Update 1.0 for the models that were introduced in June: both 13- and 15-inch sizes of the MacBook Pro, the 15.4-inch MacBook Pro with Retina Display, and both the 11- and 13-inch versions of the MacBook Air. The slim documentation notes that this release 'fixes an issue that can lead to increased CPU power consumption, and it improves compatibility with some USB devices.' Requiring Mac OS X 10.7.4 Lion, the update should appear in Software Update for affected models, or you can download it directly from Apple's Support Web site.
