Apple has posted MacBook Air (Mid 2013) Software Update 1.0 (http://tinyurl.com/mtqupxc). It’s recommended for all MacBook Air (mid 2013) models.
The update — which requires Mac OS X 10.8.4 or higher — fixes an issue that in rare instances may cause an intermittent loss in wireless connectivity, an issue with Adobe Photoshop which may cause occasional screen flickering, and an issue which may cause audio volume to fluctuate during video playback.
