Apple Releases MacBook Air Software Update to Fix Photoshop Screen Flickering and Wi-Fi Connection Issues
This update is recommended for MacBook Air (mid 2013) models.News of the screen flickering issue emerged shortly after the release of the 2013 MacBook Air, when users began noticing display flickering when using Photoshop, especially when accessing the app's larger brush tools. An Adobe representative noted that it was likely a driver or GPU issue and last week, a tipster reported that OS X 10.8.5 fixed the issue, suggesting that Apple had found a solution.
This update 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.
New MacBook Air owners also experienced Wi-Fi connection issues, prompting Apple to begin looking for a solution in mid-June after issuing an order for Apple Geniuses to "capture" MacBook Airs experiencing connectivity problems.
Apple's June 2013 MacBook Airs use the newest 802.11ac Wi-Fi standard, which is designed to offer faster connectivity and bandwidth.
The update can be downloaded via the software update page or through the software update tool in the Mac App Store.
