Macbook Air update fixes flickering screen and WiFi

---

If you've been experiencing unstable WiFi as well as flickers while Photoshopping on your new mid-year MacBook Air, Apple's got you covered. The tech giant reports that the patch addresses the aforementioned issues cropping up in "rare instances," as well as a bug that causes audio levels to jump around during video playback. The software 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.
