According to AppleInsider, Apple is using their AppleSeed testing program for a new update to the 2013 802.11ac MacBook Airs released a few weeks ago. Some users are reporting that they are having problems of their computers randomly disconnecting and reconnecting to their wifi base stations, even if they are not 802.11ac.
Apple is reportedly seeding this update to select customers to see if it fixes the problems people are having. Reportedly the update isn’t available for download yet for those customers, but if it fixes the issues when the update arrives, then we’ll probably see it be publicly available for all users sometime soon, either through this “Wifi Update” package or Mountain Lion version 10.8.5, which Apple is also testing with developers.
For those of you having problems with a new MacBook Air, hopefully this update comes out soon to you.
