Some owners of the 2013 MacBook Air are experiencing problems with uncontrollable volume fluctuations, according to posts
on Apple's support forums. The issue typically manifests in first- and third-party apps playing video, including Apple's own QuickTime. Although Apple has yet to provide a fix, third-party sound enhancement apps can potentially keep audio manageable.
The new Air has been beset by several technical issues. These include flaky Wi-Fi connections
and flickering graphics in Photoshop
. Yesterday's AirPort Utility update
may solve Wi-Fi difficulties.
