Yesterday Apple released software version 4.2.1 for the popular second generation Apple TV. The device, which had been experiencing somewhat widespread issues following the 4.2 update, should now operate more reliably. Arriving less than two weeks after the release of 4.2, Apple clearly listened to user feedback and expedited development of the patch. According to the support document accompanying the release, the following issues have been addressed:
TV compatibility:
Addresses issues that may cause the screen to flicker or display incorrect color on some older TVs.
Wake from sleep:
Addresses an issue where Apple TV may not wake up from sleep.
Audio:
Addresses an issue where audio may not be heard on some TV models after switching from another input.
Stability and performance:
Apple TV Software Update 4.2.1 includes stability and performance fixes for Apple TV.
The bug affecting the greatest number of Apple TV owners was intermittent screen flickering. Last week this issue was traced to older HDTVs attempting to convert the Apple TV’s 720p output to 1080i. Early feedback seems to indicate the update resolves this problem. Apple TV users can download the update from their devices directly. Using the Apple Remote, simply navigate to: Settings > General > Update Software.
