Apple has released Apple TV Software Update 4.2.1, the latest software update for its second-generation set-top box. According to Apple’s Apple TV software update support page, the new software addresses issues “that may cause the screen to flicker or display incorrect color on some older TVs,” an issue “where Apple TV may not wake up from sleep,” and an issue “where audio may not be heard on some TV models after switching from another input,” and also offers other unspecified stability and performance fixes.
Notably, a number of second-generation Apple TV owners had complained of flickering issues following the release of the 4.2 update. Apple TV Software Update 4.2.1 is available now via the device’s software update feature.
