Apple today seeded the first beta of an upcoming tvOS 14.3 update to developers for testing purposes, with the beta available a week after the tvOS 14.2 release.

Designed for the fourth and fifth-generation Apple TV models, the tvOS 14.2 developer beta can be downloaded onto the ‌‌‌‌‌‌Apple TV‌‌‌‌‌‌ via a profile that's installed using Xcode.

Other than new releases, tvOS updates are often minor in scale, focusing on under-the-hood bug fixes and improvements rather than major outward-facing changes. There's no word yet on what's included in tvOS 14.3 update, but we'll update this article should anything new be found.

Though we don't often know what's new in tvOS during the beta testing process, we let MacRumors readers know when new updates are available so those who are developers can download it upon release.

Apple's tvOS 14 update brought expanded Picture in Picture support, new HomeKit integration with HomeKit Secure Video cameras, support for multiple Apple Arcade profiles, and more, with details available in our tvOS 14 roundup.

Unfortunately tvOS 14.3 beta still does not support “HLG HDR” format (iPhone 12 recorded videos). All played in SDR.

Just updated my Apple TV 4K to the new 14.3 beta and it looks like the issue with the bluetooth device disconnecting when powering off has been fixed. Thanks Apple.
