Apple today seeded the fourth beta of an upcoming tvOS 12.3 update to developers, one week seeding the third beta and a month after releasing tvOS 12.2).

Designed for the fourth and fifth-generation Apple TV models, the new tvOS 12.3 developer beta can be downloaded onto the Apple TV via a profile that's installed using Xcode. Apple has also released new 7.3 beta software for the third-generation Apple TV.


tvOS 12.3 brings a revamped TV app that was first shown off at Apple's March 25 services-focused event. The TV app is an updated version of the original TV app, providing access to TV shows, movies, sports, news, and more, along with a dedicated section for children's programming.

The TV app offers an updated interface with a fresh look and feel that's more modern. It still has the "Watch Now" section with the "Up Next" feature for keeping track of the TV shows and movies you're watching, and there's a new machine-learning based "For You" feature that surfaces content based on what you've previously watched.


There's a new "Channels" option built in to the app, which is a major part of Apple's new services push. Channels are subscription services that you can subscribe to and watch right in the TV app without having to swap over to a third-party app.

During the beta, you can subscribe to Showtime, Starz, Smithsonian, Tastemade, and EPIX, but additional Channels will be available when the new TV app launches.


In the future, Apple plans to add its new TV+ subscription service to the TV app, with TV+ offering all of Apple's original TV shows and movies. The TV app is available on the Apple TV and iOS devices so you can pick up whatever you're watching no matter which device you're on.

Is the picture quality better?
Doing some pretty quick totally unlegit eye tests, and apples seems much much less compressed. Good ol episode 3 of thrones as a sample. Yeah it’s definitely higher quality. Colors and blacks looks much better.

One funny thing, the sound seems INSANELY higher quality. I have a nice sound system and it’s night and day for how well the surround sound is coming through in apples vs hbo.

Not that it’s too impactful but buffering when you jump around the video seems to resolve much quicker as well.

Just to confirm I currently sub to cbs all access and hbo how through Apple iTunes. Do I need to sub through the new tv app directly instead ? or when I upgrade to the new TV app will these 2 apps automatically transition to the new format?
