Developers can now offer app bundles up to 4 GB in size for Apple TV owners. Until Apple announced the change on its developer site, initial app downloads were limited to 200 MB. The change in policy means tvOS app binaries are now covered under the same 4 GB limit allowed for iOS apps. So what will this really mean to Apple TV fans who use the App Store?
By default, the fourth-generation Apple TV automatically installs updates to tvOS and any installed apps. Shortly after Apple releases a system update or an app developer's changes are approved by the App Store, the new versions roll out. Some users aren't a fan of this feature, as it can bring unwelcome changes to familiar apps. Others like to see if a firmware update is reported to cause any problems before they install it on their device. Here's where switching to manual updates on the Apple TV comes into play.
Single sign-on makes it easy to enjoy content from many different sources on the Apple TV without entering account information into every app. Participating TV providers automatically log in to every supported app requiring authentication. Single sign-on can also be configured on the iPhone for seamless viewing. Once the feature is set up on the Apple TV, a list of authenticated apps that are available can be accessed.
Apple introduced a more theatrical option for Apple TV owners in tvOS 10 called Dark Mode. Instead of the normal light grey interface, this provides a different flavor for night viewing or those who prefer this look. The color change affects tvOS throughout the system menus and within particular apps. Currently there is no way to make Dark Mode switch on automatically at sunset or a specific time.
Noticed the home button on your Apple TV doesn't go to home anymore? Once updated to tvOS 10.1, the default behavior of the home button on Siri Remote changes automatically. Instead of returning to the home screen, the home button opens the TV app. Apple introduced the TV app to help unify all of the different streaming services and media libraries in one place.
