Apple today seeded the second beta of tvOS 10.2 to developers. This update comes two weeks after the last one. According to the release notes, there is a new feature that will allow you to scroll through content quicker with a big swipe on the trackpad. Other than that we’re not sure what’s new or fixed in this update.
To get this version developers can go to the Settings app and find it under software updates. If you aren’t on the beta yet you will need to connect the Apple TV to your computer and install it from there.
