Yesterday, Apple released the seventh beta version of its operating systems. As a rule, you can find something new in the beta versions of iOS 11 and macOS High Sierra, and watchOS 4 and tvOS 11 do not change much from assembly to assembly. But you can find a lot if you look good. For example, the mention of a new device model in the firmware.
Information caught the eye of the developer Guillermo Rambo. He found a mention of HDR support for the device, code-named "J105a". Earlier, Bloomberg reported the development of Apple TV with support for 4K-resolution with a similar code name.
Previously, the same developer found a mention of the future Apple TV console in the firmware for the smart HomePod column. He does not stop there and continues to look for information about devices that have not yet been announced.
