In this article I will explain versions of Apple TV as it comes very confusing to some users.
The Apple TV device runs the operating system called iOS.
On this operating system runs Apple TV software system.
Imagine that it is like Microsoft Windows running Windows Media Player.
That’s why Apple TV 2G comes with two “version” numbers.
Software Version – which is also called firmware version.
We can find it under Settings > General > About and see “Software Version”
System Version – which is the version of iOS.
We can find it under Settings > General > About by clicking once on “Software Version”
For example Apple TV Software Version 4.2 runs on iOS version 4.3
