PlayStation 4 system software

The PlayStation 4 system software is the updatable firmware and operating system of the PlayStation 4.

Technology
The native operating system of the PlayStation 4 is Orbis OS, which is a fork of FreeBSD version 9.0 which was released on 12 January 2012. The PlayStation 4 features two graphics APIs, a low level API named GNM and a high level API named GNMX. Sony's own PlayStation Shader Language (PSSL) was introduced on the PlayStation 4.

Other components included are Cairo, jQuery, Mono, and WebKit.

The Software Development Kit is based on LLVM and Clang.

Graphical shell
The PlayStation 4 uses the PlayStation Dynamic Menu as its graphical shell.

The process of updating is almost identical to that of the PlayStation Portable, PlayStation 3, and PlayStation Vita. The software may be updated by downloading the update directly on the PlayStation 4, downloading it from the user's local Official PlayStation website to a PC and using a USB storage device to transfer it to the PlayStation 4, or installing the update from game discs containing update data.
