VisionOS

visionOS is an embedded operating system created specifically for Apple Vision Pro. It is based on RTKit, a real time operating system based on XNU microkernel developed internally by Apple.

An internal build of recoveryOS was available to download on 15th June of 2023, allowing some analysts to start digging into firmware. At the moment, it is not certain about what details are included in the firmware. The internal name seems to be Borealis.
