SteamVR is a virtual reality hardware and software platform developed by Valve, with a focus on allowing “room-scale” experiences using positional tracking base stations, as opposed to those requiring the player to stay in a singular location.
Valve explained in a small update via the official Steam Community :
“SteamVR has ended macOS support so our team can focus on Windows and Linux. We recommend that macOS users continue to opt into the SteamVR [macos] branches for access to legacy builds. Users can opt into a branch by right-clicking on SteamVR in Steam, and selecting Properties… -> Betas.”
