VR Desktop is currently in development. We are working on building a whole new version from the ground up, powered by our new Metal engine. This new version will support the HTC Vive, Vive Pro and upcoming Vive Pro Eye headsets. It will also feature eGPU support, and will require macOS Mojave.
We do not have a timeline for when we will be releasing VR Desktop. VR on macOS is still maturing, and we feel that there is still some work to be done by Valve before the experience is good enough for us to release a commercial product.
