Steam is required to run OpenVR applications, so install Steam and SteamVR. Once SteamVR is working properly with your headset, add OpenVR to the list of supported SDKs (see below to learn how to do this). If you require additional functionality beyond Unity’s built-in support, see the SteamVR asset store package.
OpenVR is supported on the followng platforms:
Unity OpenVR on a macOS requires the Metal graphics and 64bit application target, OpenGL is not supported.
OpenVR supports macOS 10.11.6 or later, but is optimized for macOS 10.13 High Sierra or later.
See documentation on OpenVR Controllers for input control mapping.
