Valve has announced that SteamVR will drop support for the macOS platform so that development teams can focus on Windows and Linux support. SteamVR users running macOS who wish to continue using SteamVR will need to opt-in for legacy macOS builds from the "Beta" tab under SteamVR properties. This measure will probably stop functioning relatively quickly as new hardware and software changes appear. This move doesn't come as much of a surprise as the macOS platform isn't known for its VR activity, in the long-term macOS users will have to migrate to an alternate operating system or dual boot if they wish to continue accessing SteamVR.
