Valve has ended Mac support for SteamVR so its team can focus on Windows and Linux.
In case you’re not familiar with it, OpenVR is a software development kit and application programming interface developed by Valve for supporting the SteamVR and other virtual reality headset devices. The SteamVR platform uses it as the default application programming interface and runtime.
Mac users can continue to use the latest versions of SteamVR by installing Windows as a secondary OS. According to Valve’s Hardware Survey, just under 4% of Steam users are using macOS, with over 95% using Microsoft’s Windows. Given that just over 1% own a VR headset at all, the gang at the UploadVR website say “it’s easy to see just how niche VR on macOS likely was.”
