System requirements:

The Server is using NET9. The runtime is included in all releases from now on. Only the developer version requires the runtime to be installed via Download .NET (Linux, macOS, and Windows).
The Grasshopper plugin is targeting NET7. Therefore, it is only compatible with Rhino 8. If the β€œPRC Preview” tab is not showing up in Grasshopper, run the SetDotNetRuntime command in Rhino and select NETCore. Then restart Rhino.
PRC has been tested on Windows 11 and macOS 15 (M1 CPU or better). In general, all key features work on macOS, however some comfort features are missing (e.g. long-lasting certificates, autostarting the server…) Windows 7/8 and macOS 12 and below are not compatible with NET9. On macOS, PRC requires a M1 or newer CPU with ARM architecture. The developer version may work on Linux and Intel-based macOS devices.
