    this incredibly annoying error keeps popping up when playing in the editor, it doesn't seem to actually effect anything, but it really shouldn't be there

    using Unity 2021.2.16f1 on Apple Silicon

    packages
    Mock HMD XR Plugin 1.3.0-preview.1
    XR Interaction Toolkit 2.0.2
    XR Plugin Management 4.2.1

    DllNotFoundException: UnityMockHMD assembly:<unknown assembly> type:<unknown type> member:(null)

    finally figured this one out

    you need to disable "Initialize XR on startup" under XR Plug-in Management within the desktop settings

    If you want to use Mock HMD with apple silicon in order to take stereo paths: it shipped recently as version `1.3.1-preview.1` - you can update to it in package manager. Do note that single-pass instanced is not yet supported on mac hardware so you'll need to switch to multi-pass rendering in the XR Plug-in settings.
