The Harmony package, used by Udon Sharp, and a handful of third-party community plugins for runtime patching in the editor, has been updated to officially support
ARM64
on all platforms (Windows, Linux, and yes, Mac).
This will correct any in-editor issues when running the Unity Editor on these platforms. Whilst VRChat itself may only support PC & Android, the Unity Editor is a cross-platform utility, and there are a variety of folks with ARM-equipped machines who use such hardware for primary development, and therefor experience issues with the editor without patching.
With the advent of full iOS support on the horizon, this may further increase the # of Mac-based content creators.
Please update the provided package.
Addendum
Note
  • The
    release builds when built alone or downloaded from the main project currently output a mangled DLL that Unity Burst is incompatible with.
    However, building
    Lib.Harmony
    against the
    DebugFat
    target or building it for Release against
    net452
    at the solution level
    creates a successful drop in replacement.
  • A bug report is open on this here
  • For further reference, the original copy of Harmony is built against .NET 4.5.0, which is no longer a valid target. 4.5.2 was chosen as its nearest replacement.
