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
  • An experimental VPM package can be found at MisutaaAsriel/VRCHarmony which installs a packaged release of Harmony 2.4.1.
  • Unity appears to, in all testing,
    prefer
    the package's copy of Harmony over the version included by the VRC Base SDK.
  • This package may also be installed using the following VPM repository: Dreemurrs-Repository
  • VRChat may use the DLL provided from this repository if need be, or take over the package if they so wish.
    — It is currently built off of the
    Release
    target of Harmony, at the solution level, with
    .NET Framework 4.5.2
    using GitHub Actions
Note
  • Building
    Lib.Harmony
    against the
    DebugFat
    target at the project level, or building it for
    Release
    against
    net452
    at the solution level
    creates a
    successful drop in replacement.
  • The release builds when
    built at the .NET project level
    or
    downloaded from the main Harmony repository
    currently
    output a mangled DLL that Unity Burst is incompatible with.
  • A bug report is open on this here: pardeike/Harmony/issues/728
  • 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.
