Is Mac ARM64 supported?

[GuruGurra]

"MIDI support on both Windows (64-bit or 32-bit) and Mac OS X (64-bit) ". Does that include support for both X64 and ARM64 on OSX?

When running my app, built for arm64, I get the following error:

Exception while creating default input device: System.DllNotFoundException: Unable to load shared library 'rtmidi' or one of its dependencies. ...tried librtmidi.dylib' (mach-o file, but is an incompatible architecture (have 'x86_64', need 'arm64e' or 'arm64'))...

If I understand it correctly, what is needed is a version of the rtmidi.dylib built for arm64 architecture. How can I get such a file?
