Second this: is there a MacOS sdk / library available providing programmatic access to ch347's i2c / spi / ... functionality?
There's libch347 + ch347_lib.h available for windows and various linux architectures, but not for macos in this repo.

I also have the same question, I installed the driver for macOS, but couldn't find the SDK that can be used.

I contacted WCH tech support and they provided the following macos demo app, as well as gave their kind permission to share it publicly. Haven't yet fully tried it out, but it looks it includes an arm64 library.

Thank you for sharing.
I tried using the DEMO software, and it seems to recognize the CH347, but the functionality doesn't appear to work properly.
