I'm trying to build this on macos x86 but fails with:

By default, when we detect we're on OSX, we try to build an M1 binary as well. If you run the suggested rustup target add aarch64-apple-darwin that should work and you shouldn't have issues.

Hmmm, but my machine is not an M1... I'll try

That worked, thx!
