But you can't distribute whatever you build legally as far as im aware. The apple sdks prevent you from shipping legally.

The only way atm is installing homebrew and using a gnu tool chain if I understand the license of the official sdks correctly?

My only experience with docker is headless in CI. I do have AMD. I'll have to look into this. Thanks

Emulating mac or using mac SDKs on non apple devices is against apple's bullshit license though.
