🚀 Experimental Release for macOS Users

This release includes a macOS build for the first time!

We don't have access to a macOS environment, so we can't test it ourselves. If you're a macOS user and willing to help, please try it and report back through GitHub Issues or Discussions.

Thank you for your support!
