Sapphire is a new Rust-based package manager aimed at replacing Homebrew for macOS users. While still in early development, it challenges Homebrew's traditional package management model. Users appreciate its potential, though it currently lacks comprehensive features and poses some usability issues. The project creator is focused on improving bottle installs and addressing compatibility with existing Homebrew formulas. Feedback indicates both interest in the project and concerns over whether it can genuinely offer improvements over Homebrew, especially regarding documentation and broader package management functionality. The development environment encourages contributions and bug reports to enhance functionality moving forward.
