For years, Soundflower has been a go-to solution for routing audio internally on macOS. However, with newer macOS updates and the need for improved compatibility and features, many users are seeking alternatives. Whether for recording system audio, live streaming, or routing sound between applications, better solutions are available in 2025.
Why Look for an Alternative?
Soundflower, while once a powerful tool, has had its drawbacks:
- Lack of official support: It is no longer actively maintained.
- Compatibility issues: Some macOS updates have broken or required workarounds for installation.
- Security concerns: Being an unsigned kernel extension, macOS often blocks its installation.
Fortunately, many alternatives now offer a smoother experience with better performance on modern macOS versions.
