TL;DR
Homebrew 6.0.0 has been released, featuring a new tap trust security mechanism, a faster internal JSON API, Linux sandboxing, and initial support for macOS 27. These updates improve security, speed, and compatibility.
Homebrew has released version 6.0.0, introducing significant security enhancements, performance improvements, and platform support updates, including initial support for macOS 27 (Golden Gate).
The most notable change is the introduction of tap trust, a security feature requiring explicit trust for third-party taps to run code, reducing potential risks from malicious taps. Additionally, the internal JSON API is now the default, enabling faster updates and less network traffic. Linux users benefit from sandboxing via Bubblewrap, aligning Linux security with macOS. The release also includes improved defaults based on a user survey, such as making ask mode the default during installations and upgrades. Performance gains are evident across the board, with faster startup times, parallelized bottle fetching, and reduced Ruby library loading. Support for macOS 27 (Golden Gate) is now initial, with plans to phase out Intel support by September 2026. The update also contains security advisories addressing HTTPS redirect bypass, Git hook vulnerabilities, and installer package issues. These changes aim to enhance security, speed, and platform compatibility for users worldwide.
Enhanced Security and Platform Support Impact
The introduction of tap trust significantly improves the security posture of Homebrew by preventing untrusted third-party code from executing without explicit approval. Faster internal APIs and performance optimizations benefit users by reducing update times and system load, especially important for large-scale deployments. Linux sandboxing aligns Linux package management with macOS, improving security across platforms. Support for macOS 27 ensures compatibility with future Apple hardware and OS features, while the phased removal of Intel support marks a shift towards ARM-based architectures. Overall, these updates reflect Homebrew’s commitment to security, speed, and future-proofing, making it more reliable for users and developers.

Development Timeline and Prior Major Updates
Homebrew 6.0.0 follows previous releases that introduced various performance and security improvements, including the re-enabling of the internal JSON API in 5.0.0 and sandbox enhancements on macOS. The project has steadily increased security measures, such as deprecating insecure download strategies and addressing vulnerabilities in the installer and Git hooks. Support for macOS 27 (Golden Gate) begins with this release, as Apple shifts towards ARM architecture, with plans to drop Intel support entirely by September 2026. The move to initial support for macOS 27 aligns with Apple’s hardware transition timeline, and the ongoing migration from master to main branches reflects a broader effort to modernize development workflows.

Key Questions
What is tap trust, and how does it improve security?
Tap trust requires explicit approval before third-party taps can run code, reducing the risk of malicious or compromised taps executing arbitrary code on your machine.
When will Homebrew fully support macOS 27?
Initial support is available now, with full support expected as Apple releases more hardware and updates. Compatibility improvements will continue through 2024 and beyond.
Will Intel support be discontinued immediately?
No, Intel support for macOS will be phased out gradually, with full removal planned for September 2027. Until then, users can continue to use Intel-based systems.
What security vulnerabilities were addressed in this release?
Homebrew fixed issues related to HTTPS redirects, Git hook vulnerabilities, and installer package security, enhancing overall safety during downloads and installations.
