TL;DR
Homebrew 6.0.0 has been released, featuring a new tap trust 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 key security and performance improvements, including a new tap trust system, a faster internal JSON API, Linux sandboxing, and initial support for macOS 27.
The update’s most notable change is the implementation of a tap trust mechanism, which requires third-party taps to be explicitly trusted before their code is run, reducing security risks from malicious or compromised taps. The default internal JSON API has been upgraded to a faster, more efficient version, consolidating metadata downloads and reducing network load. Linux now benefits from sandboxing via Bubblewrap, aligning it with macOS security practices, and enhancing build and install security on Linux platforms.
Additionally, Homebrew has made defaults more user-friendly based on recent surveys, such as making ask mode the default for developers, prompting for confirmations before actions. The ‘brew bundle’ command has received multiple improvements, including parallel installation and support for npm, krew, and Windows’ winget, along with enhanced cleanup options. Performance optimizations across the board have resulted in faster startup times and upgrade processes. Support for macOS 27 (Golden Gate) has been added, with plans to phase out Intel support by September 2027. Security advisories addressed vulnerabilities related to HTTPS redirects, Git hooks, and installer package handling, reinforcing Homebrew’s security posture.
Security, Speed, and Platform Support Enhancements
The release of Homebrew 6.0.0 is significant because it strengthens security through the tap trust system, improves performance with a more efficient internal API, and extends compatibility to the upcoming macOS 27. These changes position Homebrew as a more secure and faster package manager, especially important for developers and users managing numerous packages across macOS and Linux platforms.

Major Updates Since Version 5.1.0
Since the previous release 5.1.0, Homebrew has focused on security, performance, and platform support. The introduction of tap trust addresses longstanding security concerns with third-party taps. The internal JSON API upgrade was tested in recent developer builds, now becoming the default. For more on how internal APIs can improve performance, see our deep dive. Linux sandboxing aligns Linux with macOS security practices, a move that reflects ongoing efforts to improve security across all supported platforms. Support for macOS 27 (Golden Gate) marks a new platform milestone, with phased support for Intel hardware planned through 2027. These developments follow Homebrew’s broader strategy to enhance security, speed, and platform compatibility.

Remaining Questions About Future Support and Adoption
It is not yet clear how widely the new tap trust system will be adopted by third-party taps or how quickly users will transition to the new features. Details about the full deprecation timeline for Intel support on macOS 27 and the impact on existing workflows remain to be seen. Additionally, the long-term security implications of the new sandboxing and API changes are still being evaluated.
Next Steps for Users and Developers Post-Release
Users are encouraged to upgrade to Homebrew 6.0.0 and familiarize themselves with the new tap trust system via the updated documentation. Developers should test their taps and formulae under the new trust model to ensure compatibility. Future updates are expected to refine the tap trust process, expand sandboxing features, and fully transition support away from Intel macOS hardware by September 2027. Monitoring Homebrew’s official channels will be key to staying informed about ongoing deprecations and platform support changes.
Key Questions
What is tap trust in Homebrew 6.0.0?
Tap trust is a new security mechanism requiring third-party taps to be explicitly trusted before their code is executed, reducing risks from malicious or compromised taps.
How does the internal JSON API improve performance?
The new API consolidates all metadata into a single download, enabling faster updates and less network traffic, which speeds up Homebrew operations.
What does support for macOS 27 mean for users?
Homebrew now offers initial support for macOS 27 (Golden Gate), with plans to phase out Intel support by September 2027, aligning with Apple’s hardware transition.
Are there security risks associated with these updates?
Homebrew has addressed several security vulnerabilities in this release, including HTTPS redirect bypasses and installer package issues, strengthening overall security.
When will Intel support be fully deprecated?
Support for Intel-based macOS will be phased out gradually, with no new bottles or CI support after September 2026, and complete removal by September 2027.
