You are using macOS on Intel x86_64. We do not provide support for this platform (as-of September 2026, announced August 2025). Apple have dropped Intel x86_64 support in macOS Golden Gate (27). GitHub Actions are dropping macOS Intel x86_64 runners in 2027. Homebrew is a non-profit project run entirely by volunteers, not employees. If the biggest companies in the world cannot support macOS Intel x86_64 any longer, sadly neither can we. Homebrew no longer builds bottles for this configuration. Existing bottles may still work, but updated formulae may build from source.

Due to capacity constraints, jobs targeting macOS arm64 runners may experience longer queue times.
