The following taps are not trusted: aws/tap Homebrew is currently ignoring formulae, casks and commands from these taps because tap trust is required. Untap them with: brew untap aws/tap Trust specific formulae, casks and commands with: brew trust --formula <user>/<tap>/<formula> brew trust --cask <user>/<tap>/<cask> brew trust --command <user>/<tap>/<command> Whole-tap trust is broader and includes all current and future formulae, casks and commands from the listed taps. Trust whole taps with: brew trust aws/tap To disable trust checks: export HOMEBREW_NO_REQUIRE_TAP_TRUST=1 This is not recommended and will be removed in a later release.

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. You will have better luck with MacPorts which still supports macOS Intel x86_64: https://www.macports.org
