macOS / build and test (macos-26-intel)
The following taps are not trusted: aws/tap azure/bicep Homebrew will ignore formulae, casks and commands from these taps when `HOMEBREW_REQUIRE_TAP_TRUST` is set. This will become the default in Homebrew 6.0.0 or 5.2.0, whichever comes first. Enable trust checks now with: export HOMEBREW_REQUIRE_TAP_TRUST=1 Trust specific formulae, casks or commands with: brew trust --formula <user>/<tap>/<formula> brew trust --cask <user>/<tap>/<cask> brew trust --command <user>/<tap>/<command> or trust installed formulae from these taps with: brew trust --formula azure/bicep/bicep You can trust all formulae, casks and commands from these taps with: brew trust aws/tap azure/bicep Prefer trusting only the specific formulae, casks or commands you need. Untap them with: brew untap aws/tap azure/bicep To keep allowing them by default during the transition: export HOMEBREW_NO_REQUIRE_TAP_TRUST=1 This is not recommended and will be removed in a later release.
