The following taps are not trusted: aws/aws Homebrew is currently ignoring formulae, casks and commands from these taps because tap trust is required. Prefer trusting only the specific formulae, casks or commands you need. Trust installed casks from these taps with: brew trust --cask aws/aws/amazon-ssm-agent aws/aws/ec2-instance-connect aws/aws/ec2-macos-init aws/aws/ec2-macos-system-monitor aws/aws/ec2-macos-utils Trust other specific formulae and commands with: brew trust --formula <user>/<tap>/<formula> 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/aws Untap them with: brew untap aws/aws For more information, see: https://docs.brew.sh/Tap-Trust
