ps: add sudo xattr -rd com.apple.quarantine on post-install (homebrew formula)
example:

class MildstackDesktop < Formula
  # ...
  
  post_install do
    # Auto remove quarantine
    system "xattr", "-rd", "com.apple.quarantine", 
           "#{appdir}/MildStack Desktop.app"
    
    puts "\n✅ MildStack Desktop sucessful installation!"
  end
end
