Execute macOS code signing with Developer ID and hardened runtime requirements

Instructions available. Your AI can read the instructions. Execution depends on the setup they require.

Account requirements not reviewed. Check the skill instructions before use; ahel provides instructions and does not run this skill.

Add ahel to your AI once: Claude, ChatGPT, Cursor, Claude Code or Codex. Then ask it to use this.

Then ask your AI: use the macos-codesign-workflow skill

What this skill tells your AI

Signing Commands

# Sign app bundle with hardened runtime
codesign --force --options runtime --timestamp \
    --entitlements MyApp.entitlements \
    --sign "Developer ID Application: Company Name (TEAMID)" \
    MyApp.app

# Sign nested components first
find MyApp.app -name "*.dylib" -o -name "*.framework" | \
    xargs -I {} codesign --force --options runtime --timestamp \
    --sign "Developer ID Application: Company Name (TEAMID)" {}

# Verify signature
