Every app on macOS carries a digital signature — and it’s more important than most people realize.
Here’s what signatures actually do:
✅ Identity — Confirms who created the app
✅ Integrity — Ensures the app hasn’t been modified or tampered with
✅ Trust — Helps macOS decide whether the software is safe to run
Apple’s code-signing system works alongside Gatekeeper and notarization to protect users from malicious software and unauthorized changes.
Why it matters for developers
• Prevents app tampering
• Builds user confidence
• Required for smoother app distribution on macOS
• Essential for enterprise and production apps
Security isn’t just about writing code — it’s about proving your code can be trusted.
