Mac Finance App with Biometric Access -- 3

I need a native macOS desktop application that lets users grow or manage their money while relying solely on biometric authentication—Face ID or Touch ID—rather than traditional document verification checks. The flow should be as seamless as unlocking an iPhone: the moment the user launches the app, they authenticate with a quick face or fingerprint scan and immediately gain access to the main dashboard.

Key expectations
• Runs consistently on the latest macOS versions without additional libraries that require manual installation.
• Face ID or Touch ID must be the only gatekeeper; no passport, driver-license, or other paperwork screens anywhere in the journey.
• A clean, intuitive dashboard that displays balances and growth metrics (exact layout is open for your UX ideas).
• Full source code and a brief README explaining build steps so I can compile it myself if needed.

Timeline
I’d like a working build as soon as possible; please outline how quickly you can deliver incremental milestones and a final, stable release.

When you respond, focus on your direct macOS development experience—especially if you’ve integrated LocalAuthentication or similar biometric frameworks before. I’m interested in seeing how you have handled security, sandboxing, and notarization in previous projects.
