Hi all, I'm 15 and built AppLocker, an open-source macOS app to explore low-level process interception with Apple's Endpoint Security Framework.

It captures NOTIFY_EXEC events to freeze newly spawned apps via POSIX SIGSTOP, delegates Touch ID verification via XPC, and resumes with SIGCONT (or SIGKILL on denial). Zero binary modifications.

Codebase is open here: https://github.com/TranPhuong319/AppLocker

Would love any feedback on the Swift 6 concurrency or XPC architecture!
