Founder & Lead Developer at CoreLock
I build Mac security software for a living. CoreLock started because I got frustrated with security tools that show you a wall of alerts with zero context — you'd see "threat detected" with no idea if it was actually dangerous or just a normal macOS process doing its job.
My background is in systems programming and macOS internals. I've spent years digging into LaunchAgents, XProtect, Gatekeeper, and the TCC privacy framework. I write about what I learn — partly to help other Mac users, partly because explaining things is how I make sure I actually understand them.
When I'm not writing code or blog posts, I'm probably reading Objective-See's latest research or arguing with someone online about whether Macs need antivirus.
Endpoint hardening, Gatekeeper, SIP, XProtect internals
AI-powered threat detection and process monitoring
Permission analysis, data flow tracking, camera/mic access
YARA rules, hash detection, network forensics on macOS
