Check your Mac for malware by listing what can start, connect and read your files
xinc3s shared a Claude Code prompt that checks a whole Mac in about 5 minutes. Instead of matching known-bad files like antivirus does, it asks one question: what on this machine can start by itself, talk to the internet or read your files.

What they did
xinc3s shared a Claude Code prompt that checks a whole Mac in about 5 minutes. Instead of matching known-bad files like antivirus does, it asks one question: what on this machine can start by itself, talk to the internet or read your files.
Result (as claimed)
A short list of everything with autostart, network or file access to review.
Tools they used
Cost: Pricing depends on the tools you pick; check each official pricing page.
Set it up
Pick a contained repo or task
Start on a branch or side project where mistakes are cheap.
Install and configure
Set up Claude Code. Read what it can run on your machine and limit permissions where possible.
Run it on a real task
Give it a well-scoped issue and let it work. Review the diff like any pull request.
Add guardrails
Keep tests and CI in the loop, and never let an agent push to main or touch production secrets unattended.
Copy the full setup prompt
Paste into your agent and it will walk you through the setup, asking before anything that sends, posts or spends.
