Emergency When it all goes wrong

Code Red

One button when
it all goes wrong.

Code Red is always free. Locking down in an emergency should never be behind a paywall.

How Code Red works

How it behaves

Calm, honest and
on your side.

  • Everything happens on your Mac.

    Your apps, files, settings and network history stay on it. The only things that leave are public lookups you can see: package names and versions sent to OSV, public repository addresses to GitHub, and public wallet addresses to look up approvals.

  • Nothing changes without you.

    Every check is read-only. Fixes go into a review list, and nothing happens until you confirm.

  • Honest results.

    Mac Shield says what it checked, how much, and what it couldn’t. A clean result is reported as exactly that, not a promise.

  • Free to check.

    Every check is free; fixing things in a click is part of Mac Shield Pro. Code Red is always free.

  • Built for now.

    AI coding, crypto, clipboard hijackers, paste-this-command scams: the threats Mac users actually face today, not the ones from 2005.
