For macOS 14 and later

Mac security that explains itself

Your Mac is running things you never installed. Most tools hand you a list of file paths and leave you to work out which ones matter. Shadow Sentinel finds them, then tells you exactly what each one is.

The difference

Every scanner shows you a list. Then what?

Signature matching catches known malware and shrugs at everything else. What's left is a wall of technical entries, and the only honest answer most tools can give you is "unknown". That's where Shadow Sentinel starts.

What other tools tell you

com.updater.helper.plist
~/Library/LaunchAgents/
Status: unsigned · runs at login

Technically accurate and completely unhelpful. Is that a printer driver you installed two years ago, or is it reading your keystrokes? Delete the wrong one and you break something you needed.

What Shadow Sentinel tells you

com.updater.helper.plist
~/Library/LaunchAgents/
Status: unsigned · runs at login
Malicious · high confidence

Runs a script that downloads and executes remote code at every login. Legitimate software never does this. Recommended: quarantine.

Protect

Find it, understand it, deal with it

Signature matching and code-signature verification handle what rules can decide. The analyst handles everything in between — which, on a real Mac, is most of it.

Full-system malware scan

Walks 57 locations where Mac malware actually lives, inspecting real executables rather than trusting file extensions.

Startup & persistence

Every LaunchAgent and LaunchDaemon — where malware hides to survive a reboot — checked against known families.

Live monitor

Watches those folders in real time. The moment something installs itself at startup, you know — and you know what it is.

Ask Sentinel

Ask about anything on your Mac in plain language. It answers using what it actually found on your machine, not generic advice.

Process inspector

Flags running processes with malware tells: executing from temp folders, hidden directories, unsigned binaries in odd places.

Browser hygiene

Audits extensions across Chrome, Brave, Edge, Arc, Firefox and Safari, and catches hijacked homepage and search settings.

The one nobody answers

What is actually inside “System Data”?

Every Mac owner has opened Storage settings, found 150 GB labelled System Data, and been told nothing else. Apple won't break it down. Neither will any cleaner we've found.

Shadow Sentinel does. It identifies each thing inside it by name, tells you what created it, whether it's safe to remove, and what breaks if you do. Most of it turns out to be Time Machine snapshots, a sleep image the size of your RAM, and developer caches nobody knew were there.

Clean

Reclaim the space, without the guesswork

Everything Shadow Sentinel removes goes to the Trash. Nothing is ever permanently deleted, so a mistake is always one click from undone.

Cache & log cleaner

What each app has quietly accumulated, sized and sorted, so you decide what goes rather than trusting a progress bar.

App leftovers

Support files, preferences and caches belonging to apps you deleted months ago and macOS never cleaned up.

Large & duplicate files

Anything over 100 MB, plus hash-verified duplicates — identical content, not just identical names.

Complete uninstaller

Drag in any app and it finds everything that app owns across a dozen system locations, then removes all of it at once.

Built to be trusted

A security app should hold itself to a higher standard

Nothing is ever deleted

Every removal goes to the Trash. If Shadow Sentinel gets something wrong, you restore it in one click.

Your files stay yours

AI analysis sends metadata only — names, paths, signature status. Never the contents of your files.

Notarized by Apple

Signed with a Developer ID and verified by Apple, so macOS opens it without warnings.

It complements macOS

Works alongside XProtect and Gatekeeper. It never disables or replaces your Mac's built-in protection.
