Your Mac, explained
Scan your Mac
◇
A status you can understand
See scan progress, review concerns and understand coverage.
Illustrative interface. A scan summary reflects checked files, not a guarantee that your entire Mac is safe.
A little more peace of mind
Security, privacy and space.
Together.
Useful tools in one native macOS application, with decisions kept in your hands.
Private apps. Personal access.
MacLock is built in. Protect supported apps—Messages, Phone and FaceTime—with Touch ID or your Mac password. Switch away and let the app relock.
Find possible slowdowns.
Look beyond open windows. Review readable background processes, CPU and memory use, disk activity and startup registrations to understand what may be contributing.
Make room. Keep control.
Review eligible caches, exact duplicates and older installers. Choose what to clean up, see why it was suggested, and move confirmed selections to Trash.
Considered by design

Good questions
A few things
to know.
Clear expectations, from the beginning.
When can I download Sentinel Pro?
The public download is coming soon. Sentinel Pro is currently a development build. Visit the Downloads page for the latest availability; no release date or download package has been announced.
Does Sentinel continuously scan for malware?
Current malware scans run on demand. MacLock app privacy can keep running in the background, but that is separate from continuous malware monitoring.
Can it fix every reason a Mac is slow?
No. Performance Check highlights possible contributors from a short sample. It does not prove the cause of every slowdown or automatically terminate unfamiliar background services.
Does MacLock replace locking my Mac?
No. App privacy is a best-effort layer for supported apps. Notifications and other access paths can remain available, and account control or Force Quit can bypass it. Use the macOS screen lock for stronger protection.
Is it available for iPhone or Windows?
The current application is macOS-first. An iPhone or Windows edition is not available, and no release date has been announced for those platforms.
