CleanMyMac vs CoreLock: Cleanup Tool or Security Tool?

CleanMyMac, from MacPaw, is a well-known Mac utility. This post is not a review of it. Its features and pricing change, and the only reliable source for them is MacPaw's own website. What this post covers is what CoreLock is, what it is not, and how to decide whether you need a cleanup tool, a security tool, or both.

Two different jobs

Mac optimizer apps in general focus on housekeeping: finding junk files, clearing caches, uninstalling apps along with their leftover files, and running maintenance routines. Some also include a basic malware scan. CleanMyMac is a well-known example of this category.

CoreLock is a security scanner, not a cleanup tool. It has an optional clean-up, off by default, that deletes day-old temp files and trashes a few app caches over size limits. It has no app uninstaller or system-junk cleanup. It is built to answer the question: what is actually happening on my Mac right now?

What CoreLock does

Six-check scan. CoreLock checks running apps, network, app permissions, login and background items, AI agents and your Downloads folder. The results feed a Security Score from 0 to 100. A check that can't run is shown as not checked, never as passed. Scans run in the background every 15 minutes by default.

TCC permission audit. macOS has a permission system called TCC (Transparency, Consent, and Control) that governs which apps can access your camera, microphone, screen recording, full disk access, and more. With Full Disk Access, CoreLock's Privacy screen lists these permissions, such as camera, microphone, contacts, photos, files and folders, Screen Recording, Accessibility, Full Disk Access and Input Monitoring. The scan flags sensitive permissions left behind by apps you removed.

Running apps check. CoreLock looks at the 100 busiest processes. It flags known-bad tools, such as crypto miners, and risky command lines, such as reverse shells, download-and-run and encoded commands.

Processes screen. It lists the 100 busiest processes, sorted by CPU, with friendly names for common ones. You can stop your own processes.

Code signature verification. Every legitimate Mac app should be signed by its developer and notarized by Apple. On demand, CoreLock's Apps screen checks the code signature and Gatekeeper and notarization status of apps at the top level of /Applications and ~/Applications. It flags unsigned apps and broken or expired signatures. It doesn't detect revoked certificates.

Network. The Network screen lists your apps' open connections by IP address and port. It shows addresses, not hostnames, and it can't see processes owned by root. The scan also lists services listening for connections from other devices, and Shields can turn on the macOS firewall and Stealth mode.

Downloads check. Files in Downloads are checked against a built-in list of known-malware SHA-256 hashes and CoreLock's malware-signature (YARA) rules. A signature match is a reason to look at the file, not proof it's harmful, and nothing is quarantined automatically. Scripts and Windows installers also get simple heuristic scoring. It doesn't look inside Mac app bundles.

Pricing. CoreLock Free costs $0 and includes the full six-check scan, with unlimited scans. CoreLock Pro is $9.99 per month ($50/year, or $200 once for Lifetime). It removes the daily cap on AI scan reviews and adds a Full file scan of more folders, cloud sync, and priority support.

What CoreLock covers

CoreLock's clean-up is limited and off by default, and it has no app uninstaller or system-junk cleanup. If that is what you need, look at a Mac optimizer and read its vendor's own pages for what it offers.

The free alternative question

If you landed here searching for a free alternative, here is what CoreLock's free tier gives you: the full six-check scan with unlimited scans, and 3 AI scan reviews a day if you sign in and turn AI explanations on. You get the same scan, the same permission list, and the same process view as Pro. The Pro tier removes the AI cap and adds a Full file scan and cloud sync, but the free version covers the main checks. It does not clean junk files or uninstall apps.

When a Mac optimizer may be what you want

An optimizer is the right category when your goal is housekeeping: reclaiming storage, uninstalling apps cleanly, or running maintenance tasks from one interface. macOS also has built-in storage management in System Settings > General > Storage, and free utilities exist for individual jobs, so compare what you actually need against what any paid tool offers.

When CoreLock may be what you want

CoreLock is the right choice when your primary goal is security visibility.

If you want to know what is running on your Mac, CoreLock shows your busiest processes and flags known-bad tools. If you want to know which apps have access to your camera or microphone, CoreLock lists those permissions. If you want to check that your apps are signed, CoreLock checks the code signatures of apps in your Applications folders.

CoreLock is also a fit if you want a security tool whose core scanning runs on your Mac. AI explanations are off by default. When on, they send a summary to our servers, and your files are not uploaded; the privacy policy lists exactly what is sent.

Can you use both?

CoreLock is a separate Mac app. Cleanup and security are different jobs, so many people use a tool for each. Whether CoreLock runs well next to a particular optimizer depends on that optimizer, so check its documentation if you plan to run both.

Bottom line

If you want to clean your Mac, use a tool built for cleanup. If you want to see what is running on your Mac and what has access to it, CoreLock is built for that. If you want both, use both.

CoreLock gives you a working security tool at no cost: the full six-check scan, unlimited scans, and 3 AI scan reviews a day. No trial that expires.
