About CoreGuard
An honest, local-only Mac health monitor — it observes and explains, and it never cleans, optimizes, or deletes a single file.
Why CoreGuard exists
Most Mac “cleaners” and “optimizers” make money by inventing problems — scary scans, fake “junk found,” one-click fixes for things that were never wrong. CoreGuard does the opposite. It’s a passive diagnostic: it reads the numbers your Mac already knows — temperatures, fan RPM, battery health, SSD wear (real SMART data), and what’s using your CPU — and explains them in plain English. It never cleans, optimizes, speeds up, repairs, or deletes anything, and it isn’t an antivirus. When something is genuinely wrong, you see it; when nothing is, it stays quiet and out of your way.
Who builds it
CoreGuard is built and maintained by an independent developer, not a data company.
Every release is Developer-ID signed and notarized by Apple — the same security checks
Apple runs on software sold outside the App Store. The app makes zero network connections:
no account, no cloud, no sync, no telemetry, no analytics, no crash reporting. There is nowhere for your
data to go, and you don’t have to take our word for it — open Little Snitch, or run
lsof -i -nP | grep CoreGuard and you’ll see no connections. More ways to check every claim are
on the proof bay.
How it’s sold
CoreGuard is a one-time purchase, not a subscription — pay once, and every
1.x update is included. Every danger and health warning is free, forever;
Pro adds the power tools (fan control, SSD endurance, power analytics, process and disk tools) and a
portable Condition Report you can hand to a buyer or a repair shop. A 30-day money-back
guarantee backs Pro and Family. See the full breakdown on Pricing.
Honest about limits
CoreGuard shows real SMART data and wear trends, but no honest tool can predict an exact drive-failure date — and it won’t invent one. It’s a diagnostic, not a repair tool or a substitute for professional service. We’d rather be useful and truthful than loud. The same principle runs through our Insights — in-depth, no-hype guides to what your Mac is actually doing.
