Installing Mac Cleaner Pro

Mac Cleaner Pro v1.0 ships without notarization while we bootstrap. macOS Gatekeeper will warn you on first launch. This is a one-time workaround — every subsequent launch opens normally.

Step 1 — Drag to Applications

Open the downloaded MacCleanerPro-1.0.7.dmg.
Drag Mac Cleaner Pro onto the Applications folder shortcut.
Eject the DMG.

Step 2 — Verify the download (optional, 5 seconds)

Every release publishes a SHA-256 hash. Because this build isn’t notarized, this is how you confirm the file you downloaded is the file we built:

shasum -a 256 ~/Downloads/MacCleanerPro-1.0.7.dmg

Compare the output with the hash on the release page. If they differ, don’t open it — tell us.

Step 3 — First launch (one-time approval)

On first launch, macOS shows a dialog saying it can’t verify the developer, and offers only Done or Cancel. That’s Gatekeeper reporting, accurately, that this build isn’t notarized — we haven’t paid Apple’s $99/yr developer fee yet. Approve it once:

Open the Applications folder in Finder.
Right-click (or Control-click) Mac Cleaner Pro.
Choose Open from the context menu.
Click Open in the confirmation dialog.

After this once, double-clicking will always work.

Why is this needed? Apple requires every distributed app to be signed by a paid Developer ID and notarized through their service. Until donations cover that fee, we ship ad-hoc signed builds that work identically — Gatekeeper just adds a one-time prompt. The source is public, and every release publishes a checksum, so you don’t have to take our word for what’s in the build.

Step 4 — Grant Full Disk Access

The first-run wizard will guide you through this. You'll need to:

Open System Settings → Privacy & Security → Full Disk Access.
Toggle Mac Cleaner Pro on.

Without Full Disk Access, scans will only find a fraction of what's reclaimable.

What's currently disabled

A few features require a privileged helper daemon, which itself requires the paid Developer ID:

System cache cleanup (/Library/Caches/*)
App leftovers in /Library/LaunchDaemons/, /Library/PrivilegedHelperTools/

These appear in the UI with a Requires helper badge so you know what's there. They'll light up automatically in a future release.

Uninstalling Mac Cleaner Pro

The cleanest way: open Mac Cleaner Pro, go to App Uninstaller, search for "Mac Cleaner Pro", and use it to uninstall itself. Otherwise, drag Applications/Mac Cleaner Pro.app to the Trash and (optionally) remove ~/Library/Application Support/MacCleanerPro/ for a complete cleanup.
