Clean up your Mac, honestly.
MacVac finds the clutter every Mac collects and shows you exactly what it found before touching anything. No subscription, no upsell — ever.
One click. Every module. No guesswork.
Smart Scan checks system junk, game leftovers, browser cache, large files and duplicates in a single pass, then shows you a live running total of everything it can reclaim before you commit to anything.
Safe Clean handles the curated, low-risk categories automatically — Uninstaller, Login Items and Memory Optimiser always stay separate, deliberate decisions, because quitting an app or disabling a background process isn't the same thing as clearing a cache file.
Built to be checked, not just believed.
Every removal goes to the Trash by default, so a mistake is always one click from undone — permanent deletion exists only as a separate opt-in setting, switched off unless you turn it on. The Activity Log records every folder MacVac has looked at and every file it's touched, written to disk independently of the app, in a plain-text file you can open yourself.
There's no analytics SDK, no crash reporter, and no
URLSession call anywhere in the codebase. MacVac has no
way to phone home, because it was never built with one.
No placebo "Boost" button.
There's no legitimate API for a regular app to force macOS to free RAM — that's root-only, and most "memory cleaner" tools that claim to do it are placebo. What actually works is quitting apps that are genuinely holding onto memory, so that's the only thing this does.
Live, real memory usage per running app, pulled from the same data Activity Monitor uses — not an estimate, not a guess.

Removes an app and everything it left behind, together.

Activity Log
Every scan, every file moved, recorded independently.
Protection Status

Getting the app
Download the DMG, open it, and drag MacVac into Applications.
SHA-256:
Verify after downloading:
shasum -a 256 ~/Downloads/MacVac-.dmg
in Terminal, and check it matches.
Not notarized yet
MacVac isn't signed with an Apple Developer ID or notarized yet, so macOS will refuse to open it with a normal double-click on first launch. This is expected, not a sign anything's wrong:
- Right-click (Control-click) MacVac.app and choose Open.
- Click Open again on the confirmation dialog.
If you already double-clicked and got a blocking "cannot be opened" message, go to System Settings → Privacy & Security and click Open Anyway next to the message about MacVac instead.
Hello, I'm Keith
I built MacVac in my spare time, mostly out of frustration. The big-name Mac cleaners charge a hefty yearly subscription for things your Mac ought to be able to sort out on its own, and I didn't fancy paying it.
So this one is free. Not free-with-an-asterisk — there's no locked tier, no trial and nothing to upgrade to. It will stay that way.
Buy Me a CoffeeOnly if you fancy it — a coffee changes nothing about the app either way.
