Clean up your Mac, honestly.
MacVac finds the clutter that builds up on every Mac and shows you exactly what it has found before anything is removed. No subscription, no upsell, ever.
One click. Every module. No guesswork.
Smart Scan checks system junk, game leftovers, browser caches, large files and duplicates in a single pass, with a live running total of the space it can reclaim. Nothing is removed until you decide.
Safe Clean takes care of the low-risk categories automatically. The Uninstaller, Login Items and Memory Optimiser always remain separate, deliberate steps, because quitting an app or disabling a background process is not the same as clearing a cache.
Built to be checked, not just believed.
Removals go to the Trash by default, so a mistake is only ever one click from undone; permanent deletion is a separate opt-in setting that stays off unless you enable it. The Activity Log records every folder MacVac inspects and every file it touches, written to a plain-text file on disk that you can open and read for yourself.
There is 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.
macOS offers no supported way for a regular app to force the system to free memory, and tools that claim otherwise rarely deliver. What genuinely works is quitting the apps that are holding on to memory, so that is exactly what MacVac does.
It shows live memory usage for every running app, drawn from the same data Activity Monitor uses: measured, not estimated.
Speaks your language
Everything else in the box
The rest of the toolbox, from caches to battery health.
System Junk
Caches, logs, saved app states and temp files.
Game Leftovers
Shader caches from Steam, Epic, GOG and more. Save files are never touched.
Browser Cache
Chrome, Edge, Brave and Firefox. Never history or passwords.
Mail Attachments
Apple Mail's local attachment cache, re-downloadable on demand.
Large & Old Files
Any folder, your size threshold, one-click shortcuts.
Duplicate Finder
Matches verified with SHA-256 hashes, never a guess.
Uninstaller
Removes an app and everything it left behind, together.
Login Items
See what launches at login, with live memory usage shown.
Battery Health
Cycle count and condition, detail most cleaners skip.
Activity Log
Every scan, every file moved, recorded independently.
Protection Status
Gatekeeper and XProtect status, at a glance.
Download and install
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 notarised yet
MacVac is not yet signed with an Apple Developer ID or notarised, so macOS will block a normal double-click on first launch. This is expected behaviour and nothing is 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 annual subscription for things your Mac ought to be able to do on its own.
So this one is free. There is no locked tier, no trial and nothing to upgrade to, and it will stay that way.
Entirely optional. A coffee changes nothing about the app either way.
