Mop Up for Mac
Clear out the junk your Mac collects, uninstall apps along with the files they leave behind, and see where your disk space has gone. Nothing is removed until you say so.
$ brew tap RossNicholson/tap $ brew trust --cask rossnicholson/tap/mopup $ brew install --cask mopup
Homebrew 7 asks you to trust casks from other taps. On older versions, skip the brew trust line.

What it does
No Terminal, no jargon. Every job shows you what it found first, and you decide.
01
Mop Up looks through app caches, logs, browser leftovers, developer files and bits left behind by apps you've deleted. You see how much it found and where, file by file if you like, before anything is cleaned. Big things it won't touch on its own, like old iPhone backups, are listed separately so you can decide.
02
Dragging an app to the Trash leaves its settings, caches and support files behind. Mop Up finds them too. Pick the apps, check the list of files, then move everything to the Trash, where you can still get it back. Apps that are open have to be quit first, so nothing unsaved is lost.
03
The routine maintenance macOS doesn't do on its own. Mop Up refreshes Finder, Spotlight and network caches, checks preferences, login items and launch agents, and fixes what it safely can. You can check first without changing anything.
04
See the biggest places on your Mac, then open folders to look inside. Things that are safe to clean are labelled. Show anything in Finder, or move it to the Trash from right there.
05
A health score, free disk space, memory, processor and battery, updated live. Mop Up also sits in the menu bar with your free space, so you know when it's time for a clean. Drag the corner of its panel to make it bigger.
Careful by default
A cleaner should never surprise you. These are the rules Mop Up works by.
Every clean-up and uninstall shows you what it found first. Nothing happens until you press the button.
Uninstalled apps and anything you remove in Disk Space go to the Trash, so you can change your mind.
Clean Up only clears things apps rebuild on their own, like caches and logs. Your documents, photos and music are never part of it.
Caches of running apps are left alone, and an app has to be quit before it can be uninstalled.
Every clean-up, uninstall and tune-up is listed, with how much space it freed.
When a step needs admin rights, a password dialog asks first. Your password goes straight to macOS and is never saved or sent anywhere.
Take a look
Built in SwiftUI, with no Electron. It follows your Mac's light or dark mode, and has a soapy bucket who's always happy to help.
Private by design
Every scan and clean happens on your Mac. Mop Up doesn't upload anything, anywhere.
No sign-up, no email address, no subscription. Install it and press Scan.
No analytics, no adverts and nothing collected. Ever.
Install Mop Up with the three commands above, or download it from GitHub. It's free, open source, and signed and notarized by Apple.
