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.
For Mac · macOS 14 or later · Free · Installs with Homebrew · Open source
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. It also empties your Trash, so check there for anything you still want first.
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 until the Trash is emptied. 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 until it's emptied.
Apart from emptying the Trash, Clean Up only clears things apps rebuild on their own, like caches and logs. It never goes through your documents, photos or music.
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, open Clean Up and press Scan my Mac.
No analytics, no adverts and nothing collected. Ever.
Mop Up is free. It installs with Homebrew, a free and widely used tool for installing Mac apps and keeping them up to date. You only need to set it up once.
Get Homebrew. Download the installer, open it and click through, like any Mac installer. It asks for your Mac password. Already have Homebrew? Skip to step 2.
Download HomebrewOpen Terminal, an app that comes with every Mac. Press ⌘ Space, type Terminal and press Return. A window with a blinking cursor opens.
Click Copy, paste into Terminal with ⌘ V and press Return. Text scrolls past while Homebrew installs Mop Up. It's done when it stops.
$ brew tap RossNicholson/tap$ brew trust --cask rossnicholson/tap/mopup$ brew install --cask mopup
See command not found: brew? Quit Terminal with ⌘ Q, open it again and paste once more.
Open Mop Up from your Applications folder. If your Mac asks whether you're sure you want to open it, click Open. Then open Clean Up and press Scan my Mac.
Your Mac checks with you before an app can do certain things. Here's what Mop Up asks for, and what to click.
On an older Homebrew, an error about brew trust is safe to ignore.
Mop Up is free, open source, and signed and notarized by Apple.
