CLMM stands for Clean My Mac CLI. It is a command-line tool for macOS that helps you check system health, find large files, review space use, and clear common junk that builds up over time.
It gives you a simple way to inspect your Mac without opening a full desktop app. You run a command, read the results, and decide what to clean.
Visit the GitHub Releases page to download and run this file.
On that page, look for the latest release. In most cases, you will see files that you can open or run after they finish downloading.
- Open the Releases page.
- Find the latest version at the top.
- Download the file for your Mac.
- Open Terminal.
- Run the app from the folder where you saved it.
- Follow the on-screen prompts.
If you are not sure which file to use, pick the one that matches your Mac and the download notes on the release page.
This tool is made for macOS.
You will need:
- A Mac with macOS installed
- Permission to run command-line tools
- Terminal access
- Enough free disk space to extract the download
- A recent version of Node.js if you run the source version
For most people, the release download is the easiest way to start.
After you download the release, follow these steps.
Press Command + Space, type Terminal, then press Return.
If you saved the file in Downloads, use:
cd ~/Downloads
Use the file name from the release you downloaded. If the file is marked as executable, run it from Terminal.
Example:
./clmm
If the release package includes a named command, use that name instead.
If you want to check the available commands, run:
clmm --help
Use the health check command to look over the main parts of your Mac.
This command can show:
- Free disk space
- Memory use
- Swap use
- SMART drive status
- Login items
- Cache size
It helps you spot common issues before they slow your Mac down.
CLMM includes cleanup commands for common space hogs.
Use this to remove safe-to-clear junk files, such as:
- App cache files
- System cache files
- Temporary files
- Old logs
- Download leftovers
The tool keeps the process simple and shows what it plans to clear before it acts.
Use this when you want to see what would be removed without deleting anything.
If your Mac is filling up, CLMM can help you find where space is going.
This command can list:
- Large folders
- Big files
- Common storage hotspots
- Space use by category
It is useful when you know your drive is full but do not know why.
Some slowdown comes from too many background items.
This command can show login items and background apps that start with macOS.
You can use it to spot apps that launch without your help.
Cache files can help apps load faster, but too much cache can waste space.
This command helps you inspect cache use by app and folder.
It gives you a clear view before you decide to remove anything.
Here are a few simple ways to use CLMM.
clmm check
clmm disk
clmm startup
clmm clean
clmm clean --dry-run
CLMM is built to give you control.
It does not try to hide what it is doing. It shows you the result of each command and lets you decide what to do next.
Helpful habits:
- Start with
clmm check - Use
clmm clean --dry-runfirst - Review large files before removing them
- Keep copies of files you may need later
The release page may include one or more of these:
- A ready-to-run macOS file
- A ZIP file with the app inside
- A command-line package
- Build notes for advanced use
If you only want the easiest path, use the latest release and follow the download notes on the page.
If macOS blocks the file, check these items:
- Make sure the download finished
- Make sure you are in the right folder
- Make sure the file has execute permission
- Make sure you typed the file name correctly
- Make sure you downloaded the macOS release
If the file name has spaces, wrap it in quotes.

./"clmm clean"
