Cleanup My System is a system optimization and cleanup tool designed specifically for macOS. Its core goal is to help users quickly identify and remove junk files, manage applications, optimize startup items, protect privacy, and free up disk space, thereby effectively improving the overall speed and performance of the Mac. This guide will detail its core interface, complete operation process, and practical tips. Whether you are a new Mac user or a veteran seeking deep optimization, you will find methods to improve efficiency.
After launching Cleanup My System, you will see a clear and intuitive main interface, mainly divided into the following areas:
Double-click to launch Cleanup My System. By default, it enters the “System Overview” interface. The software usually prompts or automatically starts a quick system scan to assess storage space and performance status.
Command + R).

Simply click the red close button in the upper left corner of the screen to exit the software. All cleanup operations are completed in real-time when you click “Clean” or “Uninstall”; there is no need to separately “Export” or “Save Project”.
Spacebar to use macOS Quick Look to preview the content, ensuring you do not accidentally delete important documents.To help you use Cleanup My System more smoothly, we have compiled some frequently encountered problems and solutions from users.
| Problem | Possible Cause | Solution |
|---|---|---|
| After scanning, “Cleanable” files show 0 bytes | 1. A thorough cleanup was recently performed. 2. The scan module did not fully load or an error occurred. |
1. Wait a while (a few days) before scanning again. 2. Try exiting and restarting Cleanup My System, then scan again. |
| After cleaning browser data, website login status is lost | The cleanup options included “Cookies”, and cookies store website login session information. | Next time you clean, expand the browser options in “Privacy Protector” and uncheck “Cookies”, cleaning only cache and history. |
| Prompt “Cannot delete” when uninstalling an application | The application is running, or related processes are active in the background. | Ensure the target application is completely exited (including right-clicking to quit on the Dock), then retry the uninstall operation. |
| Software runs slowly or scan gets stuck | 1. The disk being scanned has an extremely large number of files. 2. Temporary conflict with macOS system or other security software. |
1. Be patient; the first full disk scan may take a long time. 2. Try temporarily disabling other security or disk tools, then restart this software. |
| Important files accidentally deleted | The checked file list was not carefully reviewed before cleaning. | Immediately check the macOS “Trash”. If the files were moved to the Trash, you can restore them from there. If “Secure Delete” was used, they usually cannot be recovered. Always develop the habit of previewing and confirming before final cleanup. |
| Software cannot start normally | System version incompatibility or permission setting issues. | Check whether the macOS version meets the software requirements, and try allowing the software to run in “System Preferences” > “Security & Privacy”. |
Important Reminder: Any system cleanup tool has potential risks. Before performing cleanup (especially deleting large files, old files, or uninstalling applications), be sure to use the preview function to confirm file contents and ensure you have backups of important data.
Mastering some advanced tips can help you get twice the result with half the effort when using Cleanup My System. Here are some practical experiences shared by veteran users.
A designer user reported that her Mac storage space was chronically low. We suggested she follow this order: First, use “Large & Old File Finder” to filter files over 500MB, finding several old design software installers and uncleaned virtual machine snapshots, directly freeing 8GB. Next, use “Smart Cleanup” to clean system caches and logs, freeing another 5GB. Finally, through “Application Manager”, completely uninstall 3 old software programs no longer used and clean their residual files, ultimately freeing over 20GB of space in total.
Many users worry that cleaning cookies will cause website login information to be lost. A compromise solution
