DiskSlim Mac Cleaner for Mac v12.1.6 Chinese Activated Version Download

Regularly performing systematic cleaning on your Mac and removing unnecessary files is an effective way to free up storage space and improve system efficiency and responsiveness. Among these, cleaning specific directories such as the “Downloads” folder often quickly recovers a large amount of disk space and is an important daily maintenance practice. Many users find that after long-term use, Mac storage space is quietly occupied by various caches, logs, and duplicate files. If not handled in time, it not only affects boot speed but may also cause professional software to lag. Mastering the correct cleaning strategy can keep your Mac at peak performance.

1. Recommended File Types to Clean

To achieve the best cleaning results, we recommend focusing on the following file types:

• Old files: Documents that have not been accessed for a long time or are outdated. These files often hide in corners of “Documents” or “Desktop,” such as project backups from years ago, occupying space without providing value.
• Large files: Single files that take up huge storage space. For example, project files left over from video editing or high-definition movie images, often several GB in size, are primary targets for cleaning.
• Zero-byte files: Invalid files with no actual content. These files are usually remnants produced by software crashes or abnormal interruptions. Although small in size, they can slow down file indexing when accumulated.
• Empty folders: Directories containing no files. Many improperly uninstalled apps leave behind empty shell folders, which are time-consuming and laborious to delete manually.
• Duplicate folders: Redundant folders with identical content. For example, folders with the same name created by accidental copying, or copies generated during iCloud syncing.
• Similar photos: Multiple images with highly repetitive or similar content. Photos taken in burst mode and repeated screenshots are key cleaning targets.

2. Scannable File Categories

With professional cleaning tools (such as DiskSlim), you can deeply scan and categorize the following common file types:

• Images
• Videos
• Audio files
• Archives
• Folders
• PDF documents
• Other files
• Recently used files

DiskSlim’s scanning engine is specially optimized to quickly traverse the entire disk. It leaves no corner unchecked, including system cache directories, user libraries, and Time Machine local snapshots. After running a full scan, the software sorts files by category, size, and last access time, giving you a clear view of which files should be cleaned first.

5. Detailed Installation Tutorial

Many beginners do not know how to proceed after downloading a DMG file. Here is a step-by-step installation guide.

Step 1: Download and Extract

Click the download link above to obtain the DMG installer for DiskSlim v12.1.6. After downloading, double-click the DMG file to mount it on the desktop.

Step 2: Drag and Drop Installation

In the pop-up window, you will see the DiskSlim icon on the left and the “Applications” folder icon on the right. Use your mouse to drag the left icon into the right folder. This is the most standard installation method for Mac software.

Step 3: First Launch Settings

Go to the “Applications” folder, find the DiskSlim icon, and double-click it. Because this is software downloaded from the internet, macOS may display a security prompt. Please go to “System Preferences” -> “Security & Privacy” -> “General” and click the “Open Anyway” button.

Step 4: Grant Permissions

On first run, DiskSlim will request “Full Disk Access” permission. This is to allow it to scan system files, caches, and logs. Please be sure to check DiskSlim in “System Preferences” -> “Security & Privacy” -> “Privacy” -> “Full Disk Access.”

Step 5: Start Cleaning

After authorization is complete, the main interface will display current disk usage. Click the “Start Scan” button, wait a few minutes, and then you can view the scan results and choose what to clean.

6. FAQ

We have compiled the following answers to frequently asked questions:

Q1: Will DiskSlim accidentally delete my important files?

No. DiskSlim has a built-in intelligent recognition mechanism. For system files and commonly used software dependency libraries, the software marks them as “Recommended to Keep.” Before cleaning, all files to be deleted are listed, and you can check and confirm each item.

Q2: Why does the scanned space appear larger than the actual disk space?

This is because DiskSlim includes system caches, temporary files, and Time Machine local snapshots in its calculation. Although these files occupy space, they are usually hidden by the system. The software scans for “cleanable” potential space.

Q3: What should I do if the system becomes laggy after cleaning?

Please check whether system cache files were accidentally deleted. We recommend using DiskSlim’s built-in “Restore” function. This function is in “Cleaning History” and can restore the most recent cleaning operation with one click.

Q4: Can DiskSlim clean WeChat and QQ caches?

Yes. Under the “Application Caches” category, DiskSlim can accurately locate chat history caches and image caches of social software such as WeChat, QQ, and DingTalk. You can choose to clean only expired files and keep recent chat history.

Q5: What is the difference between the activated version and the free version?

The v12.1.6 Chinese activated version provided on this page unlocks all advanced features, including “Similar Image Finder,” “One-Click Duplicate File Cleaner,” and “Large File Visual Map.” The free version can only scan and cannot perform one-click batch cleaning.

Q6: Does the software support macOS Ventura and Sonoma?

Fully supported. DiskSlim v12.1.6 has been compatibility-tested for macOS 13 (Ventura) and 14 (Sonoma). It also runs stably on the latest macOS 15 Sequoia.

Q7: Why does it prompt “Resource Busy” when I drag to install?

This is usually because you have already opened DiskSlim before. Please right-click the DiskSlim icon in the Dock, select “Quit,” and then drag to install again.

Q8: Can I set an exclusion list when cleaning the “Downloads” folder?

Yes. In the software’s “Preferences” -> “Exclusion List,” you can add folders or file extensions that you do not want to be scanned. For example, if you want to keep all .dmg installers, you can add “.dmg” to the exclusion list.
