4.1 System Requirements and Preparation

Before installation, please ensure your Mac is running macOS 10.13 High Sierra or later. Support for the latest macOS 15 Sequoia has also passed internal testing. We recommend backing up important data before operation to avoid accidental file deletion.

Make sure SIP is disabled. How to disable: Restart your Mac, hold Command+R to enter Recovery Mode, type “csrutil disable” in Terminal and press Enter. After installation, you can re-enable SIP to enhance system security.

4.2 Download and Installation Steps

Download the Disk Diet v5.6.0 activated version from the link provided on this page. The file is in DMG format, approximately 15MB. Double-click the DMG file to mount the disk image, then drag the Disk Diet icon to the “Applications” folder.

On first launch, the system may prompt “Cannot verify developer.” In this case, go to “System Preferences – Security & Privacy – General” and click “Open Anyway.” Then enter the administrator password to authorize running.

4.3 Activation and Initial Configuration

After the software starts, click “Disk Diet – Enter License” in the menu bar. Paste the activation code in the pop-up window and click “Activate.” After successful activation, it is recommended to go to “Preferences – General” and check “Launch at login.”

For the first scan, we recommend selecting “Quick Scan.” After scanning, the software will list cleanable files. Check all options and click “Clean.” The entire process takes about 2-5 minutes.

5. FAQ

5.1 Why is there no significant change in disk space after cleaning?

This is usually because the system generates new cache files in the background. We recommend restarting your Mac before checking disk space again. Additionally, some files such as the “Other” category cannot be fully identified by Disk Diet, so you can use it in conjunction with the system’s built-in “Storage Management” tool.

5.2 Will Disk Diet accidentally delete my important files?

The software has built-in safety mechanisms. By default, it cleans non-critical data such as caches, logs, and temporary files. For mail attachments and download folders, we recommend previewing the contents before deletion. We have tested dozens of scenarios and have not found any cases of accidental deletion of system files.

5.3 How to recover accidentally deleted files?

Disk Diet does not have a built-in recycle bin. After accidental deletion, you should immediately stop using your Mac and use data recovery software such as Disk Drill to attempt recovery. Regular Time Machine backups are the best practice to avoid data loss.

5.4 Does the software support Apple Silicon chips?

Fully supported. Disk Diet v5.6.0 has been natively optimized for M1, M2, and M3 series chips. It can also run in Rosetta 2 mode, but using the native version is recommended for better performance.

5.5 Why is it necessary to disable SIP?

Some system logs and cache files are located in protected system volumes. Only after disabling SIP can Disk Diet gain full access. If not disabled, some features of the software will be limited, and cleanup effectiveness will be reduced.

5.6 What if the activation code is invalid?

The activation codes provided on this page have been strictly tested. If you encounter an invalid code, please check whether you have entered extra spaces. If the problem persists, please leave a comment to contact us, and we will update the available activation codes promptly.

5.7 Do I need to reactivate after a software update?

Usually, minor version updates do not require reactivation. If it is a major version update (e.g., from v5.5 to v6.0), you may need to re-enter the activation code. We recommend following the official update log.

7. Usage Tips and Real-World Cases

7.1 Deep Cleaning Tips

Regular scans can only clean surface-level junk. To free up more space, we recommend using “Deep Scan” mode. This mode analyzes temporary files in all user directories on the system. Our tests found that deep scan identifies an average of 2-3GB more redundant data than quick scan.

For developer users, we recommend regularly cleaning Xcode Derived Data. This folder typically occupies 5-10GB. In Disk Diet, simply check the “Developer Tools” option to clean it automatically. Back up your current projects before operation to avoid losing build configurations.

7.2 Real-World Case: Rescuing a 128GB Hard Drive

A designer using a 128GB MacBook Air had their hard drive in a “full” state for a long time. After deep cleaning with Disk Diet, 18.7GB of space was freed. Among this, mail attachments accounted for 6.2GB, iOS update packages for 4.5GB, and system logs for 3.8GB.

After cleaning, system startup speed improved by about 30%, and Adobe software launch time was reduced from 45 seconds to 28 seconds. The user reported that running a quick scan once a month is sufficient to maintain hard drive health.

7.3 Setting Up Scheduled Cleaning Plans

In “Preferences – Schedule,” you can set up automatic weekly cleaning. We recommend setting it for Monday at 10 AM, when system load is lower. Check “Notify before cleaning” to view the list of files to be deleted, avoiding accidental operations.

For team users, Disk Diet can be installed on multiple Macs and configured uniformly through MDM policies. This ensures all devices maintain optimal storage status and reduces IT maintenance workload.

8. Summary

Disk Diet v5.6.0 is a time-tested disk cleanup tool. Through its simple interface and powerful scanning engine, it helps users safely free up disk space. Both regular users and developers can benefit from it.
