DaisyDisk is a visual disk space analyzer designed specifically for macOS. Through an exquisite interactive sunburst chart, it transforms complex disk usage into an intuitive and easy-to-understand visual presentation, helping users quickly locate and clean up the “culprits” occupying large amounts of space, thereby efficiently managing Mac storage space.
After launching DaisyDisk, its interface is mainly divided into the following core areas, each undertaking specific analysis tasks. Familiarity with these areas is the first step to efficient use of the software.
Operation: After launching DaisyDisk, select the disk to analyze (such as “Macintosh HD”) in the main interface or click “Scan Folder…” to select a specific directory. If you only want to check a certain project folder, this feature can save a lot of time.
Shortcut: Press Command + O to directly open the folder selection dialog. This shortcut is consistent with many native Mac applications, with extremely low learning cost.
Operation: After clicking the target disk, DaisyDisk starts scanning. The scanning progress will be displayed in animation form in the sunburst chart area. This process is automatic, and you only need to wait a moment.
Tip: The first scan of the entire disk may take several minutes, depending on disk size and file count. According to Apple developer documentation recommendations, it is advisable to perform the first full disk scan when the system is idle for optimal performance.
After scanning is complete, the complete sunburst chart will be presented. This is the moment for you to “dialogue” with data.
Operation Methods:
Command + [. This operation allows you to freely shuttle between different levels.Spacebar to use Quick Look to quickly preview file contents (applicable to supported file types). This can help you confirm whether the file is truly useless.Command + R. This is very convenient when you need to manually process files.This is the core step of cleaning up space. Please operate with caution to avoid accidentally deleting important data.
Operation Steps:
Shortcut: After selecting an item in the sunburst chart, press the Delete key to directly add it to the Collector. This is a key operation for improving efficiency.
After the deletion operation is complete, click the “Rescan” button on the toolbar (or press Command + R) to refresh the view and see the disk space freed after cleanup. This step allows you to intuitively see the cleanup results.
In addition to basic operations, DaisyDisk also hides some practical tips that can greatly improve efficiency. Master these, and you can advance from novice to expert.
In actual use, you may encounter some minor problems. Here is a detailed FAQ to help you quickly troubleshoot.
| Problem | Possible Cause | Solution |
|---|---|---|
| Scanning speed is very slow | First full disk scan, extremely many disk files, or other high-load applications running. | Wait patiently for the first scan to complete. Subsequent scans will use cache and be faster. Try closing unnecessary applications. According to Apple official support documentation, background processes can significantly affect disk read/write speed. |
| Unable to delete some files (delete button grayed out) | File is being used by another program, or user does not have corresponding permissions (such as system core files). | Close programs that may be using the file. For system files, DaisyDisk usually does not allow you to delete critical items to ensure system safety. Please focus on user directories (such as “Movies”, “Music”, “Downloads”). This is macOS’s sandbox mechanism protecting you. |
| Sunburst chart looks cluttered and difficult to distinguish | There are many tiny files in the current directory. | Use “File List” view for a clearer text list. Or zoom in on a specific area of the sunburst chart by dragging. You can also adjust “Minimum Sector Size” in the “View” menu to merge overly small files. |
| Want to know if a certain cache or log folder can be deleted | Unsure of the folder’s purpose. | Use “Show in Finder” to locate, then use “Spacebar” to quickly preview internal file contents for judgment. For folders named “.cache”, “.log”, “temp”, they can usually be safely cleaned, but it is recommended to move them to Trash first and observe whether the system runs normally. According to developer discussions on Stack Overflow, most third-party application caches can be safely deleted. |
| DaisyDisk prompts “Insufficient Permissions” | macOS privacy protection mechanism restricts software access to certain folders. | Go to “System Preferences” > “Security & Privacy” > “Privacy” > “Full Disk Access” and check DaisyDisk. This is a common setting in macOS 10.14 and later, not a software failure. |
| Disk space does not increase significantly after cleanup | Trash may not be emptied, or system snapshots are occupying space. | First empty the Trash. If using an APFS-formatted disk, the system may create local snapshots for Time Machine. Run the tmutil listlocalsnapshots / command to view, and use tmutil deletelocalsnapshots / to delete old snapshots (use with caution). |
| Software interface displays abnormally or lags | May be graphics driver issues or insufficient system resources. | Try restarting DaisyDisk or restarting Mac. Check if macOS is the latest version. Turning off “Animation Effects” in the “Display” menu can reduce graphics card load. |
| How to recover accidentally deleted files? | Selected “Delete Immediately” mode. | Immediately stop using the disk and use data recovery software (such as Disk Drill) to attempt recovery. However, success rate cannot be guaranteed. It is recommended to always prioritize “Move to Trash” mode. |
Mastering shortcuts is the best way to improve operational efficiency. The following table summarizes the most commonly used shortcuts in DaisyDisk. It is recommended to save for future reference.
| Function | Shortcut (Mac) | Description |
|---|---|---|
| Open/Scan Folder | Command + O |
Open dialog to select a specific folder for scanning |
| Rescan | Command +
