Body
Disk Usage with swiftDialog is a self‑service macOS tool that scans your Mac for large folders, saves two reports on your Desktop, and links you to Apple’s storage help article “Free up storage space on Mac.”
Purpose of this tool
-
Help you see what is taking up space on your Mac so you can clean up before upgrades or when you are running low on storage.
-
Provide quick access to Apple’s official Apple Storage Information article for next steps.
What the tool does
When you launch the Disk Usage tool from Self Service:
How to run the Disk Usage tool
-
Open Mosyle Manager.app Self Service on your Lane‑managed Mac (Found in your Applications folder).
-
Go to the "My Scripts" section. Find and click the Disk Usage item.
-
In the window that appears, review the description and click Continue to start the scan.
-
Wait while the progress window shows the scan status and percentage. The scan can take several minutes, depending on how much data you have.
-
When complete, a final window appears confirming that analysis finished and that reports were saved to your Desktop.
Files created on your Desktop
After the scan finishes, you will see two new text files on your Desktop:
-
<ComputerName>-Volume-Usage-<timestamp>.txt
-
Shows the 50 largest directories on your main disk (excluding system files).
-
<username>-Home-Usage-<timestamp>.txt
-
Shows the 50 largest directories in your home folder.
Each file includes:
-
A header with your Mac’s name, volume name, and free space summary.
-
A list of entries with size in GB and the corresponding folder or file path (largest first).
Example of a generated report file
Using the “Apple Storage Information” button
In both the initial and completion windows, there is an Apple Storage Information info button:
-
Clicking this button opens Apple’s Free up storage space on Mac article (KB 102624).
-
The article explains:
-
How to open System Settings > General > Storage in macOS Ventura or later.
-
Ways to temporarily free up space, such as clearing caches in safe mode.
Use this resource together with your report files to decide what you can safely remove or move to external or cloud storage.
Time Machine snapshot notes in the home report
The home‑folder report includes a Time Machine Information section at the end:
-
If Time Machine is not configured, it notes that no destination is set.
-
If Time Machine is configured, it lists local Time Machine snapshots on your Mac and includes advanced, unsupported command‑line examples ( tmutil thinlocalsnapshots ) that can permanently delete local snapshots to reclaim space.
These commands are intended for advanced use only; do not run them unless instructed by IT, as they permanently remove local backup data.
What to do after reviewing your reports
After you open the reports and Apple’s storage article:
-
Identify large folders you no longer need and delete or archive them (for example, old downloads, large media folders, or outdated project folders).
-
Consider moving large but important items to:
-
External drives.
-
Approved network/cloud storage options (such as LCC Union network storage, Google Drive, or other institution‑approved services).
-
Use System Settings > General > Storage to follow macOS recommendations like Store in iCloud, Optimize Storage, or Empty Trash Automatically when appropriate.
If you are unsure whether it is safe to delete something, or if you still cannot free enough space, contact the IT Help Desk with your two report files attached so staff can assist.
