DadWare

Scans your Mac. Grades your storage. Tells you what to clean up.

Download for Mac

macOS only. No install needed. ~8.5 MB.

I built this to help my daughter understand what's taking up space on her Mac. I thought it could also teach her about how to use the terminal which is becoming cool again.

What it does

Grades your storage from A to F. Free space, Downloads clutter, Photos library, the works.
Finds the big stuff. Your largest files and folders, ranked by size.
Checks your memory. Shows what apps are hogging RAM and whether you should worry.
Opens a report in your browser with charts, grades, and advice.
Never deletes anything. Read-only. You figure out what you want to delete.

How to run it

Download the file and move it somewhere (Desktop, Downloads, wherever)
Select the file and press Cmd-I (Get Info)
Under Sharing & Permissions, make sure your user has Read & Write
Double-click the file. Terminal opens and the scan starts.

Replace this with an actual screenshot (680px wide works well)

macOS may show a security warning the first time. Right-click the file, choose Open, and click Open again. You only have to do this once.

Want to scan Photos, Messages, and Mail?

The scan works without any setup, but to see your Photos, Messages, and Mail library sizes, you need to grant Full Disk Access:

Open System Settings
Go to Privacy & Security
Scroll to Full Disk Access
Add Terminal.app and make sure it's checked
Restart Terminal and run the scan again

Nerdy version (Terminal)


                # Make it executable and run the storage scan

                chmod +x ~/Downloads/yourdad

                ~/Downloads/yourdad

                

                # Scan CPU and memory

                ~/Downloads/yourdad cpu

                

                # Scan everything

                ~/Downloads/yourdad all

                

                # Or copy it to your PATH and use it from anywhere

                cp ~/Downloads/yourdad /usr/local/bin/

                yourdad

Safe by design. This tool only reads your files. It never deletes, modifies, or uploads anything. No account, no tracking, no data leaves your Mac. The source code is public if you want to check.
