DiskWatch — see where your disk space went.
A small menu bar app for Mac. Live free space, a desktop widget, a full report of what is taking room, and a safe way to clear it.
Live reading
🟢 142 GB in the menu bar, refreshed every minute. Yellow under 15%, red under 5%.
Full report
Biggest folders and files, what kind of thing each is, and how long since it was touched.
Safe clean-up
Caches pre-ticked, everything goes to the Trash — never deleted outright.
Private
Your files never leave the Mac. Only your licence is checked online.
Help
Installing
Sign in → Download → open DiskWatch-…pkg. The first time macOS refuses it (no Apple signature yet): System Settings → Privacy & Security → Open Anyway, or right-click the .pkg → Open → Open.
Activating
After installing, DiskWatch asks you to Activate: sign in with the same account. If you were given a DW1-… key, enter it on Create account or in Account → Licence.
Using it on another Mac
Your licence allows a number of Macs. Account → Macs lists them; remove one to free its place.
“DiskWatch is not activated”
The licence is re-checked every 15 minutes. Offline it keeps working for a day. If the licence was revoked or ran out, enter a new key in Account.
Permissions
For a complete scan add DiskWatch under System Settings → Privacy & Security → Full Disk Access. DiskWatch's Settings → Permissions has a button for it.
Uninstalling
Quit DiskWatch, drag /Applications/DiskWatch.app to the Trash, and remove the two com.niyanta.diskwatch files in ~/Library/LaunchAgents.
