Disk Tracker v0.1.2 — Find the 40 GB you forgot about
What's new in v0.1.2
Developer Caches. A new sidebar entry that measures the caches your dev tools leave behind — Xcode (DerivedData, device support, archives), the Simulator, Homebrew, npm/Yarn/pnpm, pip, Cargo, Gradle and Android — with one bar showing which tool takes the most. The caches in your home folder's hidden folders (npm, Cargo, Gradle, Android) can go straight to the Trash; for the rest, each row shows the tool's own cleanup command, ready to copy. It asks once for access to your home folder.
A new icon for macOS 26. The icon is now a Liquid Glass icon that follows macOS 26's light, dark, clear and tinted styles. macOS 15 gets the same design, flattened.
Fixes.
- Home now scans your home folder. It used to scan the app's own sandbox folder instead.
- Move to Trash works on scans reopened from History after a restart.
- Nothing inside a Library folder can be moved to the Trash any more — apps keep live data there. Those items point you to Show in Finder instead.
- When macOS won't let the app delete from a folder you didn't choose, the message now says how to fix it: open the folder with Choose Folder….
- In full screen, the sidebar stays at the left edge instead of drifting toward the middle.
- The welcome screen no longer draws a second, fake window inside the real one.
- Scans no longer wait behind low-priority background work.
Privacy and security.
- Release builds no longer allow a debugger to attach to the app. Earlier builds did.
- The scan engine is now sandboxed in its own right and runs inside the app's sandbox.
- A privacy manifest and a privacy policy: nothing leaves your Mac.
Installing
- Open
DiskTracker-v0.1.2.dmgand drag Disk Tracker to Applications. - Run this once in Terminal:
xattr -dr com.apple.quarantine /Applications/DiskTracker.app - Open it normally.
Step 2 is required because this build is ad-hoc signed rather than
notarized — Apple notarization needs a paid Developer Program membership.
The command clears the "downloaded from the internet" flag on this app only;
it does not disable Gatekeeper system-wide, and the signature stays valid.
Right-click → Open does not work for ad-hoc signed apps on Apple
Silicon. Thexattrcommand is required.
Requires macOS 15.0 or later.
