Install DiskTidy
Download the disk image, open DiskTidy.dmg, and move DiskTidy to your Applications folder. Launch it from Applications so macOS can verify the notarized build.
Your first scan is free. DiskTidy shows disk, AI tool, duplicate, project, and system-health findings before you decide whether Personal Pro cleanup is useful for you.
Verify the download
Advanced users can compare the SHA-256 file published alongside the installer. The checksum lets you confirm that the downloaded disk image matches the public build on this website.
Free and Personal Pro
Free includes unlimited disk and AI-tool scans, vibe-project discovery, health signals, visible cleanup candidates, and limited manual deletion. Personal Pro is a $39 one-time purchase that unlocks Safe Clean, Full Clean, duplicate deletion, and unlimited manual deletion on up to three personal Macs.
