Try the beta.

Download for Mac

macOS 15 or later · Apple silicon and Intel · .dmg · 7.2 MB

Signed and notarized by Apple · Scanned on VirusTotal

Install it

  1. Download and open the .dmg. Drag DiskSpace AI to your Applications folder (if you had an earlier version, replace it).
  2. Open it. macOS reminds you it was downloaded from the Internet and that Apple checked it. Click Open.
  3. Give it access. The first time, it asks for access to some folders (and to Photos, if you use that part). If you had an earlier version, it asks one last time: from this version on, permissions stay across updates.

What’s new in 1.0.18

  • New help: one search box that filters the questions as you type (press Return to ask Apple's AI), “how it works” in three steps and the questions grouped by topic.
  • Every answer has a button to do it: show Recently Cleaned, open Photos or the Explorer, connect your AI agent… Plus related questions to keep reading.
  • New questions: whether the app is safe and signed by Apple, and how to share what you cleaned. Keyboard shortcuts, in a table.

What to try

  • Analyze your Mac and look at the map: does what it says about each folder make sense?
  • Clean the safe items and try Undo with one of your files.
  • Ask the help something (the ? button) and open Settings (the gear).
  • In Settings → Cleaning, turn on the weekly automatic cleanup and the low-space alert.
  • Use Claude Code or Claude Desktop? In Settings → AI click Connect and ask it “what's taking up space on my Mac?”.
  • If something shows up as “Unclassified”, click Explain with AI.

It's a beta: your files are kept 7 days after cleaning and can be undone, but we recommend having a recent Time Machine backup.

AI explanations need Apple silicon and macOS 26 with Apple Intelligence; without it, everything else works the same.
