⟲ The Safe, Undo-able Mac Cleaner v1.2

Clean your Mac.
Never lose a file by accident.

KaiCleaner finds the caches, logs, and developer junk eating your storage — then moves everything to the Trash instead of deleting it outright. A wrong guess costs you nothing.

How to install — the download is a disk image (KaiCleaner.dmg), not a text file. Do not open it in a code editor.
  1. Double-click KaiCleaner.dmg in Finder
  2. Drag KaiCleaner into your Applications folder
  3. Open KaiCleaner from Applications — Gatekeeper should show no warnings

Built for a locked-down macOS

System Integrity Protection and the read-only system volume exist for a reason — aggressive cleaners that fight them are how you end up with a broken app or a kernel panic. KaiCleaner doesn't fight macOS. It works within it.

✓ Never permanently deletes — everything goes to the Trash
✓ Only touches your own home folder by default
✓ Safe mode skips files modified in the last 24 hours
✓ Stop any scan mid-way — partial results, no half-finished cleanup
✓ Full Disk Access is detected at runtime — not just a toggle

What we never touch

Even with Full Disk Access enabled, KaiCleaner blocks these paths by design.
