- For
- Mac users diagnosing slowdowns or reclaiming disk space
- Worth noticing
- It blocks deletion of keychains, SSH keys, home-folder and macOS system files; unreadable folders are marked Locked.
Field notes
The monitor groups an app's processes into a single line—for example, Chrome's roughly 35 processes—and can identify a leftover script such as python3.12. Cleanup separates disk browsing from Quick Clean: the latter limits its list to caches, logs and developer files, while documents, photos and downloads are excluded. The page says disk selections go to the Trash, but caches and logs are deleted immediately.
