How to clean up your Mac's storage, safely

Five tools, one scan

Space on a Mac goes to a few kinds of things: files apps made for themselves, a handful of very large files, copies of the same file, and photos you meant to sort. Each needs a different way of finding it, so Clean up has a tool for each:

• Junk Cleaner clears caches, logs, old installers and developer junk, with the risky categories left unticked.
• Large Files lists the biggest files on your Mac and labels each one Safe to delete, Review or Keep.
• Disk Map draws every folder as a block sized by its space, so you can see what is taking up room.
• Duplicates finds files with identical contents and always keeps one copy.
• Photos groups near-identical shots and old screenshots, and suggests the best photo to keep.

Junk Cleaner, Large Files, Disk Map and Duplicates share one pass over your disk: press Scan in any of them and all four have their results.

Nothing goes without a preview

Every tool shows what it found before anything is removed, and what you remove goes to the Trash, or to Recently Deleted for photos in your Photos library. Duplicates and Photos never let every copy go. The few things that can't go to the Trash, such as emptying the Trash itself or deleting local Time Machine snapshots, are unticked by default and say so before you confirm. The cleanup history on the Dashboard lets you Put Back anything that went to the Trash.

Scans read file names, sizes and, to compare duplicates and photos, file contents, all on your Mac. Nothing is uploaded; the Privacy Policy lists every request the app makes.
