About DiskWise

Free, open-source CleanMyMac alternative for macOS. Native SwiftUI disk cleaner for app caches, node_modules, Xcode DerivedData and Docker usage - nothing is ever really deleted: it all goes to the Trash and stays undoable. No telemetry, no daemon, no subscription.

What is new in DiskWise 1.7

**DiskWise 1.7** — the first build that is signed with a Developer ID certificate and notarized by Apple, so it opens on a double-click. No more "System Settings → Privacy → Open Anyway".

- **A folder drill page.** Large Files only ever showed a top list, and much of that list sits in system locations you can't delete, so "what is actually inside this folder" had nowhere to go. Enter any folder and each level lists its subfolders and files together, sorted by size on disk, one click to go deeper. You arrive from an overview ledger row, or from "Open containing folder" on the Large Files and Long Untouched pages.
- **Rows now say what the knowledge base knows about them.** A second badge and a second line: what the path is, what deleting it costs, and how it comes back. The footer accounts for the whole level — how many entries are known and safe, how many need a look first, how many aren't in the knowledge base at all. For `~/Library` that last number is 93 of 95, and not listed does not mean safe to delete.
