MakeRoom for Mac
Download MakeRoom
One disk image for Apple silicon — a beta, not yet notarized by Apple, so macOS asks you to approve it once. Its version, its size and the checksum of the exact bytes are below, because it is about to read your whole disk.
Cleaning this Mac is free forever, with no account and no network connection. The download starts immediately; nothing asks for an email address first.
SHA-256 MakeRoom.dmg
Not published yet. It appears here with the first signed release.
shasum -a 256 ~/Downloads/MakeRoom.dmg prints the same line for the file you downloaded.
- File
MakeRoom.dmg— a disk image holding MakeRoom.app and nothing else. No installer runs, and nothing is placed outside the app you drag to Applications.- Version
- 0.9.0, in beta. Published 2026-10-09. What changed.
- Built for
- Apple silicon, macOS 15 Sequoia or later. There is no Intel build, and no App Store build — whole-disk inspection is not possible inside the App Sandbox.
- Signature
- A beta build: Hardened Runtime, signed ad-hoc, and not yet notarized by Apple. That is why macOS asks you to approve it once, below. A notarized release replaces it once the Developer ID is in place; until then the SHA-256 above is how you check the file is the one we built.
- What it costs
- Nothing, and nothing is for sale: there is nothing to pay and nothing to cancel. Cleaning needs no key and no account; moving off this Mac needs a key, which is issued free on the web after a 14-day trial here. What that means.
- macOS
- macOS 15 Sequoia or later.
- Hardware
- Apple silicon. MakeRoom is a hardened direct download, in beta and not yet notarized by Apple — whole-disk inspection is not possible inside the App Sandbox, so it is not on the Mac App Store.
- Permissions
- None to start. MakeRoom scans everything macOS lets it read as you, and names what it left out. Full Disk Access is offered afterwards, in the result it would widen, and never as a gate to opening the app.
- Release
- Version 0.9.0, in beta. The main journey works end to end and parts are still being finished, so you may meet rough edges. What beta does not change: cleanup goes to the Trash rather than being deleted outright, and nothing leaves this Mac before its copy on the drive has been verified.
- Open it
- Double-click the image, drag MakeRoom to Applications, eject the image. Open MakeRoom once and close the warning that it cannot be verified, then go to System Settings → Privacy & Security and choose Open Anyway. macOS asks once per version. In Terminal instead:
xattr -dr com.apple.quarantine /Applications/MakeRoom.app. - After an update
- While builds are not notarized, macOS sees each new version as a different app: approve it once again, and grant Full Disk Access again if you had. Your scan history and settings carry over.
- It asks for nothing
- MakeRoom scans whatever macOS already lets it read as you, and names what it left out. Full Disk Access is offered afterwards, inside the result it would widen — never as a gate to opening the app.
- It stays here
- No path, filename or scan result leaves the Mac. The one request MakeRoom can ever make is a version check, off until you switch it on in Settings. Privacy.
- Removing it
- Dragging the app to the Trash is the whole of it, with one thing worth reading first if you have moved data to a drive. Uninstall and recover by hand.
In this version
0.9.0 · 2026-10-09
The first release. A native macOS app that scans the whole Mac with the access it has and names what it did not cover, explains where the space went, and recognises developer data by its layout: Rust, Node.js, Xcode, Android, Go, Python, Swift and Gradle build output and caches, containers, Homebrew and local AI models. What your tools can rebuild is cleaned to the Trash, never deleted outright; what they cannot is moved to a drive through a journaled, verified transfer that leaves a link at the original path, repairs itself when the drive returns elsewhere, and can be restored in every state. Cleaning is free forever, with no account and no network connection; moving is the one capability a key covers, after a 14-day trial, and a key is free, activates offline and names exactly one Mac. Also: saved routines that re-scan and stop at a review, Externalized and History views, a default-off agent endpoint for a program you approve, and flat tinted glass in dark and light.
