Install Mountee

Download and install Mountee on macOS 26 or later, enable the file system extension, and mount your first NTFS volume.

Updated November 14, 2026 Verified against release 0.2.0

Mountee installs from a signed and notarized DMG. There is no macFUSE, Homebrew, kernel extension, Recovery Mode, or reboot step.

Requirements

  • macOS 26 or later on an Apple Silicon Mac. Verified on macOS 26.6.2 and macOS 27.0.1.
  • An NTFS-formatted volume and the appropriate USB-C, Thunderbolt, or card-reader connection.
  • No additional software. Mountee bundles its NTFS engine.

Intel Macs and macOS 15 or earlier are not supported.

1. Download the current release

Download the latest verified DMG from mountee.app/download or from GitHub Releases.

The 0.2.0 installer is named MacNTFS-0.2.0.dmg and installs MacNTFS.app. This is the same Mountee project; the app name is being migrated in a future release. The website uses the Mountee name throughout.

Optional integrity check:

shasum -a 256 ~/Downloads/MacNTFS-0.2.0.dmg

The published SHA-256 for 0.2.0 is:

cd718a001591097c0f71ad703c3bd239a17606f61285958b48a4b368dc645e3f

2. Install the app

  1. Open the DMG.
  2. Drag MacNTFS.app to the Applications folder.
  3. Launch it once. This registers the FSKit file system extension with macOS.
  4. The app appears in the menu bar. It does not open a normal document window.

If you are upgrading, quit the running app first. The 0.2.0 build uses the same bundle identifiers and stores data under ~/Library/MacNTFS, so existing extension enablement and preferences remain associated with the app.

3. Enable the file system extension

In the Mountee menu bar window, press Enable File System Extension if the status is not Enabled.

You can also enable it in System Settings → General → Login Items & Extensions → File System Extensions. This is per-user: enable it once in each macOS account that should mount NTFS volumes.

On macOS 26, a system bug could prevent the System Settings toggle from enabling third-party FSKit modules. If the toggle does not stick, use the app’s enable button. macOS 27 fixes that bug.

4. Mount a volume

  1. Connect the NTFS drive.
  2. Open the Mountee menu bar window.
  3. Choose Mount Read-Only for safe access, or Mount Read/Write to allow writes.

Volumes mounted through Disk Arbitration appear under /Volumes. When Mountee falls back to the direct mount -F path, the mount point is ~/Library/MacNTFS/Volumes/<name>. Either way, the volume is available in Finder.

Read/write is always explicit. Mountee never mounts a dirty or Windows-hibernated volume read/write.

Verify the download

The release is Developer ID signed and notarized by the project’s release pipeline. To inspect the app signature:

codesign --verify --strict /Applications/MacNTFS.app
codesign -dv --verbose=2 /Applications/MacNTFS.app

Do not disable SIP or reduce macOS security to install Mountee. If macOS blocks the app, confirm that you downloaded it from the official GitHub release and follow Apple’s standard Gatekeeper instructions.

Uninstall

  1. Eject all mounted volumes.
  2. Disable the extension in System Settings → General → Login Items & Extensions → File System Extensions.
  3. Delete the app from /Applications.
  4. Remove ~/Library/MacNTFS.

There is no kernel extension or third-party driver package to uninstall; disabling the FSKit extension and deleting the app is the complete removal.
