About

A small utility, built in the open.

Mountee exists for a narrow reason: macOS can read Windows drives but will not write to them, and the usual workarounds ask you to weaken your Mac or install a chain of drivers. We wanted a better default.

The project

Free NTFS read/write without the security tax.

Mountee is an independent, open-source project by Alvaro Lorente. It builds on Apple's FSKit framework and the upstream ntfs-3g engine. The engine is compiled into the app so there is no macFUSE install and no third-party kernel extension.

The project is intentionally conservative. Volumes mount read-only by default. Writes are explicit per volume. Dirty or Windows-hibernated volumes are never mounted read/write. Mountee never formats, repairs, or erases anything. When it cannot do something, it says so instead of pretending.

It is also young: version 0.2.0, first released in October 2026. The documentation publishes the limits alongside the features. That is deliberate. Trust is easier to build when the boundaries are visible.

Principles

What we optimize for.

Safety over convenience

Read-only is the default. Dirty volumes stay read-only. Unsupported operations fail loudly. Convenience is never worth silent data corruption.

Honesty over marketing

Platform requirements, missing POSIX permission mapping, and untested crash consistency are documented. No fabricated ratings or testimonials.

Open over closed

GPL-3.0 source, public build scripts, and a pinned engine. You can audit the safety gates, fork the project, or build it yourself.

Sustainability

Free, with optional support.

Mountee has no paid tier, subscription, account, or feature gate. It is GPL-3.0 and stays that way. Development is supported by optional sponsorship and community contributions.

If Mountee saves you time, you can sponsor the project, report a reproducible bug, improve the documentation, or contribute code. None of those are required to use the app.

Project documentation

The repository contains the development guide, diagnostics guide, validation checklist, full limitations list, and third-party notices.
