Edit your files on Windows NTFS drives in macOS Monterey

Microsoft NTFS for Mac is a file system driver giving you full access for reading and writing to Windows NTFS formatted drives on your Mac. Our latest version supports the newly released macOS 12 Monterey and is also backwards compatible all the way to Mac OS X 10.4 Tiger.

With the new 2021 version, you can seamlessly use your drive between your Mac and Windows computers. This new release includes improvements to the caching layer for better performance on SSDs and hard drives, as well as various other bug fixes.

We always suggest using the latest version of our software to get the best performance and new features. For existing customers, upgrading from the previous version to this new one is free. To update, simply go to System Preferences -> Microsoft NTFS by Tuxera -> Updates tab on your Mac. Or you can always get the latest version directly from our website.

New to Mac?

If you have just switched from Windows to Mac, you might be having trouble copying files to hard drives used on Windows. This is because out of the box, Apple’s Macs only come with support for reading NTFS drives, the popular file system used in Windows. With Microsoft NTFS for Mac by Tuxera, you can read and write files to your NTFS-formatted USB drives, and use those drives on both your Mac and Windows computers.

If you don’t have a license yet, you can get one here.

Tuxera NTFS for Mac gets more reviews

Following the latest release, Tuxera NTFS for Mac is receiving positive reviews all over the net. For example movie and television industry veteran David Roth Weiss has in mind a use case where large movie files are post-produced on a Mac and then submitted to clients who have PCs:

Until Tuxera, the 4Gb file size limitation made it impossible to copy files over 4Gb to a FAT32 formatted drive, and NTFS formatted drives could only be read on Macs, writing to them was not possible. ... that could be a real deal breaker for many editors on Macs. Tuxera changes all that, and creates a seamless method for delivering files on hard drives to your PC-based clients.

Earlier also MacObserver picked Tuxera as the NTFS solution for Mac.

As a final note, Softpedia gave us "100% CLEAN" award :)

Release: Tuxera NTFS for Mac 2010.1

The latest release of Tuxera NTFS for Mac is now out!

Note: This release contains an important bugfix for the issue described in KB974729. All users are urged to update as soon as possible.

Changes since 2009.10:

  • A fix for the issue described in KB974729, in which NTFS drives were rendered unmountable in Windows Vista and Windows 7 in rare cases after being used extensively with Tuxera NTFS for Mac or NTFS-3G. After this update, Tuxera NTFS for Mac will no longer trigger this condition.
    To fix existing drives, please install the hotfix provided by Microsoft and follow instructions.
    If you have been affected by this issue and need assistance, don't hesitate to contact our premium support email address (see your activation email).
  • Performance improvements: Tuxera NTFS for Mac now includes many of the improvements featured in Tuxera NTFS for Embedded systems, designed to further increase performance and reduce unnecessary driver workload, especially when working with many smaller files and traversing large directory hierarchies.
    For example, when crawling a test volume recursively, 2010.1 was nearly 40% faster than 2009.10 in our tests.
  • Performance improvements: The caching layer has been improved with more efficient lookup, which means less CPU overhead, and measures have been taken to minimize the amount of excess data that is read when accessing files in a random fashion.
  • Feature: Tuxera NTFS for Mac now includes a new preference pane option "Disable recovery dialog for hibernated volumes", which makes the driver ignore NTFS volumes that contain a hibernated Windows session instead of showing a dialog asking the user whether it wants to purge the hibernated state or abort mounting.
  • Bugfix: Fix for some users of Snow Leopard who had problems with formatting NTFS volumes (Tuxera NTFS was not displayed as a formatting option at all times).
  • Fix: General usability improvements in the installer and preference pane.
  • Fix: Minor fixes to improve compatibility with the built-in NTFS driver.
  • Experimental: Tuxera NTFS for Mac now attempts to mount Windows LDM partitions by default. This will not work at all times, but one user did benefit from this change.

Award for Tuxera NTFS Mac

AT-AWARD-SILVERGerman computer magazine Apfeltalk ("Appletalk") has reviewed Tuxera NTFS for Mac (Google translation). The product was thanked for its unbeatable performance and flawless operation compared to competition. Tuxera NTFS for Mac was recommended with a Silber-Award ("Silver Award"), something we are very proud of!

Release: Tuxera NTFS for Mac

We are proud to present the Tuxera NTFS for Mac 2009.10 release!

Changes since version "1.0-RC":

  • Preference pane internal classes were renamed to avoid a namespace collision with the NTFS-3G preference pane. If you had both NTFS-3G and Tuxera NTFS installed you could experience some strange behaviour in System Preferences.
  • Version number scheme changed to year.month[.revision].

Tuxera NTFS for Mac licenses can be purchased from the Tuxera Online Shop. As a customer, you are entitled to free updates. Your product key will continue to function in updated versions of the driver.

We also have a dedicated customer support email address where you can reach us and get help with the product, or get feedback on any problems that you may have.

Technical briefing

We were asked for a technical write-up regarding the changes that have been made to the NTFS driver for Tuxera NTFS for Mac, so I'm going to make an attempt to describe what we have done.

The most important issue that we identified when studying how to build a commercial grade product from the existing NTFS-3G for Mac OS X product was that performance still wasn't optimal. This has been a problem for NTFS-3G from day one, caused by inefficient kernel/userspace interfaces to the raw disk devices provided by the Mac OS X kernel. Even after applying relevant patches to supply a caching layer between the disk device and the file system driver, we never fully reached the performance level that we would have desired.

Also, the existing caching layer (originally from the FreeBSD port of NTFS-3G) introduced a new problem: written data could stay in memory for long periods of time without being flushed to disk. This means that if the Mac would run out of battery, encounter a system crash, or if someone would disconnect an external drive without unmounting it first, then the latest changes to the data on the NTFS drive would not have reached the disk. The result in this situation is that people would lose the latest data that was written to the NTFS volume. Volume inconsistencies needing to be fixed with 'chkdsk' in Windows would also be very likely.

Essentially with NTFS-3G, people were forced to choose between better performance (caching on) and keeping the data safe in the event of a system crash (caching off).

We eventually decided to write a new caching layer from scratch, partially to be able to experiment with performance and to squeeze the best performance out of the disk, but also to be able to incorporate smart cache flushing to ensure that data doesn't stay in memory longer than it absolutely needs to.

This proved to be very successful. With the new caching layer we have in many cases recorded performance comparable to and in some cases even better than the built in HFS+ driver.

Additional improvements have been made. Some examples:

  • Implemented support for the Mac OS X "Locked' and "Hidden" features for files, mapped to their NTFS equivalents (readonly, hidden). This can be used to make files immutable by "locking" them, just like on HFS+ volumes.
  • Adaptive file ownership: The files on an NTFS volume always appear to be owned by the user currently accessing it.
  • Support for putting files in the 'Trash' bin (in NTFS-3G, you could only delete them directly).
  • Some bug fixes that will eventually appear in NTFS-3G as well, for instance: Firefox wouldn't save files on an NTFS volume, International (non-ASCII) volume names led to an error when mounting...

We have also reconstructed the preference pane, added help content, and in many other ways made sure to iron out the small quirks and irregularities encountered in NTFS-3G, to make sure that we deliver a polished, tested and well-functioning product for the commercial market.
