NTFS for Mac OS X (10 Days Trial): I use this one, and it does the job very well. When the driver is installed, you format your NTFS disks with Disk Utility where you select Windows NT Filesystem as the format. Tuxera NTFS for Mac (15 Days Trial): I haven't tried this one, but it should also do the job. Read or Write NTFS Drive on Mac with Easy Driver (Safe & Fast) Your Windows NTFS drive is not.

Features

As a user, installing the FUSE for macOS software package will let you use any third-party FUSE file system. Legacy MacFUSE file systems are supported through the optional MacFUSE compatibility layer.

Fuse

As a developer, you can use the FUSE SDK to write numerous types of new file systems as regular user space programs. The content of these file systems can come from anywhere: from the local disk, from across the network, from memory, or any other combination of sources. Writing a file system using FUSE is orders of magnitude easier and quicker than the traditional approach of writing in-kernel file systems. Since FUSE file systems are regular applications (as opposed to kernel extensions), you have just as much flexibility and choice in programming tools, debuggers, and libraries as you have if you were developing standard macOS applications.

How It Works

In more technical terms, FUSE implements a mechanism that makes it possible to implement a fully functional file system in a user-space program on macOS. It provides multiple APIs, one of which is a superset of the FUSE API (file system in user space) that originated on Linux. Therefore, many existing FUSE file systems become readily usable on macOS.

The FUSE for macOS software consists of a kernel extension and various user space libraries and tools. It comes with C-based and Objective-C-based SDKs. If you prefer another language (say, Python or Java), you should be able to create file systems in those languages after you install the relevant language bindings yourself.

Ntfs

The filesystems repository contains source code for several exciting and useful file systems for you to browse, compile, and build upon, such as sshfs, procfs, AccessibilityFS, GrabFS, LoopbackFS, SpotlightFS, and YouTubeFS.

NTFS-3G is an open source cross-platform implementation of the Microsoft Windows NTFS file system with read-write support.

Please note that NTFS-3G and FUSE for macOS are independent projects. Should you run into NTFS-3G related issues please post the issues on the Tuxera NTFS-3G support forum (inactive) or the SourceForge mailing list.

  • Frequently Asked Questions

Installation

The following instructions assume that you know how to use Terminal. Doing this the wrong way could damage your operating system.

First, download and install the latest release of FUSE for macOS from http://osxfuse.github.io. You will need at least version 3.0.

Then, if you don't have it yet, install the package manager 'Homebrew' as described on https://brew.sh.

Install NTFS-3G from Homebrew by opening a Terminal and entering the following command.

After installing NTFS-3G you can manually mount NTFS volumes in read-write mode by executing the following commands in Terminal. Replace /dev/disk1s1 with the actual NTFS partition you want to mount. You can find the partition name using diskutil list.

Auto-mount NTFS volumes in read-write mode

Even though you have installed NTFS-3G, newly connected NTFS volumes will still be auto-mounted in read-only mode. To change this you need to replace Apple's NTFS mount tool /sbin/mount_ntfs with the one provided by NTFS-3G.

It is important that you understand the security implications of what you are about to do. The mount tool is executed with root permissions. This means that NTFS-3G's mount tool will be executed with root permissions, too. Due to the way Homebrew installs software packages, NTFS-3G's mount tool is not protected from being tampered with by unprivileged attackers, essentially giving those attackers root access to your Mac. This is a major security risk. You have been warned.

SIP notes

On OS X El Capitan files in the /sbin directory are protected from being tampered with by a new security feature called System Integrity Protection (SIP). SIP does not protect you against the security threat outlined above.

To replace /sbin/mount_ntfs with the version provided by NTFS-3G you will need to reboot your Mac in recovery mode before proceeding. See https://support.apple.com/en-us/HT201314 for details on how to start the recovery system.

Once in recovery mode open a new Terminal window from the Utilities menu.If volume is APFS, then it will need to be unlocked to install mount_ntfs. Let's assume that Macintosh HD is identified as disk1s1.

To replace Apple's NTFS mount tool with the one provided by NTFS-3G execute the following commands in Terminal. This will back up the original mount tool to /Volumes/Macintosh HD/sbin/mount_ntfs.orig.

Uninstallation

Mac

To uninstall NTFS-3G, open a Terminal prompt and enter the following:

Microsoft ntfs for mac

If you have replaced Apple's NTFS mount tool /sbin/mount_ntfs with the one provided by NTFS-3G to auto-mount NTFS volumes in read-write mode you will need to restore the original mount tool.

SIP notesOn OS X El Capitan files in the `/sbin` directory are protected from being tampered with by a new security feature called System Integrity Protection (SIP). You will need to reboot your Mac in recovery mode before proceeding. See above for details.

To restore Apple's NTFS mount tool execute the following command in Terminal.

Auto-mount NTFS volumes in read-write mode on macOS 10.15 Catalina

This is a advanced guide. If you can't use Terminal please STOPPPPPPP

  • Reboot macOS to Recovery Mode (Turn on your Mac and immediately press and hold Command (⌘)-R.)
  • Disable SIP with command csrutil disable, you need to reboot mac device. Please note reboot to Recovery Mode
  • Open Terminal in Recovery Mode from Menu bar -> Utilities -> Terminal
  • Get list disk available with command diskutil list
  • Please flow a label (synthesized) - this is disk installed macOS. See NAME column, a name as Macintosh HD - Data - this is a general name, it can unlike your mac device.
  • See IDENTIFIER in this row. A identifier like disk2s1
  • Unlock this volume with command diskutil apfs unlockVolume disk2s1
  • Go to system folder sbin with command cd '/Volumes/Macintosh HD/sbin'
  • Backup apple original mount_ntfs use command mv mount_ntfs mount_ntfs.orig
  • Set NTFS 3G as default mount_ntfs with command:
  • You can re-enable SIP with command csrutil enable
  • Reboot to normal mac

Frequently Asked Questions

1. Why is NTFS-3G's write performance so poor?

The ntfs-3g program opens and does I/O to the block device /dev/disk[number] of the NTFS volume in question. macOS does not have a VM buffer cache for block devices when they are accessed in this way. That is the most overwhelming factor, because both metadata operations and file data I/O boil down to read-writes by NTFS-3G to the block device.

Suppose we somehow automagically provided unified buffer caching for block devices by essentially making a disk look like a giant file. Even then, macOS and its buffer cache is really happy only when you do I/O that is in units of page size (4KB) and aligned on a page boundary. To get the most out of the I/O subsystem in macOS, ntfs-3g (or any other program for that matter) would really want to do I/O in multiples of 4KB.

For comparison, you should try writing to an NTFS disk image. You will see that it is considerably faster because you do have some caching in that case.

2. After installing NTFS-3G, my Boot Camp volume stopped showing up in the 'Startup Disk' preference pane. Is reinstalling macOS, Boot Camp, and Windows the only recourse?

Relax. The 'Startup Disk' preference pane is simply filtering out (that is, not displaying) any mounted volumes that it does not consider bootable. Its definition of a Boot Camp volume includes that the mounted volume either be of type msdos or ntfs - this is hardcoded into the preference pane plugin. This does not mean your Boot Camp volume has become unbootable. It is merely not showing up in the graphical user interface. You can hold the 'opt' key during startup and choose the Windows partition to boot from. You can also remount it (read-only) using the NTFS file system built into macOS and it should start showing up in 'Startup Disk'.

Fuse For Macos Ntfs

3. I don't like the AppleDouble ._ files on my NTFS drive. Can I turn that off?

Fuse For Macos Mount Ntfs

Yes! There are actually two approaches to removing them:

  • You can add -o noappledouble to forcibly turn off access to these files. This is preferable for removable drives, since permissions don't really matter.
  • You can remove the auto_xattr part from the mount options and replace it with streams_interface=openxattr. This completely opens up the NTFS streams interface for storing extended attributes, so AppleDouble files are no longer required.
    • If your ntfs-3g is built with --enable-extra, you can actually map Windows users onto Unix permissions and use it like a normal drive. You might want to turn off inherit so you can properly use chmod. Also turn on -o extended_security if you want ACL.

Ntfs For Mac

Note: AppleDouble files are meant for storing extended attributes like advanced ACL permissions and Spotlight tags when there is no xattr support. If you turn AppleDouble off without an adequate xattr mechanism, stuff can fail.

Note 2: NTFS-3G had a bug that prevents macOS from understanding when an attribute is missing. A fix is available, but it is yet to be included in a release.
