How To Format Ntfs Fuse For Mac Os X

How To Format Ntfs Fuse For Mac Os X


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

To format to ntfs in osx. Without paying for macdrive, I want to be able to use my external hdd on both mac and pc for read/write purposes. Mac OS X is not Windows, so it doesn't run on shit file systems like Ntfs. Here is a suggestion, if you have leopard install Bootcamp, and you will have the best of both worlds. Though Apple supports exFAT, an alternative format also created by Microsoft to read/write OS X and Windows, the fact remains that Windows drives are formatted with NTFS by default.

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 NTFS-3G support forum at


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 You will need at least version 3.0.

Then, if you don't have it yet, install the package manager 'Homebrew' as described on

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.



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.

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.


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

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.

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 ln -s '/Volumes/Macintosh HD/usr/local/sbin/mount_ntfs' mount_ntfs
  • 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'.

So far it is considered that mounting NTFS means opening an NTFS formatted drive in Mac operating system. But it is not true. Have you ever thought that opening a drive in Windows is not called “Mounting a drive”? To explain it technically, the mounting process is not done by the hardware process of the PC. In Mac based operating systems before the boot of any storage devices by the PC the user or the operating system has to mount the storage drives using mount point and file systems. Moreover the operating system cannot be forced to open an uncategorized or unsupported format. So the mounting process will ensure that the requested drive is supported by the PC and the operating system.

In the case of mounting NTFS in Mac, the Mac operating systems do not give read / write permissions to the users because of legal issues or sometimes the read process alone will be permitted. But this New Technology File System will store additional information like files accessing time and date along with that data. So in NTFS even the read process will be considered as write process only.

Ultimately Mac is one of the leading big bosses in the operating system industry. But roughly around 70% of the people all over the world make use of Windows OS. Since no other file system is well suited for drive storages of larger size. It is the most used files system for many external drives as it also supports journaling files and that will be useful at the time of recovery of crashed data. Since the read and write process are merely same the Mac OS 10 x versions will not permit the drive to be mounted.

The NTFS comes under Microsoft developed one which is one of the legal obstacles for Mac OS to have legal permissions to boot and mount NTFS drive at startup or automatically. But the Mac OS from 10.3 x and later version has the options to perform read/write on NTFS drives and storage devices. The typical part lies in answering the question “How to mount a NTFS drive on Mac OS X”.

Even though the Mac OS has this option it fails to initiate automatically. If the users want to use an NTFS drive in a Mac based pc then they have to remove the restriction to read/write either manually or by using a third party application. To do it manually the user needs some basic knowledge about working in a Mac terminal. Regarding using a third party applications for mounting NTFS drive in Mac the naïve user must need to choose between the free one and the paid one. One of the free one is Mac fuse, the other used tools are NTFS – 3g and paragon.

Actually what this applications do is they will fetch the memory as a normal application from the Mac OS memory. When the user prompts to open an NTFS drive using this application they will create a simulated environment in the back and also make use of a rearranged hash table. This helps to perform read/write operations in NTFS drive. But sometimes working with third party applications will be rigorous because the third party applications will convert the files from NTFS to HFS+ or HFSX. In certain times, the conversion will be troublesome. Like trying to access a compressed files of size 9 GB, there appears the application crash and the drive will be unreadable further.

When the same drive is used in the Windows operating system an error message will be received stating that “read / write error. Do you want to format the drive now?” If you have any important data on that particular drive, you may lose the same after forcibly formatting the drive. However, as far as data recovery is concerned, you can try to make use of good recovery software like Remo Recover Mac – Pro that has the option to retrieve files from formatted disk / drives. It is recommended as the best software in the market.
