As the default Windows disk format, NTFS drives are probably the most common drive type in the world. Unfortunately, macOS cannot write to NTFS drives by default. This makes working between operating systems far more difficult, requiring either a compatible disk format like ExFAT or tools that allow macOS to write to NTFS drives.

Your Mac can read NTFS drives, transferring content from the drives to another place, but it cannot write to NTFS drives. Write support for NTFS drives can be added through open-source programs, paid programs, or Apple’s own experimental drivers.

The Free But Complex Method: NTFS-3G

Mac OS X supports a handful of common file systems—HFS+, FAT32, and exFAT, with read-only support for NTFS. It can do this because the file systems are supported by the OS X kernel. If you are in Mac OS X and want to mount (i.e. Access) an NTFS drive, support for NTFS is OS X can be dodgy, but you can get software that will install a driver to enable Mac OS X to read the NTFS disk properly. I've never used it myself so I can't recommend anything in particular, but if you google for it you should find something.

NTFS-3G is an open-source command-line program for writing to NTFS drives in macOS. With this Terminal command you can mount drives in macOS in a writable state. You can download the package directly from the Tuxera website, from GitHub, or with Homebrew.

One downside of NTFS-3G is its speed. Transfer performance is slow, often limited to about 10 MB/s. Compared to the 500+ MB/s achieved by an SSD, the difference is dramatic. This happens because macOS does not have a buffer for writing to NTFS drives, nor the virtual memory to hold that buffer. So NTFS-3G is forced to write “live,” which degrades performance significantly.

To mount your NTFS drive, you’ll need to use Terminal. First, create a directory to which you can mount the NTFS drive:

Now that this directory exists, you can use NTFS-3G to mount.

Of course, this assumes that you’ve put the NTFS-3G program in its default install path. Additionally, be sure to change the disk number before mounting anything. If you don’t know what number your disk is, find it with diskutil list.

Automatically Mount Drives with NTFS-3G

To automatically mount drives in read-write mode, you’ll need to replace Apple’s default NTFS program with NTFS-3G. This will automatically mount the NTFS drives connected to your Mac each time you boot it up. In order to make this work, you must disable System Integrity Protection (SIP) on your Mac. NTFS-3G can only run properly with root permission.

This will create a symbolic link to NTFS-3G’s mounting command. Your computer will now use this driver to mount NTFS drives instead of the default. If you need to replace the program, it’s in your “/sbin/” directory with the extension .bak.

The Paid But Easy Method: Paragon NTFS for Mac

Paragon NTFS for Mac (also known as Microsoft NTFS) is commercial software that supports writing to NTFS volumes on macOS. It’s definitely the most user-friendly way to make NTFS drives writable in macOS, but you pay for that privilege. It uses Microsoft-designed kernel extensions to support writing to NTFS volumes. It’s a fast, seamless solution that supports high transfer speeds and easy mounting and unmounting.

Enable Apple’s Experimental NTFS Support

Your Mac actually comes with some limited NTFS drivers. Because they’re not highly reliable, they are disabled by default. If you want to take the risk and try them out, you’ll need to edit your system’s fstab file.

Run the following command in Terminal to open the fstab file:

Once the file is open, add a new line. This line should appear similar to the following, but simply change the UUID value to reflect your NTFS drive’s UUID value. If you don’t know the UUID value, that can be found with diskutil info.

Then press Ctrl + O to write the file and Ctrl + X to exit nano. When your drive is reconnected and your Mac rebooted, the drive with automatically be mounted. However, it may be unstable, so don’t rely on it too heavily. And if things break, you can’t say we didn’t warn you!

Conclusion

The best bet for ease of use will clearly be Paragon NTFS for Mac. If you’re comfortable with Terminal, you can use NTFS-3G and see if it meets your needs. If you only occasionally deal with NTFS drives, you may find it is sufficient.

OS X supports the option to read NTFS-formatted drives, but has not supported writing to these drives. Therefore, the use of a third-party driver such as Paragon NTFS or Tuxera NTFS has been required for those seeking full NTFS support; however, OS X does support writing to NTFS, but this feature is just not enabled by default.

To enable this feature, you have to do so on a per-volume basis, by editing the system's hidden fstab file to adjust the way the drive is automatically handled when attached and mounted.

First ensure that your NTFS drive has a simple single-word name, and then go to the Applications > Utilities folder and launch the Terminal program. In here, run the following command to edit the fstab file (supply your password when prompted):

sudo nano /etc/fstab

The Terminal should now show an editor window for the fstab file, in which you can enter the following all on one line. Be sure to change the word NAME to the name of your drive (it is case-sensitive):

LABEL=NAME none ntfs rw,auto,nobrowse

When finished, press Control-O to save the file, followed by Control-X to exit, and then unmount your NTFS drive and attach it again. When you do so, the system will no longer immediately show it in the Finder, but you can go back to the Terminal and run the following command to reveal it in the hidden Volumes directory where the system mounts all attached drives:

open /Volumes

In the folder that opens, you should see the mounted NTFS volume, and should now be able to copy files to it, or otherwise manage files on it. If you need to access this volume more frequently, you can drag it to the sidebar, or make an alias of it in the location of your choice. You can also view the Volumes directory in Column mode to reveal it as a parent directory, from which you can create an alias instead of doing so on a per-drive basis.

Keep in mind that the writing ability of Apple's NTFS driver has not been thoroughly tested, and though this will enable write support using Apple's driver, there may be some limitations or unknown behaviors with the driver, so use it with caution. If you are dealing with important data, or need to access numerous different NTFS volumes, then third-party drivers may still be the best (if not most convenient) choice.
